MiSTer FPGA Forum

I have a keyboard controller which can transmit midi data over USB. If I want to use it to input musical notes on either Atari or Amiga cores, which port do I use? Just a regular USB port? Or the User Port?

I have not tried the Atari or Amiga cores but I remember plugging my midi/usb adapter in a USB port and not the user port. I don't think it even comes on if I plug it into the user port. I use a Roland UM-ONE

The other way around works fine for me. I connected USB to my keyboard's MIDI-in and games with General Midi soundtracks work correctly on AO486. I'd assume the other way should also function even though I didn't test that yet.

Apologies if this is tangential, but I can at least report easy success transmitting MIDI events over USB to those cores and AO486 using an M-Audio Axiom 25 controller. Though events generated by the cores are transmitted to external synths connected to its MIDI OUT connector, I'm still wondering if it's possible to pass events from its MIDI IN connector to those cores, e.g. for sysex dumps from the synths. Seems MiSTer defaults to the first ALSA MIDI device; any way to address others?

im gonna butt in here quick with maybe a bit offtopic but, would it be possible to connect the mister to a <i>real</i> atari st(e) via the midi ports to use the genmidi core as a synthesizer ? i been dreaming about a "synther fpga" box that holds all those synths from the 80s and 90s i could never afford with a few midi ports that can connect to an ST running cubase ...

Haven’t had the chance to unpack my midi controller yet. But will try plugging into a standard USB port, thanks all.
