Hi,

Go to Setup/Midi Device Configuration and double click on the device you want to send to. In the dialogue box that comes up, uncheck Echo Midi Input To Output. That should get rid of your feedback problems.

Midi channel numbers have nothing to do with Voice numbers. To change the voice you wish to hear (instrument sound), click on the Speaker icon to the left of the track (in Window view) and select a new sound from the box. It's a General Midi list by default.

To change sounds within a piece of music, use the Sound Changes tab in the Main Palette to set a new sound by clicking in the place you want it.

Good luck.
