Pistons!

X-Keys Stick works brilliantly but... It was a real pain to fit and I'm still not completely happy with its position. Also the buttons are too close together and the feel is so light that it is easy to press a piston by accident! Better for gaming than a virtual organ!

So the plan is to use momentary push switches from Miyama Miyama DS-412. These seem to be the correct dimensions and can be obtained very cheaply. In the UK you can get them from Mouser Electronics.

I plan to use an mpc32xrs MIDI controller from MIDI Boutique to scan the switches and send note-on / note-off messages to Hauptwerk.

I plan to use the following layout, 10 generals, 6 divisionals, pedal coupler and clear and set on the great. Thats 25 switches.
