Hi Bill,
I don't think PSR's or even a Tyros has the midi capabilities to do this.
On my psr1500 I couldn't find a way to isolate a single track from the rest of the style parts & set it to external.

ie I wanted my Ketron SD2 soundmodule to supply drum & percussion sounds & to use psr sounds for the rest of the style parts.

The only settings I could come up with was for the ketron to supply all the sounds for the style parts & psr sounds for melody & left hand voices.

I don't think psr's have the settings required to assign individual style tracks to internal/external.

If I'm wrong , luv to know how to go about it as my ketron module has far better percussion & drum sounds than my psr 1500.
Would also give me the oppotunity of using some of my softsynths to replace some of the psr sounds.

best wishes
Rikki

[B]If you can set the Tyros 2 drum track to output just midi notes, (A drum track is just a sequence track for drums) then by using a VST such as Battery 3, you will be able to have better quality drum samples that will match to the styles. (The Tyros 2 controls the sounds of the VST as if it was an internal drum kit)
