notes on channel 13 and 14 get dropped because of an incorrect setting.
midi i/o page in the editor has Z: “cc 11”, and it needs to be on “MPE+ (’14 glitch and alias free)” if you want to run this preset with 12 note polyphony or less.
alternatively you can increase the polyphony setting to Base5+ (15).
if you notice any other presets with silent notes, this is likely the culprit. there’s at least one other preset that i can’t recall at the moment.
included the updated preset (otherwise unaltered) with correct Z setting to MPE+.
*did not notice this issue prior to latest firmware 2.3.14, but maybe it was there and i just never played this preset.
