We are using unRealbook to play our backing tracks. And they have click track in the left channel, and all the music in the right channel. So it would be nice to be able to have the metronome play in only left channel on the songs where we don’t have backing tracks. I can get around it by recording a lot of clicktracks in different tempos with click in the left channel... and use them. But the metronome in Unrealbook would be easyer...
