@Derek
I used a Logidy UMI 3 back when I was a OS X user,
@Jaime
It works fine as a midi device in both linux and os x. expression
pedal works fine too. very sturdy, it’s a bit noisy, but I’m happy with it.
Thanks for all the info, guys. This UMI3 looks great, I will forward the tip to my friend.
Cheers! Gilberto
