Honestly, the best way to control these things IMHO is with your window manager. I happen to use a great "tiler" called i3 and have tweaked my configs in order to drive my work flow the way I want it. I'll include the magic below and will elaborate as needed based on any responses
for_window [class="(?i)Qtractor" title="Mixer"] floating disable
for_window [class="(?i)Qtractor" title="^Calf*"] floating enable
assign [class="(?i)carla" instance="(?i)Carla2"] $ws5
assign [class="(?i)Qtractor" title="Mixer"] $ws3
assign [class="(?i)Qtractor" title="^Aux Send*"] $ws3
assign [class="(?i)Qtractor" title="^Calf*"] $ws3
# This has to be last
assign [class="(?i)Qtractor" title="(?i)Qtractor"] $ws4
