Yamaha portable triple foot pedal unit
damper / sustain

sostenuto

soft   

Super quality. Certainly not a cheap three pedal unit as supplied by generic brands.

This is a VERY rare Yamaha portable, three pedal unit.  You try and find another one!

For half-damper capable Yamaha keyboards and sequencer software. It can also serve as a standard pedal switch (for sustain, etc).

I have also used it with Pianoteq and Synthogy's Ivory II piano software.
It also worked on my Roland keyboards.

NOTE: This type of pedal unit is not just an on/off switch, you can use it as a continuous controllers/pedals as it has potentiometers built into each of the three pedals.

The potentiometers' travel has been limited at the Yamaha factory when it was made. 
If you want the full midi data range of 0-127, do as I did and set/calibrate this parameter in your midi sequencing software for each pedal.  It is for you to check if your particular software has the editing features.

Depending on your keyboard or sequencer you can assign any midi parameter to each pedal.

Overseas: P&P might be cheaper for your address.
Please ask for a price before BEFORE considering to buy.
