V-Combo VR-700: Single-Manual Organ Mode
Use the following procedure to play the V-Combo as a single manual organ, with the organ upper-manual sound across the entire keyboard.
1. Make sure that the SPLIT and LAYER buttons aren't lit.
2. Press the HARMONIC BAR ORGAN "ON" button so it lights.
Note: Since the entire keyboard now plays the upper-manual organ, press the HARMONIC BAR UPPER button so it lights and the LOWER button is turned off—this assigns the drawbars to the organ upper manual, which is what you’re hearing and playing.
