This pair of videos, via Brandon Logic, demonstrate the Stochastic Instruments Stochastic Inspiration Generator, a sequencer module that responds to your probabilistic musical direction, starting with the fundamental musical atoms of pitch, duration, octave and articulation, and controlling how likely different variants will be in real time.
In the video above, four melodic voices are controlled by the Stochastic Inspiration Generator.
The second video, below, demonstrates capturing a sequence andn then manipulating the start and endpoints of the loop:
Each event the Stochastic Inspiration Generator creates has its pitch, octave, duration, onset, offset, portamento and ratchet set by probability controls. You can exert as much or as little control over what the next event will be as you wish.
