unfortunately i believe there’s no other way rather than sysex :frowning:
with a sysex message you can tell the machine to do specific things which you won’t be able to do with other type of MIDI messages (unless the machine you’re using allows you to) in this case reload a kit, which bear in mind,is not a feature you’ve direct access on the MnM (well, you can load the kit again but that’s not like it)
