Combining Two Audio Interfaces Using ASIO4ALL using ADAT as Clock Link

Have you ever wondered how to use two audio interfaces to expand for additional microphone inputs and audio outputs? It is not as simple as connecting them to your PC.
A tutorial on the basics and the importance of clock sync between two devices.
A Demonstration of how to set it up for Windows OS using ASIO4ALL Driver.

This makes no sense. If I have two audio interfaces with ADAT in and out and 8 analog inputs and outputs on each, I can just take the ADAT out from #2 bring it in to the ADAT in to #1, run the ADAT out from #1 to the ADAT in to #2, and then just use interface number #1 with whatever driver it comes with (no need to use ASIO4ALL) and have access to all 16 analog inputs and outputs on both interfaces through interface #1 to the computer. I can then use the interface software to route all channels however I like and see them all in my DAW where I can set the clock to "internal" for both interfaces to slave to through the ADAT connections. If your method was correct (and I've never seen anyone use ASIO4ALL to successfully combine two input or output interfaces), then I should be able to run 2 ADDITIONAL AD converters (like the Behringer ADA 8000 / 8200) to feed each of the audio interfaces and combine the two interfaces in ASIO4ALL to get 32 inputs and outputs with the ADAT handing the clock OR just use a dedicated external world clock to sync all 4 devices and the DAW PC. Unfortunately, I think that ask that you've done here is to make use of the ADAT input into your main interface to use the extra 8 ADAT in channels which is a well - documented feature of the audio interface, anyway. You don't even need to waste a USB port on your DAW computer, because it doesn't need to pull audio from the interface. It can do it with just the ADAT connection going into the primary interface connected to the DAW. Lastly, there's a maximum number of channels you can bring into a PC using a USB 2.0 port. My RME Digiface USB interface takes 4 ADAT ins and 4 ADAT outs that connected to any ADAT - enabled AD preamp (like the Behringer ADA 8000 / 8200) or any audio interface with ADAT ins and outs to combine them into a 32 channel in and 34 channel out (it has s headphone port) interface through a single USB 2.0 cable. But that basically maxes out the capacity of the USB 2.0 port. I'd love it if you were correct, though. I've got 4 audio interfaces with ADAT in and out and 2 Behringer ADA 8200s. If you were right, I could buy 2 more ADA 8200s and then have 64 channels of inputs and outputs and sell my Digiface USB. Unfortunately, ASIO4ALL can't (from what I understand) do this in a reliable way. It's what makes those damned Apple computers better for audio recording. They can combine interfaces right in the OS where Microsoft won't get off of their asses and fix their crappy audio system.

[@RecordingStudio9]

Thanks for your comment. Unfortunately, you are missing one important information in your analogy. Unless you are using high-end audio interfaces, budget interfaces that have ADAT, DO NOT connect their analog inputs and outputs to ADAT, they just go to USB. And ADAT only sends/receives from USB. So, you can't connect one interface to another with ADAT in/out and expect it to work Only a few high-end interfaces that have built-in DSP, like MOTU, RME, etc that will allow you to direct analog in/out to ADAT instead of USB. Here is a link to a very old video of mine showing how I used my faulty FireWire MOTU unit to act as an ADAT unit kzbin.info/www/bejne/f4XGaqmGeb9ofpI With all of my testing, ASIO4ALL can handle up to 24 or max 26 before it grinds to a halt. This is due to the fact that the clock drift and processing is now handled by the PC CPU and not the hardware unit. I have used 2different make interfaces with 8 inputs each, totaling 16 inputs, and recorded all 16 channels for over 2 hours continuously with not one sample drop. Yes, MacOS handles multiple interfaces bit better with Aggregated units, but again, the stress is still on the CPU. The best way to extend an 8 in/out USB interface with ADAT is with a dedicated ADAT Mic-Pre such as Behringer ADA8200, PreSonus DigiMax, or Focusrite Octopre etc to get 16 analog in/out. Hope this helps your confusion and now makes sense :) I hope to make a new detailed video explaining and showing what I just said, soon.

