Unfortunately Abby DIDN'T have any other choices, given his location and time requirements. He had auditioned the Genos several times previously and never did like it much. Apparently he still doesn't. I tried for a full day and didn't like it that much either.
As to backup...it's easy to have MP3s, midi files, etc., on laptop, tablet, phone...
I have two reasons for playing everything in stereo. First, because it sounds way better, second because I always have a backup p.a. with me. If the mixer were to go out, I can run directly into the various inputs on one of the Mauis. If one of them goes out, I can use the other one.
All the Genos owners over at PSR Tutorial are getting upset because someone has the gall to actually criticize the keyboard for which they paid so much money.
It's just gear. One size doesn't fit all.
