- each Qsynth engine presents you with a separate and unique MIDI input port;
- you don't connect MIDI channels, you do connect MIDI ports instead;
- each MIDI port transmits or receives messages for all and any of the 16 MIDI channels;
- remember: a MIDI channel is just a number or tag on a MIDI message that is transmitted from an output port trough an input port;
- each MIDI channel is logically auto-assigned to each Qsynth engine instrument slot resp. on a one-to-one basis. (exactly 16 slots as seen in Qsynth > Channels window, one for each MIDI channel number resp.);
you just have to connect (possibly via QjackCtl) the MIDI device or application that emits or produces MIDI notes or messages (as source) to the desired Qsynth engine MIDI input port (as target); the soundfont instrument that will be played back is exactly the one that is the respective instrument slot assigned to MIDI channel being transmitted.
you may tell which MIDI channel that is being transmitted only at the source device or appliance (nb. it it's a MIDI keyboard controller for instance then it's usually configured to emit on MIDI channel 1 as default but can be anything else if setup properly).
