Forgive my ignorance as I'm still getting familiarized with the ins and outs of older hardware.

Been trying to rig together a Pure Data/OPL 3 setup. Specifically, I have a bunch of weird generative midi patches in pure data, and I want to send the midi out to an OPL3 laptop triggering samples (could be through impulse tracker midi-in, openmpt, etc.)

I have a Libretto 50CT with a port replicator which offers these connections:

None of these connect to the MPU-401 midi interface inside, right? I've heard of people soldering directly to the MPU-401 chip but I don't know if I feel comfortable taking a soldering iron to this thing.

As an alternative, are there cheaper opl3 laptops (like a tecra 8000) that have a simpler midi-in option? Maybe someone can shed some light on how midi control input works on opl3 laptops in general.

Love u guys
