Here I want to introduce my approach to MIDIfication of the KORG PS3x00 series. It is not really different from previous solutions, but for me it has the advantage of being available when I need one.

The features:
– MIDI In only
– drives the 49 key contacts with the full voltage swing
– allows for program change in the PS3200 synthesizer
– has 8 1/4″ outputs, routed to an external breakout box featuring also the MIDI connector and a “learn” button to set parameters
– 6 of the analog outputs can be unipolar (0..+5V) or bipolar (-5..+5V) or a simple 0/+5V switching function and assigned to any MIDI CC
– 1 output is mapped to pitch bend with 14 bits of resolution
– 1 output is mapped to modulation

Here are some impressions of the prototype
