Is it possible to use only one layer(material sound/voice) at one channel in the performance mode, when sequencing a song in the sequencer? So that I can't use for example a performance sound which consists on 4 layers, the way it is? Because, when I select the patch for a track in the sequencer, the performance 1 and 2 patches doesn't sound right, there comes some GM voice instead of the 4layer perf. sound...

Help me please, I'm new with all these MIDI things!

Thank you!
