a bit off topic but can be fun to play with these vst synths :
I have half of those! Some great picks in there.
Is it simple to set those type programs up on
a RPi , then send midi messages to them ?
well if you install a windows os on a rpi maybe you will be able to use vst.
But is it possible to install windows on a rpi ? It seems to be that the official version is the windows IOT. But it seems to have another version : Windows 10 Desktop on a Raspberry Pi 4!!! - YouTube. Not sure you will get good performances…
For using vsts on linux, it’s possible but i have never tried. If you want to try : How to use Windows VST plugins on a Linux Raspberry PI - YouTube
