Strange, I thought it was 1 kit 1 patt when I used it... Have you tried assigning the pattern to a specific slot (eg h6) and then seeing what happens when it plays? I noticed the kit was just called new kit yesterday when playing the patch.
IMHO: I think C6 doesn't work as well as it should... So I'll try with a WIN XP computer and MIDIOX
Maybe a .SYX made with MIDIOX isn't compatible with C6? Really don't know since sysex is part of MIDI protocol which should be UNIVERSAL and machine-independent...
Any ideas?
@TIB: yes, tried SPECIFIC instead of ORIGINAL kit placement. THANK YOU!
