I had a lot of fun and thought: well, why not try?
I took the M-AUDIO Keystation Mini 32 that I usually use for tests on the sets I produce (see attachment) and ... here is the result! :-)))
The only problem is that I couldn't use all 32 keys because the extension of the sopranos in the Costa Serina organ is only 30 notes, C3-F5 - I don't even know if I modulated with all the keys, but for sure I used only one stop ... it's not April 1st, but ... I just couldn't wait! :-)
Flutta soprani 8 Ft, solo.
Just for fun!
