hi rikki,
here is the setup: motif es rack as the sound generator for both the midi and my live playing (sounds way better than the SD imo)..so i am really just using the sd as a controller..when i play styles i use just the sd (if i had the time to properly setup the styles with Yamaha patches i would use it for them too!!!)...the problem is that all other keyboards i have played, they simply transmit the midi data that is within the midifile and add nothing else..the SD does...i have narrowed it down to something to do with the harmoniser...when you set controller 16-0 to force a track to drive the harmoniser (in my case, channel 15) it also glitches out channel 16 which is the channel i am using to play live keyboard thru the motif, BUT none of the other channels seem to be affected. channel 16 on the motif is then locked to some ghastly muted piano sound (i suspect it is losing a couple of samples within the voice) that cannot be changed by any further program changes unless the motif is reset....midi files without the 16-0 controller message play fine....btw when you remove all the channels in the midi (F6) tx options page, local off still does not work, it only works when you have channels 13 thru 16 activated...really weird stuff....as i said previously this is the strangest midi implementation i have encountered and i have been working with midi since the JX3P....i just needed to confirm if these things are happening on any other SD's or if it just mine..
cheers

PS, just wanted to add that i could solve all problems by just taking the laptop to gigs, but i want to use the HDD+sequencer capability of the SD its one of the reasons i bought it.If i am taking a computer i might just as well use a true controller boardlike the 76 note studiologic or similar...
