I don't understand how to program and use the keyswitch and MIDI-learn functions. Here is what I've tried:
- I transposed the keyboard one octave down, to reach the unassigned keys below B.
I loaded two sample sets in slot one and two.
In most cases, the little windows to the right of the slots showed the entry "OFF", but sometimes the first one showed "G8". Then I had to switch Manybass several times off and on.
Now I highlighted the first slot. In the MIDI-learn part of the GUI appeared "KeySW1" and "unassigned".
I clicked on learn.
I pressed a key on my keyboard, e.g. G0. Nothing happened. The keyswitch remained unassigned.
I tried al lot of other keys. The MIDI indicator lighted up, showing that MIDI notes were received.
I moved the pitch bend wheel and the mod wheel. The assign window now showed CC#7 or CC#1. However, I still could't change the sound sets.
I loaded a program with keyswitches. Now I could change between the slots, using the MIDI-notes displayed, but I could not program my own keyswitches.
What am I doing wrong?
