Hi mosrite 1,
It is impossible to find the Genesys 6-pedal foot controller now. However, you can easily buy the Behringer FCB1010 MIDI Footcontroller and program it to call up different arranger functions (e.g. start, fills, var A, B,...)
The bonus part is that the Behringer FCB1010 MIDI Footcontroller has 10 pedals; therefore, you have 4 extra pedals for 4 extra functions of your choice. In addition, you can program the Behringer FCB1010 MIDI Footcontroller to call up voice presets and memories (i.e. registrations) on the fly
