I have started keeping a look out for good deals on the parts to make my first Midi/PIC project a midibox64 with perhaps two cores for controlling Cubase2. Here is a link to an ebay action for 4x10k linear Alps faders, looks like 60mm (boooo).
The fellow has thousands of them, just wondering it they will work… just use one of the four gangs or heck, wire them up series/parallel and use all four.
