Thanks so much for your reply, Christopher!
I use the Rockmore fingering method for some songs, and for others I just change the shape of the entire hand and move within the field. It seems like some songs have a need for finer definition between notes, and other songs have more long glissandos and sweeping ranges.
For the songs where there's a lot more gliss and sweep, I found that I was leaving 3 fingers extended all the time and moving around like that in the field, LOL.
An example of one that requires fingering would be "Saints Go Marching In". Just can't play a song like that without the Rockmore fingering technique!
The real time octave switching is very cool! I wonder why Moog never tried something like that on the E-Pro??
Thanks again - I love your videos here on TW!
My best,
Jim
