Autosampler on Raspberry PI / Samplerbox update

[@mr_floydst]

Thanks to my viewer Patrick who pointed out that in the meantime, you need to follow the PI update instructions found in pip.raspberrypi.com/categories/685-whitepapers-app-notes/documents/RP-003476-WP/Updating-Pi-firmware.pdf first before installing Samplerbox!

[@glennmeader626]

Thanks digging deeper into the world of SamplerBox to create this excellent video!

[@Klangraum]

Color LCD (first thought it was an OLED), 4 buttons and a HQ audio codec for €30? That's a real deal. 👍

[@mr_floydst]

Oh, absolutely! :-)

Happy Christmas Floyd!

[@mr_floydst]

Thank you very much - the same to you!

[@thefumigator]

Amazing content, this is like 2 in 1, first the sampler then the auto sampler. In my case I'm a bit new to sampling technology, not sure if these samplers among other, do play a single wav file chromatically (faster or slower depending on the note) or it has a set of wav files corresponding to each octave (which I can imagine this would sound better). Anyway, it's time for me to take a look at those future music CDs and DVDs plenty of samples I've never used. Thanks for the video.

[@mr_floydst]

Hi, thanks for watching! This will play samples chromatically. It's a "clever script" which reads a directory of samples and automatically creates zones on your keyboard. So if you only have one sample, that one sample will be used for the whole range of notes.

[@thefumigator]

@@mr_floydst nice to know, but isn't this lower quality on notes that are low or high, far away from the original wav note when it was recorded? 🙏 thank you

[@mr_floydst]

Absolutely! That's why apps like "autosampler" exist, they'll record notes spaced evenly to fill those "gaps".

[@The_artist_called_The_Engineer]

Thread necromancy I know but would it be possible to run minidexed in this setup?

[@mr_floydst]

Minidexed is a "bare metal" project, it's not running on linux. You need to exactly use the hardware required by the project to make it work.

[@Jonny-y4m]

You can run minidexed with the pirate audio hat.

[@RyanCara]

Hey thanks for doing this! Was keen for you to check out this version 😇

[@mr_floydst]

No problem 😊

[@absurdbird3556]

0:31 Does anyone know what midi controller that is? I've been looking for one that size for ages! It faintly says "DONNER" at the top (I think) but I still can't find it.

[@mr_floydst]

Donner N-25. I made a video on this some time ago. It's me new favourite small keyboard.

​@@mr_floydst Thank for the response, I managed to find it with some googling... £129 from their official site, reduced to £59.99, and then 40% off with a coupon code to 35.99! Could not miss that deal 😁

[@yellowamongus2735]

just purchased myself one of the headphone dac pirate audio boards. do you know if it's possible to add custom fonts to the display? would absolutely love to make it utilise a sharp, aliased pixel font

[@mr_floydst]

The display on the board is a standard display that will show whatever you tell it to show. So if you know which libraries to use, yes, it's possible. Start here: learn.pimoroni.com/article/getting-started-with-pirate-audio#what-s-on-the-boards

[@toolzshed]

Whoa a Pi sampler 🔥🤘🏽

[@mr_floydst]

Thanks for watching!

[@roloftilanus1933]

Hi Floyd, I have followed your (great) tutorial and have the Samplerbox with pirate audio running. The only thing is that is is taking up to a minute to boot. In your video it only takes seconds. (running on a PI4) Also what ever I enter in the network.txt it will not connect to my wifi network. (this is not a major issue for me) Are there some setting I'm missing that makes booting this long. Thanks, Rolof

[@mr_floydst]

Hi Rolof! Boot speed depends on the SD card you're using, and you could also try to disable system services not needed. In this video, I've sped up certain parts to make it more "watchable". I haven't tried Samplerbox with the latest Raspbian release yet. Your WiFi woes might stem from OS updates that Samplerbox doesn't know of...

[@homerdus9668]

oh yeah keep doing these inspiring videos

[@mr_floydst]

Will do! :)

[@GaraGaraVideo]

Hi, thanks for the video. I have a question sorry - my sequencer only has midi out. The midi usb cables I've seen state that they run on windows etc but not Linux. What kind of cable or adaptor do i need to connect my sequencer to the pi pls? Thanks again

[@mr_floydst]

Hi, if you're looking to connect the PI to your sequencer using 5pin MIDI cables, any of those cheap USB to 5pin adapters are going to work. They're all using the same chipset and Linux has a driver for that.

