Max/MSP vs. PlanB Modular, Analog with Digital Control


YouTube via dkimcg

"I had read rumors of the MOTU 828MKII being able to send out low frequencies, low enough to be used as control voltages. So I had to try it to see if it works. Well, it does. The control signal is a little aliased, looks like a 8-16 bit signal. Not too steppy, fester than MIDI by far (but not precisxe for any real scale, need more tests to see how that is. But a very successful test to see if the MOTU 828MK2 could send out low frequency signals to control the modular synth without MIDI, a la VC. I patched together a simple little patch from the LFO tutorial on the Cycling 74 website (I'm a lazy ass programmer would would rather copy/paste). The 4 scopes on the left green side of the patch are the waveforms and clicks. The two waveforms on the scopes on the right are simple combinations of the 2 LFOs on the left. My camera sucks and the menus got overexposed. I'll cover what's going on in the annotations once again. I like watching videos for sound and music with no talking, so I make mine that way now that annotations are on youtube.

This is not meant to be a flex of my musical prowess or anything like that, just searching for interesting sounds, and testing out Max/MSP MOTU828MKII control of the PlanB modular.

Everyone who ever read those postings, but didn't want to shell out cash to test a theory, well, here's the proof it does, and now I have almost unlimited quick and dirty analog LFOs. At least good enough for almost unlimited 8 to 16 bit LFOs (that's about the resolution it looks, still better than an Arduino or other ATMEGA controller with a resister ladder DAC which is what I was going to try invstingating again next if this didn't work. It worked OK for teh theremin to Max before. Now on to integrating Max and the modular . Digital logic meets analog logic (Grenader & crew meets Zicarelli and crew). :)

I think one of my next MaxB tests will have to be making it stutter, afterall, isn't t a rule I have to make something stutter in real time as a Max user?"
