I have an early model Kurzweil MIDIBoard with V3 firmware for sale. I'm based in southern California, so you'd pay for packing and shipping if you can't come pick the unit up.

$400 plus shipping or best offer.

Also - I have a Kurzweil ExpressionMate allows you to add a breath controller input and ribbon controller to any MIDI synthesizer, along with a sophisticated MIDI processor and three independent arpeggiators.

The ribbon controller is 27.75 inches long and 1.5 inches wide. The actual control surace is about 22.5 inches. The MIDI controller unit is 8.5 x 4.75 x 2.5 inches.

This includes the ribbon controller, MIDI controller unit, power adapter, and a platform that the MIDI controller unit can sit on. The platform has a screw-on base so you can attach it to the top of a microphone stand. Or you can just velcro the unit to your keyboard if you have room.

$300 plus shipping or best offer.

Both units are in good condition, but have the usual scuffs and dings that you'd expect with them being in steady service for years (in a non-smoking studio). Thanks.
