Hi all,
I'm trying to make LS respond to a predetermined program change event
and unload all instruments across all instances as a result. So far
I've figured out I should modify EngineChannel::ExecuteProgramChange
to catch the special event and
call InstrumentManager::SetModeInBackground to have all the
instruments set to a mode where they will be immediately unloaded (I
forget which mode that is). How would I make sure this happens in all
instances since the program change event is only sent to one instance
of LS? My apologies if I'm using 'instance' incorrectly but I hope you
understand what I mean.
Background for the curious:
I have nicely organized large instrument maps for my giga instruments,
but of course memory is small in comparison to the amount needed for
these (though I wish I could load all 200 GB!). Many DAWs provide a
mechanism to deal with this, by allowing you to render the track and
temporarily unload all VST plugins for that track (I think the popular
Cubase calls this 'freezing', for example). Unfortunately, my DAW
doesn't know how to achieve this while respecting LinuxSampler's
unique design, resulting in a crash. However, I've discovered if I
change the mode of all instruments to the correct mode, then
LinuxSampler may be successfully temporarily unloaded and later loaded
again regardless of how many instruments were loaded. I'm trying to
automate this task, as it is rather cumbersome to manually change the
Instrument Mode for all instruments before and after every unload/load
cycle.

I have the same issue. I will be watching for developer responses and
will help out if I can.
Thanks!