[@clamdi7739]

I would have to agree with you Mr. McCalla. I followed the video to the T and was never able to make work with 2 interfaces. Someone described to me exactly what you pointed out here and I can now have my Presonus VSL 1818 to work with one of the old Digi002 interface I have. I can now have 16 input / output channels. However, I have 2 Digi002 Interfaces. I cannot manage to find a connection that would extend the additional Digi002 along with the Presonus interface to give me 24 channels instead of 16. I am on Win10 x64. The presonus interface is used as my primary interface and I use its driver software for configuration instead of ASIO4All. If I understand correctly, you said that USB 2.0 can handle 24 channels in Windows, can you please explain how I can my interface to see all 24 channels. I appreciate your clarification though.

[@RecordingStudio9]

At this stage, I no longer care if people don't understand the basic physical facts and limitations I explain over and over again, yet again during my livestream kzbin.info/www/bejne/sJ3VYotoo52VpaM If you believe I'm wrong here and Mr McCalla is correct, so be it :P

[@mc2engineeringprof]

@@RecordingStudio9 i have 3 different interfaces with ADAT that use FireWire and not USB (Profire Lightbridge, MOTU 828 mk ii, MOTU 896) and 3 that are USB (RME Digiface USB, MOTU 828 mkii USB, Celrsonic 20/20). They all use 8 channel ADAT. Therefore, I think that your statement about USB is in error. Further, if you have more than one interface from the same manufacturer, many times you can have more than one plugged in and the driver (in Windows) will combine them as one device. I know this is true of MOTU FireWire devices and is true of RME USB devices and FireWire devices. I'm sure there are others as well.

[@RecordingStudio9]

I highly recommend you watch my video response (kzbin.info/www/bejne/sJ3VYotoo52VpaM) first before claiming I'm wrong. So, how do you have them setup to give you 48 inputs and 48 outputs, seen all 48 inputs and outputs by your DAW, with no aggregation? USB or FireWire, no different to what THE BUDGET UNIT, under $500, can do in relation to ADAT audio routing. Please show me documentation from any manufacturer that sells CURRENT audio interfaces under $500 that allows you to direct Analog input/output to/from ADAT, as well as having multiple units connected, USB or FireWire (remember, Firewire interfaces have been discontinued for many years now, apart from MOTU) and combine the inputs/outputs. Any unit that has this feature is well above $500, if not $1000. Don't mention MOTU or RME as they fall above the $1000 market. P.S. FireWire was designed to be daisy-chained, but not all manufacturers had drivers to support it. MOTU, RME, Focusrite, PreSonus and some Behringer FireWire units did support. But again, they all fall above the $500 budget. Hope that clears it.

Excellent Video and graphic explanation of a practical application for ASIO for all.I have used ASIO for all before but only to allow my TC- Helicon Voicelive 2 show up as an audio interface via it's USB connection. I also own a Voiceworks which I see is in your studio but although it works OK the LEDs seem to fail easily so I don't use it to it's potential.

[@DrumsBob]

I have a FCA1616 and a Presonus D8 and was curious about ASIO4ALL. Was quite happy to see the 1616 here, now I know exactly what to do, thanks!

[@RecordingStudio9]

You should be able to connect the Presonus D8 directly to FCA1616 ADAT in via lightpipe cable and you won't need ASIO4ALL. In your DAW FCA1616 will display 16 inputs and 8 outputs.

[@DrumsBob]

@@RecordingStudio9 Thanks for the response. I've been using the FCA1616 driver and I see all the inputs. Using 48khz. The issue is Cubase says everything is recorded at 96khz, and plays back at double speed. It also changes Cubase's project settings from 48 to 96. I change it back to 48 and it works fine. So, I'm thinking Behringer's 6 year-old driver might be the issue and therefore wanted to try Asio4all. The file sizes are 48khz size. The 1616 doesn't have a BNC connector, so I must use lightpipe.

