Loading two EXI programs into one combi

[Rockitman]

I am trying to load two EXi program sounds into one combi.
A piano and a synth lead.
I put the piano on MIDI ch 1
The Synth on MIDI channel 2.
However the Synth on Midi channel 2 makes no sound.
Am I missing some setting? or can you not use two EXi sounds in a Combi?

Set the synth Program on MIDI channel 1 also, and both Programs will play simultaneously. Alternatively, leave the Combi as it is, connect an external keyboard's MIDI out to the Nautilus MIDI In, set that to MIDI channel 2, and play each timbre separately.

I just had a weird program that would not work in a combi. I do know the MIDI channels. I ended up usuing a different program.
