Is it possible to send MIDI from Matlab to a DAW?

2 views (last 30 days)
I wrote a small script to generate some random rhythms and output MIDI data from it, but I was wondering if there's a way to send this MIDI data into a DAW like Ableton. It works fine with the Windows GS Wavetable Synth and MIDI Mapper, but I can't figure out if it's possible to send it into the DAW. I don't have any external MIDI devices I can use as a passthrough or anything.

Generally the process would be to create a virtual MIDI port, send the MIDI messages from MATLAB to this port, and receive the messages in Abelton (or whichever DAW you prefer). If you haven't already, you will need to install a virtual MIDI driver (the one you choose will depend on your OS). Refer to the following pages for specifics on sending/receiving MIDI messages with MATLAB and an overview on MIDI devices with MATLAB

Thank you! I was thinking there was probably a program for virtual MIDI, since there's virtual audio cables.
For anyone else who might need this info:
I used this program to create the virtual MIDI port. Doesn't need any setup, just create a new port and it will show up in Ableton (and probably any other DAW). It functions as an input and an output so there's no need to make sure you get the right one when setting the mididevice() call.

You can work with MIDI using functions in Audio Toolbox. Here is the relevant documentation:
