Yes, the Midi out wire is a single wire to the headphone plug. All other inputs/outputs you mention would require additional circuitry and my goal was only ever to get Midi out working.

Since I have a Quadra, I need an extender card to bring the HD26 out to the rear of the case (like the ones made by “Reply corporation”) so I figure I’ll design my own extender that includes the game port and audio while I’m at it. You were never able to find the pin on the Vibra for MIDI-IN?
It does seems like there should still be a line-in and mic-in available on the Vibra, but those pins are unknown too?
To be clear, the headphone cable you added is just carrying the MIDI-OUT signal?

Hi Steve,
In the ‘Hydra’ Cable, the MIDI-Out pin is hard-wired and no good for actual MIDI devices. Therefore, when I soldered up my own DB-15 port, I wired the pin off the Vibra chip through to the MIDI out port on the joystick port.
From there, you connect a standard DB-15 to DIN-5 MIDI cable where MIDI-OUT is wired through to the ‘Out’ cable which is then plugged into the MIDI sequencer.

I’m currently on holidays, but can research your board when I get home. We can then work out what to do and if there’s an option for yours. If you already have a joystick port on-board, then the re-wiring will be very difficult.. but it could be done if we get a male+female DB-15 and skip the on-board wire, providing the MIDI signal alternately.

I’ll send you an email now and follow up in a week or two.

Steven.

Can you provide a bit more info on the final steps, e.g. how did you go from having a wire coming from the vibra chip to using a 3.5mm mono audio jack to having a connector that connects to your SC-88 midi connection?

I’m wondering two things: 1. do the pins for my joystick port match yours, I guess I’d have test with a volt meter on pin 12 to see. 2. If everything is essentially the same, can you provide a bit more detail of how you went from the wire soldered on to pin 12 of the vibra chip to a connection you could hook up to your midi device.
