MIDI output does not seem to work

[philburk]

I connected an Arturia MicroBrute to the Macbook and ran:
./HMSL-OSX
I entered MIDI.SCOPE and was able to see ActiveSensing, PitchBend, and NoteOn messages.

I entered MIDI.TEST and expected to hear some notes play.
No notes played and no LEDs lit on the MicroBrute.

Hm, it's all working for me through Logic Pro X. I just set up a software synth channel and then hit record enable (listening on all ports), and MIDI.TEST successfully sent notes.

When you scan for midi devices in a DAW, do you see HMSL MIDI Source show up? I don't have any external MIDI devices lying around, but I can probably rustle one up to debug this. Currently, it's set up so that software has to specifically listen on the given port.

Try downloading the program SimpleSynth. After you start HMSL, you should see HMSL MIDI Source in the list of MIDI Sources for SimpleSynth, and MIDI.TEST should work there.

Currently this relies on the receiver to subscribe to HMSL's output stream. You could try using MidiPipe to route the HMSL stream to whatever destination you need. Eventually, when I get this going as an OSX application with a Preferences screen, I hope to have that functionality built-in.

I tried Logic Pro X with a Software Instrument. MIDI.TEST immediately worked. I then set up two tracks on different channels, enabled demultiplexing MIDI channels, and was able to record two MIDI tracks from HMSL into Logic.

I then tried SimpleSynth and it worked.

I tried to use MIDIPipe to route MIDI from HMSL to the Arturia MicroBrute and it did not work. No sign of MIDI passing through the MIDI Pipe. So I tried Bome MIDI Translator Pro and it worked great.

So MIDI output seems to work fine!
