Question about keyboards hooked up with Sonar

[The Legendary Zoltan]

I just started inputting midi into my sequencer, Sonar 3. After I input a piano part, for example, I record another track starting from the beginning. While recording in this way I can hear the first part (the piano part) playing back at the same time. However. If I change my new tracks patch to something like strings, one of two things happens. 1: If my inputs are MIDI OMNI, then the piano part also becomes strings, or 2: If I set the inputs to MIDI1 and MIDI2 I don't hear anything. Can someone help me make it so that I can record a strings part on track 2 while the piano part of track 1 is playing at the same time? Your help is greatly appreciated.

Leave the input on omni and check to see what the outputs for the two tracks are. If they're both outputting to the same place (for example, the same VST or ReWire device) try changing the MIDI channel of one of them -- this setting should be somewhere near the top of each mixer strip.

Thanks Moseph. This stuff is too complicated for my feeble mind. Hahaha.