[@GaraGaraVideo]

Thanks so much for this video, I'm going to try my hand at Samplebox. First venture into pi. I would like to just it to trigger long samples, eg a 5min vocal, with one note. Eg hit a pad and have the whole sample play as a one-shot. Is this possible? My controller doesn't have latch. Is the default for samplebox for it to only play while a pad / key is pressed? Given I'm new to this, if anyone reasons could you please treat me like a baby in your reply! Not familiar with pi, python etc. Thanks so much again

[@mr_floydst]

Please take a look at the "definition.txt" you have to place in a sample folder. Each note can have a release sample (that will be played when you release a key) If you create a super short sample that plays when hitting a key and make the main sample the release sample, it should play uninterrupted from start to end ;-)

[@GaraGaraVideo]

@mr_floydst wow. Thanks so much. That sounds doable. I have just subbed to your channel. Thanks again

[@_P_M_]

This is really interesting stuff. Has anyone built something like this for the Yamaha OPL FM chip? Would be a good way to do some retro PC gaming and also some oddball sounds for recording.

[@mr_floydst]

Thanks for watching! I don't know if it's the chip you're looking for, but @kasser_synths has build a range of DIY synths based on Yamaha's FM chip sets.

[@hablalabiblia]

Hi there. Great video!!! Could you recommend another option to the Pirate Audio? They are not available in my region. Thanks in advance.

[@mr_floydst]

Hello! You can really use any type of audio interface and screen with this. It's just that you need to tweak some config scripts yourself, then. Please visit the project's homepage (link in video's description) to learn how to do that.

[@Maschinestorm]

It looks like a cool project. Still want to do a fluidsynth build.

[@mr_floydst]

Thanks for watching! Keep me updated when making progress. :-)

[@praveenfernando717]

it has a delay when changing patches. actually I'm using this for a midi octapad. like Alesis midi pad. and I want to change patches quickly without a delay because I'm playing drum or percussion using this. can I fix it. thank you

[@mr_floydst]

You should post this question on the creator's page. My guess is that loading a soundfont takes some time, and only one is held in memory at a time. So pressing the buttons discards the current and loads the next soundfont, which takes a second. Theoretically, the PI has enough RAM to preload the previous and next soundfonts on your SD card to swapping is instantaneous... But that would complicate the code, I think.

[@gameboyz7497]

amazing stuff

[@mr_floydst]

Thanks!

[@zwingelstein]

Bonjour, Merci beaucoup pour cette vidéo très instructive et pour tout ce que vous faites. Bravo ! Est-ce que la carte audio pirate peut fonctionner sans être relié au réseau ? Merci.

[@mr_floydst]

Hi, thank you very much! The "Pirate Audio" is just a sound card with a screen and buttons attached to it. You can use it offline and in any way you want. See forums.pimoroni.com/

[@zwingelstein]

@@mr_floydst Merci beaucoup pour cette précision. Bonne journée !

[@postamesta]

Great work mr Steinberg. It is possible to make a code for one of the four buttons (longpress) to shutdown the PI?

[@mr_floydst]

It should be possible. The software is written in python, which is relatively easily readable, so theoretically, you could add that yourself.

[@Digithalis]

haha..pirate audio modul :-) very nice samplerbox solution. Is the audio-out quality on pirate audio modul better than from raspberry-pi?

[@mr_floydst]

;-) Yes, it is. Low-volume sounds don't sound "fuzzy".

[@ikestoddard2458]

Which Pirate Audio module? There are at least 3!

[@mr_floydst]

It's the one I linked in the video's description, the one with the headphone jack.

[@glennmeader626]

All three work the same with this project. I use the line-out version. It sounds great.

[@mr_floydst]

The tiny speaker one is the least advisable, though. :)

[@cristobalbarrientos5377]

Hello, Floyd! forgive me, I am not getting this correctly, So, just connecting the keyboard to th Pi and running this autosampler script as you show, will "capture" the samples in the keyboard, without pressing a key? I have a studiologic digital piano and it's also a midi controller, will I be able to save the original samples of the keyboard? and how I choose wich voice to sample? :: confused :: thanks again for your channel!!

