Gui is perfectly usable, all settings are accessible.Only the Help & Credits tab makes the plugin crash.

Every lauch of an instance of SWAM takes approx 5 seconds, Wine spitting some fixmes about wininet that I didn't solve yet.When opening a project with multiple saxophones, wait times add up of course...

These VST instruments take ressource ! Don't forget, like I did, to switch the cpu scaling governor to "performance".On my fresh Arch install it defaulted to "on demand" resulting in xruns all over the place.Quick check with
Code:
cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
Next setting which dramatically helps lowering DSP load (value reported by jack_cpu_load or Cadence/Claudia) is enabling "Allow LiveFX multiprocessing" in Audio Preferences of Reaper itself.This cuts down the audio charge reported by jack in half !

I'm currently loading 4 tracks with an instance of SWAM on each one and it seems solid.DSP loads at 20% when the instruments play together, no xruns.I use a Presonus Audiobox USB at 32ms latency (512/48000)*3 which seems the best compromise for the time being.

I also tried with Airwave but it crashes Reaper from the start.Same with the 1.22 binary release of Linvst.
Carla-Rack in Reaper fails to load SWAM with a timeout error (however it works as a standalone host).

More tweaks are welcome to build that Penguin Big Band but basically, it works
Wininet seems to cause some problems with some plugins.

I think what happens is that when the help is selected some plugins try to do something over the net via wininet and Wines wininet has things missing so maybe a wininet dll override might help.

The makefiles with rt in their names should be able to get better latency.
