Some comments, if you're interested: * The presets don't show up for any reason * If the default settings could be adjusted, it would give a more immediate start: ** Decrease Gain (! ;-) ** Decrease Delay ** Decrease amp release time * I noticed that parameter changes take a long time until these take effect. Even moving the pitch bend wheel did last some milliseconds until it was audible. Same when playing with the UI controls * Can it be switched to be polyphonic? OK, enough for today, it's bed time now :) . Thanks for the code and good night, ce
