wait, exporting to SMF1 will put each(qtractor) track on its own Mtrk, no matter they are on same channel or not, so it's not quite what you intend in first place.
but most probably SMF0 will do what you want:
1. switch View > Options... > MIDI > Capture / Export > File format to "SMF Format 0" (SMF0);
2. mute all tracks that are on any other channel than you don't want to merge/export;
3. go Track > Export Tracks > MIDI... as before (formerly option 2);
4. the exported .mid result file should have only data on the MIDI channel you want; also as a SMF0 the .mid file should have one and only one Mtrk;
hth.
cheers
