What do you mean by preset kit?
Right now, by default, the generated patterns sent to the RYTM have a pattern length of 64 and Change set to INF…I didn’t have enough space / time to add a UI component for this, but it’s coming. Is this what you mean?
Evolve also humanizes the velocity in a non-relative way… this means it will always humanize the velocity around a certain default velocity…so let’s say you create a pattern on the RYTM where every trig has a velocity of 10…if you send it to Collider, humanize it, and resend it, all those velocities will now be humanized around 100 (the default value). It completely ignores the fact that you originally sent it low velocity trigs. This is not ideal.
The volume drop you are experiencing is probably because of the fact that Evolve messes with velocity (it does not touch ANY sound parameters).
The next update will include options to humanize in RELATIVE / NON-RELATIVE ways, as well as options to show determine what Evolve is allowed to affect. It will also include a File Manager to save / load / rename Patterns, Projects, Kits, Tracks, MFX, Mixer settings etc.
