Qtractor without the tracks?

I would like to use Qtractor mainly as a plugin host and not as a ”sequencer”. I can do that using buses, but is it possible to use multiple tracks and have all of them producing sound simultaneously? This mode of operation must be possible without any user intervention, i.e. after program start incoming midi will trigger all defined tracks to produce audio output (no mouse or key actions required).

If that is not possible, is it possible to make the tracks pane ”invisible”? It occupies the majority of the program window and if not used I would like it not be shown.