[@mr_floydst]

Hi, thanks for watching! Autosampler will do as advertised: It will capture a number of samples automatically. You can specify the length of the notes and the "distances" in semitones between each sample captured as well as velocities. Once the samples are created, you can e.g. create soundfonts from them. On Windows, there's Samplerobot for that, if you're more proficient in Windows.

[@cristobalbarrientos5377]

@@mr_floydst thanks! I'll give it a try!!

[@sandrainthesky1011]

Hanging notes in this software is bizarre! Maybe running status incompatibility? I have programmed a lot with Midi and note offs can be kept as part of a record of note on's and a circular buffer/interrupts should be able stop any problem. Perhaps the UART RX should be more integrated into the sample routines? It's a shame it does that.

[@mr_floydst]

Could be the PI3 which does not have enough CPU power to handle these amounts of data from SD (but as you said, that shouldn't be the case). PI4 should handle this software better, especially the chorus and reverb effects.

[@kirkanos771]

Why did i hear buffer under/over/run in this video while you are playing ?

[@mr_floydst]

Hi, thanks for watching! I said it in the video: I used the PI 3b, which can't handle more than one effect on top of sample playback. Use a PI 4 for better results.

[@kirkanos771]

@@mr_floydst Thanks for the clarification. I thought it was coming from the video itself but wasnt sure.

[@rominar.8958]

Do the FX presets remain after rebooting?

[@mr_floydst]

I'm sorry, at the moment, I've disassembled this box so I can't answer that. Perhaps my viewers can chime in?

[@GertBoers]

I see there are two versions of the Pirate Audio: one for phones and one for line out. Did you specifically choose phones? And why?

[@mr_floydst]

Thanks for watching, Gert! tbh, I just grabbed the one which was available at the time. :-) Headphone out seems like the most flexible option to me, though.

[@martingerken7094]

Hmm... the Pirate Audio HAT is available in various version (line, headphones, speaker...). I cannot find the line version in .de - anyone knows if the headphones version works with line-in equipment (at low gain setting)??

Hi Martin! I bought the headphone jack version and so far my audio interfaces and guitar pedals didn't blow up. ;-)

Anyone get this to work recently? I’m having trouble understanding what I’ve done incorrectly. My pi just boots to a white screen, nothing in the display, no sound. I used the raspberry pi imager to install the OS, copied all of the files listed, I’m using an official power supply any input would be appreciated!

[@mr_floydst]

Have you tried connecting a big screen to see if there are error messages?

[@homerdus9668]

Pirate Audio :( Thanks for the great video, only problem was that I ordered the device without realizing how much noise it make. Setup works and is easy to set-up as well as import samples, but its not device for recording clean sounds. Noise levels are too high. I decided to return the Pirate Audio and started using proper Usb converter audio device like Focusrite/Steinberg (I got UR22C no more toys)... I guess you moidified the recording as there is no noise. Would have saved the trouble in I would know this. Anyways was fun to play.

[@mr_floydst]

Hi Homer, thanks for watching! I'm sorry to hear this. My pi-audio board had no noise whatsoever (and if it had, I would have mentioned that). I guess you had a faulty one.

[@KiR_3d]

Hanging notes seems like some bug.

[@mr_floydst]

Yes indeed. Could also be the PI3 was overpowered by using reverb and chorus. IDK.

[@postamesta]

Uploaded some C64 sounds on the Samplerbox (C64 Synth deluxe by BPB & RR). This is the first result: kzbin.info/www/bejne/j5LZnpuHd7-sfas Linked your video in the description. Thanks a lot.

[@mikefellhauer3350]

If it's not a sampler, why call it as "Autosampler/Samplerbox"??? It's a "Sample PLAYER!!!!" A sampler is a device that allows you to capture audio from another device (usually analog input, but can be digital)!

[@mr_floydst]

Hi Mike, thanks for your feedback! I called my video like that because I "reported" on a project named Autosampler and a project named "Samplerbox". Why the authors called it like this, I don't know. But it is as it is. Autosampler is a sampler, though. It automatically samples your hardware synth, creating layered multisamples for use on other machines.

[@yellownoiseaudio]

@@mr_floydst I am the author of SamplerBox, and a (beta) version of it which also "records" like a real sampler exist :) Not public yet. One day maybe...
