you create more buses. at least one more in addition to master which is
indeed stereo (2channels) and created by default ootb. you can setup
your workspace as with many ins and outs you need and make it a template
for all your future new blank/scratch sessions.

so, recipe is: create one additional bus, call it master_2 for instance
and assign it as input for audio track_2; audio track_1 stays on Master
for input. now you connect synth_1/outs to Master/ins and synth_2/outs
to master_2/ins. voilá :)

remember now that qtractor session templates may get very handy here,
for not having to be doing this all the time, as it also includes
connection recall. alas, it won't start your external synths
automatically, you'll have to do that manually, business as usual,
qtractor will wait for them appearing on the radar to reconnect. yep,
qtractor is not a full-blown session manager, i know. let's leave that
for someone else ;)
