Can I use midi with FMOD in UE4 somehow?

Hi ,
Yes you can get access to the FMOD LowLevel API via the Studio API (ie Studio::System::getLowLevelSystem)

You can load a midi file as a stream using the low level createSound/Stream call.

You can also pass a low level sound as a source for a ‚Äėprogrammer sound‚Äô in studio, if you want to do things to the sound in an event.

So you can either

  1. play the sound with System::playSound
  2. pass the sound to the programmer sound callback, and trigger it as a sound in an event, which is a better workflow for sound designers.
