Just some info in case you have missed it:

The Linux repos include an app called "Bristol" which is a Synth Emulator for about 20+ classic synths (see link, below 1-its sourceforge main page and 2-its first Synth)

They can all be controlled via midi on both alsa and Jack if set up correctly.

Personally not a Synth player, I have still always been blown away by this program's possibilities.

May you enjoy it and beautiful music issue from yr of fingers,
