talk about these please.
nice to see another x0xb0x owner.
you assemble yours?
So the Mr grassi is one of Peter B's (ciat Lonbarde creator) 'paper circuits' from his site, made into a pcb and built by meng qi. It's a touch control chaos synth going from filthy bass tones to Superfast atonal arpeggios to bursts of noise....... The good thing is for all of its chaos it actually will do the same thing twice . Oh yeah it's two channel as well, with left and right being vastly different sounds, although somehow related enough to work as a massively stereo spread sound design tool! I love it, cheap as chips too.
The tetrax is similarly stereo but it comes out the right channel as you push down and left as you release on the barres. Each barre is its own osillator tunable by its sliders across two waveforms, two of the knobs are overall pitch for each wave shape and the other two are some sort of modulation chaos amount!
The patch points are for osc output, frequency modulation input, glitch in/out, cv's for press and release of barres, and cv control of knobs. Anything can patch to anything.
This thing can do insane bending pitch modulated rhythms (my favourite) all the way to crazy noise bursts like ive never heard in anything else. Recalling anything on this synth is pretty much impossible so recording everything of worth is a must!
The drone lab I built myself from a Casper kit years ago, 4 squarewave oscillators that can be amplitude modulated against a clock that emits a pulse wave, you can set the up and down portions of the pulse with the division knobs and invert that with a switch, so it's like they tremolo in sync with each other. The filter on this thing is gnarly as hell, and can get quite formant-y.
Favourite thing to do is set up a mega low pitch bass rhythm and put through copilotfx molecule for crazy rhythmic filter madness! Using the fine tune pitch knobs on each oscillator can make the rhythms bend around nicely!
I'll try do some demos soon and post here.
