Hi All.

Today, I sat down for the first time wih my P250 and my keyboard. I 
managed to record some patterns - base drums etc on different 
tracks.  I created a few different patterns and arranged them into a 
song. It plays back fine. Great! 

My problem is this. 

Once I've recorded some drums on tracks 1 & 2, I want to record bass 
on track 3.  Doing this in Logic Audio - no probs. What happened to 
me on the P2500 was that I didn't seem to be able to have a bass 
sound to *hear* as I recorded it, and still have the drums playing. 
IE - I seemed to be recording on midi channel 1 (drums).  Since I was 
using onee of the BTS (which had a bass section), I was able to 
achieve what I wanted - but for other stuff that I want to do - this 
seems to be a stumbling block for me.

The keyboard that I'm using is basically an electric piano with Midi 
out - not very sophisticated.

Any help much appreciated.

regards, Peter
