I discovered two bugs in Plug-in Host and Mini Plug-in Host modules with Expert Sleepers SilentWay VST plugin.
1. Very often there is a glitch when opening Silent Way interface by pressing "VIEW EDITOR" button. I see some plugin window borders and nothing else. OpenGL is on, because if I turn it off my performance lowers drastically. I tried it with OpenGL off also on three different machines - same result.
2. When I use SW Voice controller and starting to play rapidly I have all the kinds of weird distortion. My connections are:
1. hardware synth audio out to in 1L of mini plug-in host (for calibration)
2. outs 1L and 1R of mini plug-in host to AUX OUTS to Host 2L and 2R respectively (they are going to my ES-3 module, 2L to hw synth pitch CV and 2R to hw synth gate).
3. MIDI from Host is connected to mini plug-in host (this is the problem, I'm pretty sure).
I have a lot of experience with Expert Sleepers modules and set it up in several different hosts including VCV, so I'm pretty sure I'm doing all the connections right

I tried this on 3 different windows machines. All versions are latest. My soundcard is RME UFX, on second machine it's UA Apollo and on third it's Focusrite RED. Hardware synth - Boomstar 4075 (but I also tried it with Moog Sub 37 - same story).
