first, it's not Qsynth you're doing, it's synthv1, as an LV2 instrument plugin.
second, MIDI instrument plugins can only be inserted to MIDI tracks (or buses) to have their functionality to the fullest (ie. driven by MIDI as input and audio as output; there's no use to ever insert a MIDI instrument plugin on an audio track.
and third, the audio output of MIDI instrument plugins appears on the first audio output bus, usually "Master Out", so to ear any sound you'll have to connect those output ports to the desired system playback ports of your sound device, speakers, headphones, whatever you have there to physically ear any sound ;)
all these are pretty basic as sure you will slap your forehead only this once and no more :)
