This modification makes your PDX-2000/2300 able to receive a MIDI IN signal and changes the platter speed to match notes played on a MIDI keyboard.


The mod is made to understand incoming MIDI signals. When activated it will overtake the control of the ±50% ultrapitch and change the value corresponding to the note played on a MIDI-keyboard. The ±10% is still in use and can be used to correct out of tune samples.

The mod can play 20 notes from C0-G1 where C1 is 0%. A switch is used to select between MIDI and regular use of the ultrapitch.
