I don't have a TX816 but this question is more in regards to multi-part patches. When I load up the DX1 or DX5 patches between my DX7 and TX7, Patches 20 and 22 (E Piano 1A and E Piano 3A) I only get the B part; #21 works just fine. Looking at the settings, I can't see why it would just be completely silent for those two patches, there doesn't seem to be anything wrong with the levels.
Have any of you tried out these patches on your TX816? Any ideas?
Currently my favorite of this set are #1 Horn Section, #9 Cello 1, and #21 E Piano 2.
