Yes they are, basically everything is MIDI controllable in Qtractor
(mute, solo, panning, volume, plug-in parameters). Together with my
BCF2000 and BCR2000 it really is a powerful mixing tool. BCF2000 for the
mixing and BCR2000 for the plug-in parameters. I've programmed the
automation for the fade-out in seq24.

also, curious why you used Qtractor instead of Ardour?
are there params that aren't not able to be controlled in Ardour?
