I use a Roland PK-5 MIDI pedal board which has only 13 keys. The octave of these 13 keys can be changed by pressing the Octave function key and depressing one of the 13 keys for the desired octave. This is not very useful during performance if I want to use the pedal board to control more than 13 keys because the change of octave requires interruption of keys. The pedal board is very useful for performing bass and sustaining high notes of strings.

Has anyone used any other pedal boards that have a dedicated one-touch octave function keys that allows easy octave changes during performance? Does anyone know if Fatar MP-117 has any configurable octave keys? Since Roland PK-5 can merge MIDI signals can I use 2 MIDI-chained PK-5s to achieve a 2-octave pedal board (any real 2-octave pedal board is prohibitly expensive, near US$2000, 2 PK-5s costs a little more than $700)?

Has anyone use Yamaha MFC-10 MIDI foot controller? Can two of its buttons be configured as "octave up" and "octave down" function keys to connect to PK-5 pedal board through MIDI to achieve what I wanted to do?