[@RecordingStudio9]

[@ohu8one221]

So we have been running a similar setup for live band recording only the problem we found was during live recordings of a band using 16 channels and recording all 16 channels at the same time, the Presonus seemed to lack the ability of running 4 extra external monitors in addition to the two main outputs so here is what we ended up doing. We kept the 16 channels and snaked all the outputs for each channel into a 24 channel Mackie Mixer so we could control the room live but still capture all of the channels in the recording software. We bumped up the sampling rate to 2048 which resolved any latency problems and do not use the USB to the Behringer as the fiber does the work of pulling in the other 8 channels. It would be nice to see them come out with a better way to connect monitor wedges and use groupings to control what each player can hear coming out of the monitors without having to use a physical mixer to make it happen. There are only two main outputs one right and one left physically to plug in from on the back of the PreSonus to main speakers which work great for the desk jocky making individual tracks as a composer. For a live band recording it is a bit more difficult but getting better as more folks are wanting to record their jam sessions. Has anyone put three Audiobox 1818VSL's together and assigned any of the main outputs to be used to send to players monitor floor wedges? It has had its challenges, but I think we are coming to its limitations without just getting a Presonus 32 channel mixer that can record or something like it. Oh, did I mention whoever dies with the most music crap wins. When I mention monitors in the above, I'm talking about self-powered speaker wedges that sit in from of each player so they can set it to hear the singer or hear the bass or just keyboard and acoustic guitar etc. not headphones for a person sitting behind a desk. The ones you see band members putting their feet on all the time on the stage that can be moved around with a plug going to them. The audiobox has just a left and right output going to mains capturing all the channels for playback. Let me know if I'm missing the obvious, please.

[@RecordingStudio9]

I see you have taken the concept to the next level with live recording and personal monitoring with floor wedge speakers. I think you will hit its limitation and the only option next is to invest in a StudioLive 32 digital mixer to make your life easy. Thanks for your comment.

Hi, I remember Asio4all worked with soundcards with WDM drivers, so this could be the reason of some issues for someone 😊

[@shawngrenaud]

Thanks for this video.

[@EnigmaState]

Hi, not sure if you can answer this one. I have a Behringer UMC1820 + an Behringer ADA8200. I also have a Presonus FireStudio Lightpipe which can support up to 4 x Behringer ADA8200. Can I link the UMC1820 Optical OUT to the Presonus OPTICAL IN for clock sync and then use 1 ADAT on the Behringer UMC1820 and then have 4 extra ADAT's connected to the Presonus? Basically in short i would have UMC1820 + ADAT unit. PLUS Presonus with 4 ADAT units. It would give me a total of 48 inputs (8 on UMC1820, 8 on ADAT, plus 4x8 inputs on the Presonus with connected ADATS) But this leads me to my 2nd question, can ASIO4ALL support up to 48 inputs?

[@RecordingStudio9]

That is a question I can't answer as I don't have the units. But if you already have them, you can certainly try it out. As to ADAT sync, since the UMC1820 does not support WORD clock, you will lose one ADAT input on the FireStudio, which will make the whole exercise pointless somewhat.

[@marquezvanroeschen5340]

thanks man, that was helpful!

[@RecordingStudio9]

[@guerraldo]

excellent very well explained, the only video that has understood the problem of synchronization, the only bad thing is that it is not applicable to cheaper interfaces like scarlet or the behringer umc 202, because the drivers of these do not have the option of syncronization or I'm wrong

[@7alken]

and BTW, if all you need is only synced multitrack input (forgeting all the driver embedded in fact software-defined frontend strips) then I am sure best bet is to clear any vendor specific drivers to the roots from your system, let the system (win/mac) to detect device as "generic usbaudio" and let the system driver work in native low latency mode (wdm on win, coreaudio on mac) AND having connected (the same) usb interface instances to SINGLE USB controller even through hubs (but, at last mile, the "multi-TT" usb20 hub controller is needed, which is probably not so common now... they are pricey, they are warmer or even hot, because they do more, they inject every full-speed 10Mbit stream input into 100Mbit high-speed uplink) ... plus, unfortunatelly, as usbaudio implementations use different comm methods ( sync / async / adaptive) on different devices, this is probably important too, so, if you want try this way also...

