I was just playing around with the 301 and imagining a unit to analyze the incoming CV w/ the modulation inputs and output a click/trig when the value changes. Some quantizers do this - when there is a abs(delta) > 0, they output a click. This could be useful in assessing the changes in a pitch sequence, for example.
Is this easy to implement on my own in LUA, or maybe there is something similar already?
