@moogmusic pay this man to build courses for your products! thank you for once again helping me learn even more about one of my favorite synths

[@RobeMusic]

Thanks very much. greatly appreciated, glad to be of help

[@LukeLendrum]

This is a truly excellent deep dive. Please keep making videos like this if you love doing it, theyre great.

[@henningriez7655]

great effort! thanks for going through these delicate details we all care about!

[@nicolameloni]

This is really great, thanks so much for sharing your knowledge! 🙏🏻 Can't wait to see part two!

[@RobeMusic]

Thank you! I think it'll be fun

[@equinox_flower_]

Thank you for this. Matriarch was my first synth a couple years ago and although i've learned a ton from it and explored alot. There are still many mysteries to it and in depth videos like this help me a ton!

[@RobeMusic]

Great, glad to be of help…Matriarch is super deep…I learn something new almost every day playing it.

[@TheConair92]

Was looking exactly for a video like this! so glad to see it

[@RobeMusic]

Thanks very much

[@MusicZeroOne]

THIS is gold. Thanks, I've just got mine and this really helps. I need to watch it a few times as it's still a bit much, but your style and approach is top notch. Subbed for more filter goodness

[@RobeMusic]

Thank you very much

[@VincentCordel]

you’re wearing because your brain is too large to use a hat! thank you for sharing your knowledge to the less savy like me. it is challenging content like this which pushes me to dig deeper. massive thank you for your content 🎉

[@garygimmestad4272]

You just handed us the keys to the Moog filter kingdom! I confess to not fully comprehending the theoretical part (yet) but isolating the filter is a great learning gateway for the less synth-savvy user - like me! Thank you!! I'll be referring to this video often.

[@RobeMusic]

Glad to be of help!

[@geerhoar]

Really excited about this series!

[@RobeMusic]

Thank you! I think it'll be fun

[@positivebacteriaculture]

This is exactly the content I've been looking for. You got a sub!

[@RobeMusic]

Thanks very much!

[@sdshannon]

Ohhhhh baby I’m excited for this series!

[@RobeMusic]

Glad you find these helpful…never sure if anyone likes them or not. 2nd video will be posted Thursday evening.

[@karma133]

Love your work man.

[@RobeMusic]

Thank you, much appreciated

[@ManCalledMif]

great video. thanks for explaining. very helpful. understanding multiple mono mode is cool

[@RobeMusic]

Glad you like it. One of the bonuses of patching mono with 2 outputs is you keep stereo delay - can’t remember if I mentioned that in video

[@jansteinmuller]

thanks so much for this video, learned a lot!

[@RobeMusic]

thank you

[@lockyp204]

Brilliant thanks 👍😊

[@RobeMusic]

Thank you!

[@veasy]

Thank you for explaining. I've got a Matriarch as well and thought the filter was much better, but now, using the dead patch.... Also the 4 times same CV into all 4 oscillators is a great idea. And the little PWM offset for the classic Moog sounds was new to me. Very interesting!!

[@RobeMusic]

glad to be of help!

[@K00LD00D]

🔥🔥🔥

[@Stardust_Ziggy]

Regarding the filter feedback patch at 29:30 : you get a different result if you patch the output into one of the osc inputs, because the noise input will invert the wave coming in. Easy to check if you e.g. insert osc1 wave out into noise in and then mix them together. You will hear nothing.