[@RecordingStudio9]

I will try and see, but some Audio interfaces won't work without drivers as they can be proprietary. Thanks for your comment

[@needsLITHIUM]

Both of these devices have wordclock, as do most others in this price bracket and higher. If you get an external wordclock controller, this then frees up your ADAT on both for use with external devices to add even more channels.

[@RecordingStudio9]

Yes, that is certainly the way, I'm also showing alternate methods where you don't have to spend extra money purchasing Word Clock units (they are not cheap). For less than the price of a Word Clock unit, you can purchase Behringer ADA8200 :)

[@needsLITHIUM]

RecordingStudio9.com yeah, the ada8200 would be easier and cheaper with a single interface, but if you already have 2 interfaces, getting a wordclock unit later on would allow you to double up on the behringer adat units for 32 channels of input. That would be a monster! Lol.

[@RecordingStudio9]

You may be able to use the SPDIF to sync the two interfaces and 2 ADAT? 😄

Super well done video and information. Question: I have Presonus Studio One 5 and would like to use my analog mixer going through one interface for tracking to the DAW, and on playback, I would like you use the Presonus StudioLive 32S mixer for monitoring. (I prefer recording through an analog mixer and using outboard compressors, external mic pres, etc)... So my question is: Can I use an 8 channel Focusrite interface (Focusrite Scarlett 18i20 Rackmount 18x20 USB Type-C) for my analog mixer going into the DAW (in my case StudioOne to record the tracks) and use the Presonus StudioLive Digital mixer for playback (and monitoring). Is there a method that would work for that particular setup? Thanks and great info on your video. Note: I have not bought the Focusrite interface yet, so hence the question before I commit and buy one. Thanks and your videos are always very well done..... Phil NYC Area

[@RecordingStudio9]

Yes you can record with Focusrite and playback on StudioLive as you mention. One note is that, you may want to select/enable only 1 or 2 stereo channels (or as few as you need) for playback to minimise load on your CPU.

[@uptownphotography]

This is such an excellent video. Watched it a few times. I want to bypass (not use) the internal interface of my Presonus StudioLive mixer (32S model) and only use the Presonus digital mixer as a CONTROL SURFACE for Studio One....As I plan to buy an Antelope Orion (32in and 32out) interface. I know you used to have Presonus StudioLive mixer... Question Please: Would you know, if I DO NOT use the built in Presonus Digital Mixer Interface, and only use an external interface, (Like The Antelope or similar) will the Presonus StudioLive mixer still be able to be used as a Control Surface for the Studio One software? If it does not work, unfortunately I will have to sell my Presonus 32S model...and buy a dedicated control surface. Hoping you might know. Thanks as always... Philip

[@RecordingStudio9]

Thanks for your comment. Yes, you should be able to use StudioLive as surface control and use another interface as your audio device (although an expensive one 🤔). You can also set StudioLive as direct audio interface bypassing the faders, all DAW inputs and outputs connected directly to the physical interface inputs and outputs.

[@uptownphotography]

@@RecordingStudio9 I appreciate your reply and information. If I use the Presonus StudioLive ONLY as a Control Surface (and only use an external interface like the Antelope Orion) will I still need to use the ASIO4ALL in order for the Studio One software to see (and select) the Orion?

