I operate a set-up on our Technics KN7000
I used the foot pedals from and old Organ [Farfisa ]
The Kn7000 has provision for 6 pedal controls { the K7 has over 40 different uses that can be asigned to whatever use you want to use them for. [ I don't know what provision the KN5000 for operationg switches ]
The pedals are very sensative as they are bassically just an ON / OFF switch
I did however remove the unwanted pedals and shortened the original pedals and fitted lighter springs that return the switch function-----works extremely well and all it cost was a din Plug and a meter of wiring.

Just another idea that may interest some.