[@RobeMusic]

thanks Ziggy! that’s very useful to know…there’s so many neat little secrets on the matriarch. built in inverter is a good one

[@justinkinter8651]

Thank you so much for this video, SUPER helpful for a new Matriarch owner such as myself. Just as a side note I wanted to point out that the mixer section itself might be responsible for messing with some of the erroneous frequencies you were getting with the white noise. It’s my understanding that if any of the knobs on the mixer are pushed past about halfway, that you begin to actually drive the overall signal and specifically it boosts the fundamental. Other than that, like as far as any extra filters are concerned, I have no idea what’s going on there, but the mixer itself has to have some effect on the noise you passed through it. Anyway, was thinking you might want to know that if you don’t already, thanks once again and I’m Def a subscriber now ;)

[@RobeMusic]

Hello Justin, Very happy to hear that you found the video helpful. and thanks for subscribing, that helps a lot! Yes, the mixer on the Matriarch is a lovely dirty little mixer, I find saturation starts even well before the half way mark. You are correct, the mixer may have added frequencies to the noise...i actually bypassed the mixer and did the test again, results were very similar so i cut it that part out of the video...those vids were getting SO long didn't want to bore people to death. But good catch, and thank you for pointing that out.

[@justinkinter8651]

@@RobeMusic thanks for the reply :) ive always felt like the saturation MUST HAVE to start before the halfway mark just by listening to it and the fullness it brings but this has always just been little more than a suspicion of mine and the fact the manual says halfway i never really gave it any other thought so its def good to have an expert clear that up haha. but yeah, probably like if not my favorite features of this synth, then its up there. i feel like so few people realize just how integral it is to achieve that sound that moog/moog modular instruments in general.have, and that this synth has in spades. Love to just run stuff through it, probably one of my all time favorite ways to saturate stuff ever so slightly. anyway, thanks for nerding out with me a little bit. Ever since COVID hit and I literally had to sell my over $60K+ vintage/modern synthesizer/studi setup due to financial difficulty i havent had anywhere near enough moments to do just that so it def brightens my day and brings a smile to my usually stress filled face haha

[@galenmenzel4786]

Great video! Really useful. What spectrum analyzer are you using?

[@RobeMusic]

thanks. I’m using fab filter q3 eq plugin as spectrum analyzer and most of the time just use the scope that is included with my daw (use studio one a lot)

[@jmwen1]

I wonder if the VCF 1 patch input is dc coupled with the patch input for VCF 2. Would that explain why VCF 1 controls both filters when patched? This would be similar to the dc coupling of the VCOs- if you patch in a pitch modulation to VCO1, it’ll carry over to the following VCOs.

[@RobeMusic]

Yes Justin, You are 100% correct...after doing the video I thought about it for a while. Makes sense to have VCF 1 and 2 dc coupled at the VCF 1 CV in patchpoint...then you can modulate both filters if you want....and of course it's in the manual as well (which i should have checked right away). I'm going to talk about that in part 2

[@triplebeam23]

Do you use FL studio? Great video .. extremely helpful

[@RobeMusic]

No I don’t use FL studio. Mainly Logic or Studio One….actually more and more with Studio one these days

[@sanskiii8139]

A really helpful video! I have a noob question though. I know you can use VCF 1 and 2 as stand-alone processors for external instruments. But I'm wondering if it is ever possible to use them to process audio signals coming from virtual instruments as well? Like is there a way to convert digital signals coming from a software instrument in a DAW session to analog signals that can then be fed into Matriarch and got processed by its filters? Thanks in advance!

[@RobeMusic]

Yes, it's possible and really easy to process audio with an external synth. I was going to cover that in the second video of the filter series....but there was just too much to cover and the videos are all pretty long already. (at the end there's a little teaser kzbin.info/www/bejne/jIvSmXaLocSZitE) There are many different ways to do it...some DAWS make it really easy...but any "pro" DAW will be able to do it. All you need is to take the audio out, plug in to your synth filter inputs and back in to DAW from filter outputs. Easiest way is to use an I/O plugin. If you want to use the filter to process a vst instrument in your DAW that can be a little trickier depending on what you want the filter to do (example...envelope trigger from VST instrument) but it's still doable. Hope that helps, I will be doing a video about processing audio with your synth in late June or July.

[@sanskiii8139]

@@RobeMusic Got it. Thank you so much!! You are a lifesaver! I haven't seen such detailed and well-explained content on Moog matriarch from anywhere else and I'm looking forward to your new video!
