Beautiful instrument! Had no idea about the "whammy bar". I love that turtle shell design you reproduced too. No where is the saying "a picture is worth a thousand words" more relevant than in trying to recreate ancient instruments.
I'm a medieval/renaissance instrument lover from way back in my days playing in the music school's camerata - recorders, crumhorns and cornetto (started out as a trumpet player). I'm learning the duduk now. Great instrument! That's a couple thousand years old or more I think - known to make grown Armenian men cry (especially when I play it).
You going do up a performance? Do up a piece for that lyre and theremin and you'll be right back on topic.
As for the theremin sample library. I can control the modulation amount better - I was too tame in how I was drawing the CC controls. I think this is better - but not perfect as I can't seem to change the modulation rate under CC control. Could add a bit more dynamic phrasing too. But I think it's fine for my goal of giving someone an idea so they may want to play it.