[@arthuraraujo258]

Great video! You might have answered this already but I figured it'd make no harm to ask. I've got a Focusrite Scarlett 2i2 (2 inputs) and a friend of mine has another one. We'd like to use them together to home record a drumset, using 4 mics but, unfortunaltely, the Scarllet 2i2 has no ADAT nor SPDIF. Would that still be possible?? If not, we'd probably have to use only 2 mics or ~maybe~ two computers?

[@RecordingStudio9]

You can try using ASIO4ALL with no hardware sync like I explained, and might work for a short period. Or use 2 different DAW, each setup with one 2i2, in same PC, then import the other 2 and try to sync the tracks. Bit of work, but there is always a way :-)

[@arthuraraujo258]

Hi, great video. We did everything what you say in the video but out of the slave interface we can set that the in and out in our daw reason is corresponding but no sound. Do you know what can cause the problem... we are using the scarlett 18i20 3rd generation as the master and the umc behringer 18i20 as the slave. Also sometimes the asio program that we downloaded crash often... thanks in advance

[@MichaelGuy]

could I run a scarlet 2i2 while running my protools hdx system with the avid 192? I need that low latency the scarlet offers when tracking guitars!!!

[@alexeysmirnovguitar]

This is very helpful! Thank you. Have you ever tested WORD Clock Sinchronizarltion possibilities?

[@RecordingStudio9]

If both devices have WORD Clock, then this would not be an issue to sync them both.

Hello again...New question please. I just bought a guitar modeler pedal. I would like to record the modeler pedal direct using the USB out of the Modeler Pedal into my Laptop. Now, I monitor through my Presonus 32S digital mixer so that I have the mixer faders controlling the individual audio tracks. Question: Can I just plug the Modeler Pedal (vis USB) into my laptop using Studio One (5) DAW and still have the Presonus mixer monitor the tracks (with individual fader control) of the audio tracks...OR, will I still need the ASIO4All software? Thanks as always. Philip NYC area

[@RecordingStudio9]

Since you are joining two interfaces, you will need to Aggregate (MacOS) or use ASIO4ALL (Windows OS) to join the two devices. For reliability, set high buffer size, but this will add latency if you are recording and require direct monitoring.

[@HardKillaz]

Subbed Nice that you took enough time to make everything clear

[@jamiew.lacroix7055]

Awesome video, just a quick query. Can more than 2 interfaces be used?

[@RecordingStudio9]

Yes, but unless you have good CPU and/or set high buffer size, it will struggle.

Hi... I have two tascam us 16x08 but I was not able to combine both.. could you please help ...

[@RecordingStudio9]

The Tascam US16x08 does not support ADAT or SPDIF connections, so it's not possible as Master-Slave configuration. You might try just ASIO4ALL and see how it goes.

[@HEARTBEATZSTUDIO]

@@RecordingStudio9 ok let me try.. I try to aggregate but it shows as one device .. I never done asio.. I have no idea on that too..

Are you on MacOS or Windows? With MacOS, you don't need ASIO. If MacOS, I can't help you as I dont have a Mac.

[@MrDaystarMusic]

I have a PreSonus 2626 and Presonus DP88. I am green at the digital recording world so I need to know the science behind using them together. I am working with LOGIC PRO X as my DAW. The book shows Light Pipe going in and out of both units and a BNC cable connecting the two together. How does this work? Please note that I am an old school analog user going into three Tascam DA 8 Format. This is all very new to me.

[@RecordingStudio9]

The lightpipe carries the digital audio data and the BNC is the very stable sync clock. So if you have more than 2 devices, they all sync to the main clock generator to keep everything in sync.

[@THESAMMUSIC]

I have YAMAHA AG06 and plan to buy Steinberg UR22C, Can I use ASIO4ALL to drive both in Cubase/Nuendo at the same time for 4 input simultaneously? Thank you so much.

Yes you should be able to.

[@joaovictorsalles]

For example: I have a Saffire Pro 40 + adat It also has a Profire 2626 + adat ... Would I use as two interfaces together, plus the two adat? resulting in 32 channels? @I'm From Brazil

[@erkamau9629]

Is It possibile to Sync via spdif and using the spdif out of the slave unite to transport audio ? Thanks

[@RecordingStudio9]

Yes, same principle. I do have video on the topic as well.

