Thanks for your detailed documents pjd.
I have some problems with why user voice, that I want to use for a separate bass-pedal. I want to put a split to the sounds on the pedals, so that the lowest notes from C to Eb sound as 8' voice, and from E and up it is 16' voice - just like a bass-guitar.
But I can't make this i YEM. But you gave me hope that it could be possible to make these bass-voices out of preset voices. I need more time to read your stuff to get sure not to destroy anything.
I wrote a letter (before christmas) to Yamaha about the missing possibility to change preset voice, but I never had an answer from them. I hope that YEM at some point in the future will be updated to version 3.0, where they build in the facility - but I'm afraid that my hope are not worth a penny.
I hope I understand you right, that it is possible - theoretical at least.
All the best - Flemming, Denmark
