Play layered multiple voices from one midi channel

Hello Everyone !

I was wandering if it was possible to play two ( or more ) voices from the same keyboard from a unique midi channel ( let's say channel 1) .
I'm not talking about splitting, but more about layering.

It tried to add  "  MULTI_TIMBRALS = All   " to  my configuration.txt


and
Set,Channel,Prog,Voice,
0,0,0,1,#
0,1,0,2,#


to MTchannelmap.csv in the right folder ( 0 mysampleset )

But it didn't work ...

I don't really know if this is possible, but I'be great to do that in order to create more complex sounds.


Cheers !
