what's the deal with track 10 when you have 16 tracks of mid

what's the deal with track 10 when you have 16 tracks of midi, i.e. track 1=midi out 1a, track 2 =midi out 2a, track 3=midi out 3a, etc. etc. until you have 16 tracks of midi outs on 16 channels (1a-16a). All tracks are set to transmit pgm changes and bank select is set to yes, all msb and lsb are both set 0 in every track. this is the way I have it set up normally but it seems that track 10 is sending a midi message changing the sound on track 1. It is sending a program change message out of 1a as soon as you hit play, changing what ever sound you had chosen to the first sound or instrument that is in your sound module or keyboards patch list. I also figured out that if change the msb to 1 in track 10 it stops. I was wondering has anyone else noticed this or am I just doing something wrong?

is ur midi out 10a and 1a connectected to the same device?

yes and it is set to receive multiple channels of midi

I had similar problems with my drum sound module, a few things you should try,

if you can, set the sound module of midi out 1a and 10a NOT to recieve any program changes.

or

check in seqence edit under PRG CHANGE and see if there and program change notes in your sequence going out of ANY midi outs and if so delete them and see if that fixes it,

It might be that you 2500 is recording the PRG CHANGE event and thats why it does when you play back

anyways tell me how u get on.
