I finally got a drum machine! Love this little thing (Korg Volca Beats). I’m using my audio trigger detector to set the tempo from the audio output of the Korg. It would be better if I did it another way, such as by analyzing the sync signal from the Korg (probably stepped-down or current-limited, and capacitively coupled). Don’t want to fry my iMac or interface audio input.
The Audulus setup is the White Key Scale Player, sans the drum loops. The white key module UI shrunk, but the module functionality is unchanged. Keyboard MIDI channel is 16. The LFO that produced the scaled threshold signal is further divided to produce an even slower LFO. The second LFO outputs is used to randomly sweep certain synth parameters to add some variability. You’ll notice that “pulse above threshold” synth’s decay parameter is modified by the first LFO that produces the pulse output, so that when the threshold is high and there are fewer neighboring pulses, the synth has longer decay.
Oh, and the 2nd loop generator is no longer the modified res drum.
This cruddy video shows the little beast in action, and demonstrates that I can’t hold a phone and do a simple pattern on the keyboard!
