the separate wave recording in MDrummer standalone does not seem to work. I've tried several ways to find out what's wrong on my side but nothing helped (i.e. assign channels to actually existing hardware outputs).
All I get is a master track with all sounds plus several empty (silent) tracks according to the # of channels I've set in MDrummer's mixer page.
Furthermore there's no sound on my speakers at all as soon as I choose the "Write separate WAV tracks" option. Upon disabling I hear the sound of the sum while recording (like it should be).
Any hint?
. Anyways I believe it is fine now in V12, are you on the beta list? If not, let me know and I'll add you.
