If you are using the ASR10s sequencer only to create a set-up i.e. not actually recording onto the sequencer but channel x is program x, create your set-up so that channels 9- 16 (or 12?) have their midi parameter set to midi off, these track locations will then be muted (a.k.a. disabled) from sending or receiving any midi information. Again, this is if you have "midi off" available and your are addressing your software sequencer thru the sequence set-up section of the ASR10. If you would like to, e-mail me directly.
