fact is, qtractor does call lv2plug.in->activate()/deactivate()
respectively, whenever its own plugin "activate"/"deactivate" commands
are issued, or the equivalent for other plugin types (vst, ladspa, dssi.
altough neither of which resets qtractor's external midi controllers
assignments per se...

however, depending on plugins implementation, it might (yeah might)
reset a plugins internal state re. their eventual midi control state,
leaving the host, qtractor in particular, to play catch-up after every
deactivate/activate() cycle...

yeah. you might have a point in there ;) maybe it's all qtractor fault,
of not having a separate "bypass" switch independent of plugins
(de)activate/activate() sort of power-cycle...

hmm... thinking of it, my recent "vee one" proto-toys (synthv1 &
samplv1) actually rest their midi control state upon lv2::(de)activate()
... that is, they behave as if a "panic" button has been issued
especially the all-controllers-off one (ie. GM CC#121) ...

so, should i read this whole question about a case of lv2 plugin
implementation or is that a lack of simple "bypass" on qtractor (or any
other lv2 host) to be at stake ?
