Use Old Mac As Midi Instrument?, How can I use these OS 8 soft synths Options

[Seth]

I have two BitHeadz soft synths (Retro AS-1 and Unity DS-1) on my old OS8 G3. BitHeadz is sadly no longer in business and so I've gotten used to the idea of never using these synths again. Recently, however, I fired up the old Mac to check some old equipment out. While I had it on, I played with the AS-1 and realized how much I enjoyed this synth. So, it got me thinking - is there a way to wire the old Mac into my MIDI set up such that it could be addressed as just another MIDI instrument. The old Mac uses OMS of course. Any thoughts? Any other ideas about how to access these instruments?

I've considered sampling my favorite AS-1 sounds but that's just too much work. I could also record tracks into DP as audio, export the audio files and load into DP on my new Mac. Also seems like too much work. Or I give up and find something equivalent that's compatible - suggestions on that?

Thanks for any advice.
