I haven’t found it to be the case that MIDI thru has to be disabled in Reaper, but otherwise you’re right, no Sysex in via the “input from plugin host” option. Things seem to be working quite well with my Vecoven 3.03 JX-10 otherwise, tracks automation very well, etc. Nice work! and thanks for this, too, before finding it I was casting a skeptical eye on MKS-70v… seems a bit, er, overpriced. Ctrlr is a great solution.
