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?
