Furious Microtemporal Programmer / Sequencer


Published on Aug 30, 2015 Gerald Stevens


"Video showing the basic features of my touch keyboard, ribbon, and joystick controlled analog microtemporal programmer sequencer. It is a little complicated! Lots of Ken Stone CGS boards insides, with a hacked Arduino / Narbotic Midivox MIDI clock.
The microtemporal side (continuously variable note lengths) functions by comparing any analog waveform (a rising sawtooth for the easiest to understand) with 16 stacked, variable width (each knob in the bottom row) windowed comparators. The other useful custom feature is the four gated (i.e. "strobed") LM311 comparators that allow note by note muting across all four sequencer tracks. Really simple (just turn the knob to zero) to implement - probably has been done, but I haven't seen this before."
