Is it impossible to have the samples in Mono instead of Stereo in Kontakt 5? I've been reading up manuals and Kontakt's tutorials but I can't seem to have it set up properly.
I don't know if this is what you're looking for, but if you could route each drum instrument to individual audio tracks, you could then switch the outgoing audio of each track to mono by a stereo to mono plugin like dfx monomaker(http://destroyfx.smartelectronix.com/extras/).
