RTP-midi (or other network midi) in os9
« on: January 16, 2026, 04:53:37 PM »

Hi guys, I hope you can tolerate my noobishness!  In short, I want to get midi over LAN to a G3 pdq on 9.2.2 to run my Studio 5 LX.  RTP-midi is my preferred midi protocol.

I tried bridging built-in OSX midi and classic mode OMS on Tiger 10.4.11 first, but classic mode's instability scared me out of this approach.  Is there a more elegant way to achieve it?

I was thinking to run Tiger on the G4 and connecting the osx RTP-midi to some kind of software from the era that runs an antique network midi protocol, that can run on both osx and os9 - networking the os9 machine to the osx g4 with hopefully only 1 piece of software being stuck in classic mode emulation.  Is there a piece of software that would fill this niche?  I have looked into it without luck.  Other suggestions are of course welcome.

Thanks everyone!   -afro-

Hmmm… I read this three times and I decided you’re correct… “”noobishness” is a good word here.

I’m not at all sure just what you’re really trying to do here and more specifics would be extremely helpful to assist in imagining what it might take to actually accomplish whatever it is.

Until then, all I can do is lay out some reference points. Hopefully they won’t be too depressing:

* “some kind of software from the era that runs an antique network midi protocol, that can run on both osx and os9”

That statement is doing a LOT of work. Far too much since there is no such software in existence.
(woulda been nice) Also, AFAIK, there is no such thing as an “antique network MIDI protocol”
I get (or at least imagine) that you want that magic software to allow the PDQ to handle RTP and use its serial port to comm that to the Studio 5. I can almost guarantee that will not happen.

* The Studio 5 requires OMS to run. OMS runs on OS9. It never made it to OSX. (also woulda been nice)

*  Random thought 1: RTP should probably be your “preferred MIDI protocol” only if absolutely necessary to span a distance too far for a regular MIDI signal / cable to cover unless you have all RTP-capable computers or you’re just trying to get MIDI from a RTP-capable controller from say, a studio to to a sequencer in a control room or similar.

* Random thought 2: Depending on what you’re really wanting to achieve here, you might resort to something like a KissBox on the G3 end. Then you can just plug regular 5-pin MIDI into your S5.

Yes, I know what those damned things cost.

Come back with exactly what it is you need / want to do. That will help a lot.

RTP midi does not exist for OS9 until you write it, and as you already found out, midi does not work under classic enviroment conditions.

using a single mac mini with OSX as "translator" would normally be a good idea, but you will probably run into the problem that USB to RS232 adapters can not support clocking, so the interface might not work as expected.

 - the minimum OS for RTP MIDI is 10.4.x.

 - small RTP to DIN converter boxes start at USD 45, but they will have like 2 ports only.

 - if anyone knows how to operate old opcode gear with OSX, then it is gary

what about... using a mini PC with windows? which probably can serve both worlds.
