How to fix Kurzweil Synthesizer PC4 SE not sending MIDI messages?
- Ooscar07Aug 19, 2025
If your Kurzweil PC4 SE is not sending MIDI messages to a computer or external MIDI device, ensure that the MIDI channel used by the PC4 SE matches the one used by the external device. In Global Mode, go to the MIDI page and set the Destination parameter to 'USB+MIDI+LOCAL'. If you're using a MIDI cable, verify it's plugged into the PC4 SE MIDI OUT port and the external MIDI device MIDI IN port. Also, check that the USB or MIDI cable is securely plugged in at both ends. If problems persist, try using a different USB or MIDI cable.
