Recording external sounds from my triton

I am still having a issue with recording my triton sounds into my mpc.
I have midi hooked up , everything connected into a mixer. When making a sequence everthing is cool, I hear everything. When converted to song mode thats when i dont hear the triton sounds. Any advice is greatly appreciated.

So dont convert it to song mode....my rack does the same thing, everything will play on one sequence but if I put it in song mode with 2 or 3 sequences, the sounds get all messed up, it probably has something to do with the multi-timbral settings or something...
