This works because most older Roland equipment sends an "Omni Off" message on power up. So here it is sending the message to itself. JX-3P test Modes: It's been a few years (10) since I had one: If you hold down the 1 button while powering up you are actually entering a test mode. The first 6 LEDs come on to show which of the 6 voices you are playing. If 1 voice was bad the service person could quickly determine which voice needs repair. Also, there was a way to enter test mode with rotating (hold down 1) or numbered (hold down 2, I think) voice assignment. Regards, Mike.