[@limitisillusion7]

My Scarlett 18i8 only has an ADAT input. Could I use an ADAT output from another interface and connect it to the ADAT input of the Scarlett? Basically I'm asking if the lack of an ADAT out on the 18i8 keeps this from working. I don't currently have a second interface, but I need more recording channels. I did use ASIO4ALL to record a USB mic with my Scarlett 18i8 using Ableton and it did work. Still, I've never heard mixed results from this ASIO4ALL method with actual interfaces. Support doesn't seem to be guaranteed with any of the interfaces I'm looking at. Well I checked and you can choose ADAT as a clock source on the Scarlett so hopefully ASIO4ALL will do its part. Do you have any recommendations of interfaces with 8-48V XLR inputs? That Presonus you have is discontinued, and interfaces are pretty hard to find right now anyway. I've had a good experience with the Scarlett, so the 18i20 would probably be fine. I noticed the Scarlett Octopre is similar but cheaper. Are there any others in the 500$ or under category that compete with it? I don't know much about the technical specifications. Is buying used a bad idea?

[@RecordingStudio9]

Check for Behringer ADA8200 for added 8ch mic pre into ADAT of Scarlet.

[@limitisillusion7]

@@RecordingStudio9 That's much cheaper, thanks. I'm still a little confused though. Since my 18i8 only has an ADAT in, I would have to use the clock of the ADA8200, but it doesn't have a USB output. Would all the channels of the master (ADA8200) output via USB through the slave (18I8)? And if so, do they output as separate tracks assuming ASIO4ALL works correctly? Because it was my understanding that ASIO4ALL combined the USB input of both devices at a driver level and the ADAT connection was just for clock sync.

[@RecordingStudio9]

ADA8200 connect to your 18i8 via ADAT, no USB. The extra 8 inputs from ADA8200 will appear on 18i8 USB.

[@Gahttz]

What if both devices don't have adat?

[@RecordingStudio9]

Than the result will be whatever I already said in the video.

[@lebogangradebe4323]

I have two usb audio interfaces and none of them have an adat connector. The audio interfaces that I own is the native instruments Komplete audio 2 and I own two of them. For some reason pro tools does not recognize both it only recognize one even after using the Asio option. Can you please assist me in this situation.

[@RecordingStudio9]

Make sure you are selecting the ASIO4ALL as the driver and not the ASIO driver of NI, then select both interfaces in ASIO4ALL driver setup.

[@AdemolaAdeniyi]

Thanks sooooooooo much. You just saved a soul. You made it so so simple. I've watched some other videos but yours is very clear. I have a saffire pro 40 and a fast track pro bundled with Protool 9 MP, because I love pro tools and I would want to make the fast track pro my main. Though i have not tried it, but do you think making the fast track pro, (which in my opinion is lower in strenght compared with saffire pro 40) my main so that I can use the protools, might cause any issue? I intend to use the spdif, thats what d fast track pro has. Thanks gain. I really appreciate your work sir.

Hello, How would I daisy chain 3 interfaces?? Im using a focusrite 1st gen and its a slave to the UMC1820. Connected via ADAT. Now, my question is, I bought a ADA8200 because I want to leave my drums and synths ready to record all the time so I need more than 16 channels. Can I link the ADA to the UMC1820, that is linked to the FR 18i20???? do I need both ADAT cables connected from the UMC to the FR? if I leave as it is, I have no free ADAT in and out! How can I work around this!? I see no one asking this on other forums or comments. Im at a loss. It seems people are not connecting more than 2 interfaces or not needing more than 16 inputs or they spend 3k on an interface, which I cant do. How do I get what I have to get me to 24 inputs!? I was looking at some RME products and came across the RME Digiface USB which seems to be what would work for me? but its 400$......f** that.............

