Only "MIDI OUT" channels will actually play to the midi out (ie, channels you have inserted using the "Insert Channel -> Midi OUT" command. So you can't play midi out from say a TS404. If you're playing from a keyboard and hoping to have the result playing back to that keyboard (ie, using Fruity as a sequencer for an external synth), this is the only way to do it. HTH, G.
