This is probably a very easy question, but after trying several things I couldn't solve it, so any help is appreciated.

I'm starting to use Realband for the first time and want to record different MIDI tracks. My MIDI controller is installed and works fine.
In the track view I can set different MIDI instruments and I can record on the tracks. But when they play back they play back the same instrument sound on both tracks even if the instruments are different. Likewise if I select each of the different MIDI tracks and play my MIDI controller I hear only one of the patches instead of the patch which corresponds to that track. It's like it can only process one sound at a time, which seems odd.

What am I doing wrong?

Thanks,

Zac