[@RecordingStudio9]

It’s not that people don’t want more than 16 inputs, it puts lot of demand on the cpu that it’s not practical. But, try this Watch this video on how to sync the UMC and FR via SPDIF link, who both units support, then connect ADA to FR or UMC for extra inputs. Again not sure your PC will be able to handle the demand. Combining Two Audio Interfaces Using ASIO4ALL using SPDIF as Clock Link kzbin.info/www/bejne/nmq9p5RjYraJjLM

What if one of the devices does not have an ADAT clock link? I am looking to input from my headrush pedal board via USB for recording but need to be able to output through my main audio device and not using any of it's inputs for recording at the same time.

Welcome

[@pqsk]

Is this a limitation of Windows? I bought my 1818vsl about 8 years ago and never had an issue connecting 16 inputs on my Mac via 1 usb 2 port. I'm just reimporting some songs from an old mixer from the late 90s (fostex fd8) because I'm hearing popping on the last import from years ago and wanted to make sure I'm doing the syncing right. In any case this is useful info

[@RecordingStudio9]

1818VSL has ADAT in/out so connecting an ADAT interface like the Behringer ADA8200 will use just one USB. This video is about connecting two USB interfaces with no ADAT on Windows. On a Mac OS, you can simply use Aggregate and works the same way.

[@pqsk]

Wow I wrote 2 comments and they disappeared. We'll just going to say thanks for the info. Learned something new.

Not sure what you mean. I don't delete comments and I have no comments in my "Held for review" inbox.

[@alainszyller615]

I don't understand why the only available Audio Interfaces with more than 8 inputs are necessarily Mixers ?

Rack size limitations. But, there is PreSonus StudioLive 16 rack version as entry level and high end converters from there with DB25 sockets.

Another option to consider as an alternative to ASIO4ALL is FlexASIO. Download at: github.com/dechamps/FlexASIO/releases/tag/flexasio-1.5

excelent video, now i understand how to use 2 interrfaces, but i have 1 question, what happend if im using 2 interfaces 1818vsl?¿

[@RecordingStudio9]

Yes you can, but you won't be able to use any VSL driver for any of them, since they will both go through the ASIO4ALL driver. But, not owning two of them, I cannot test and confirm.

[@fatihkocak1197]

Very usefull video. But i want to ask that if i have 2 identical devices, should i still bother about clock thing? I'm askin because i have maudio fasttrack usb which only have 2 mono inputs and i just need 1 more. I can find the same devices 2nd handed and very good price in my country. Since it didn't have the adat technology i don't want to spend my money if i will not be able to record 3 channels simultaniously without issue. Btw in my interface of the soundcard there is an option for sample rate. My plan is to connect and install 2 fasttracks and set their sample rate to the same and use the asio4all for merge them. Please tell me if i will face the issue which you are talking about in your video. Thanks in advance and i really find your video so usefull, so simple and very educating...

[@RecordingStudio9]

Thanks for watching. If you but two of the same watch, even digital ones, after 1 mouth, they will be out of sync. So the issue is the same. It may work for a short time, but they will go out of sync. ASIO4ALL will work fine with the playback of audio over multiple interfaces, as it's generating the clock, but for recording, the story is very much what I explain in the video. You are better of saving your money and purchasing one that has enough inputs you require.

[@fatihkocak1197]

RecordingStudio9.com thank you so much. Even it's bad news for me i'm still glad that you answered it very explaining. Btw i'm also making recordings and playing instrument atbthe same time and i suggest you to keep rockin everytime. Even if you know only a simple riff, the satisfaction is still so much different from audio engineering :)

[@danlaskowski]

Nice lesson. Any way to connect a FIREWIRE ONLY device to an ADAT ?

[@RecordingStudio9]

Which make and model? If no ADAT or SPDIF, then, technically/reliably you can't combine 2 audio interfaces.

