This permits using an 88-key keyboard in conjunction with a B-3 style organ emulation to control various parts of the organ.
One mode permits you to control the bass pedal keys with the left hand and the entire lower manual with the right hand.
Another mode permits you to control the bass pedal keys with the left hand and the entire upper manual with the right hand.
The third mode permits you to control the entire upper manual with the right hand and a portion of the lower manual with the left.
See the video below for a demo. BTW - the regular “Organ Re-Channelizing Rack” now has included the pedals transpositions mentioned in the videol
If you have any suggestions for improvements or additions, please let me know and I’ll add them and re-upload the file with the improvements.
Update - as per a suggestion (a noted frustration) from Corky mentioned down-thread, this rack now includes the ability to utilize the bottom three notes left over on the 88-key controller as black-key preset switches:
Bottom 3 Notes (A, Bb, B) to Lower Manual Black Key Presets
Bottom 3 Notes (A, Bb, B) to Upper Manual Black Key Presets
@Corky - Please let me know what you need to change (!) and also mention this in the massive Organ thread if you would!