[@drbob54409]

I have used a firewire MOTU 828mkII with Digital Performer on an old Mac computer for years. Just made the transition to Cubase 9 Pro on a Windows 10 computer, with a Steinberg UR824 USB interface. Both of these interfaces have ADAT ins and outs (as well as wordclock). Can I route the inputs on the 828mkII via ADAT into the Steinberg UR824 and get 16 inputs for Cubase even though there is no firewire input on my Windows 10 computer?

[@nallrocky4619]

Hallo...if both ADA8000 and AD8200 are combined in parallel can you or no? using optical cable

[@nallrocky4619]

I have both, Behringer ADA8000 and Behringer ADA8200, I want to try paralleling so I want to have 16 input channels, 8 input x 2, can I think or not ???

[@RecordingStudio9]

Not that I'm aware of. The communication for ADA8000 or ADA8200 is to talk to a master controller like an Audio Interface.

[@7alken]

hi, you may be surprised, but I tested several years ago that what I thought even longer was finaly possible - to use usb20 high-speed multi-TT hubs to connect 8 discrete generic usbaudio 24/96 usbaudio codecs (some VIA chip) through 2 such multi-TT hubs to "single controller root" (thats important) usb sockets (or perhaps, yet another usb20 high speed regular hub, no need multi-tt at that layer, everything is already injected as high speed streams) ... and you know, as the whole beast is controlled from the sinngle main USB-controller in computer and it specifies exact buffer sizes and controls whole bus, then if you start sampling from all the channels (16 here) its all perfectly in sync at sample level, I predicted this (angrying probably many ""highend"" audio interfaces mfgs), then later I tried this, and it worked. howgh! :-) ... but now, prices of multitrack solutions over usb are uite ok, so no need to breakdance that much anymore :-) cheers

hi, Vatche, I happen to have several audio interfaces among them an old 1990 MODULE MOTU 828 firewire and it sincronises with ADATS and has the optical in and out and also the beringer fca1616 just like yours and I also have a PORTABLE DIGITAL STUDIO TASCAM2488 neo all of them have 8 ins and 8 aouts. Do you know if the ISO4ALL driver will make all of the modules work even if some of them are old modules. Thank you Vatche. God Bless you.

As far as I'm aware, as long as Windows recognises the device, ASIO4ALL can use it.

[@lawrencescotto]

I am combining two Focusrite Scarlett 18i20 interfaces. Will this create any conflict between the two devices of will it be an easier process?

[@RecordingStudio9]

If the driver detects two units and works, that would be great (let us know), otherwise, you can try this method. Possibly use the SPDIF as the clock sync to free up extra 16 inputs via the ADAT on each unit. kzbin.info/www/bejne/nmq9p5RjYraJjLM

[@BrettNoack]

You shouldn't need to use ASIO4ALL to do this, just the ASIO driver from whichever device you connect to the computer. The ins an outs will all show up in the DAW. You must however set one device as a master clock sync and one as a slave. In other words if you connect the the FCA1616 to the PC then set it to sync from adat, then the Presonus will be the master clock. At least that is how it usually works. It is best if all devices have Wordclock sync, then you can set one as master and have many slaves.

[@RecordingStudio9]

True only if you are on MacOS, not Windows OS.

[@BrettNoack]

@@RecordingStudio9 No... Macs don't even use ASIO.

[@RecordingStudio9]

@@BrettNoack That is what I just said. You said you don't need ASIO4ALL, and I said 'correct' if you are on MacOS. You can't have 2 different devices with different manufacturer drivers and expect them both to communicate via one driver. 90% of DAW can ONLY talk to one driver. So we use ASIO4ALL on Windows to combine them as one, where on MacOS, you can use the aggregate option to combine them. Hope that clears your confusion.

[@BrettNoack]

@@RecordingStudio9 And I said you DON'T need ASIO4ALL to connect two interfaces to a Windows PC. So long as they are connected via the ADAT optical connectors.
