miRack Legacy in Ableton - Midi out


I’m using the miRack legacy plugins in Ableton, and I can’t route midi out from it as it’s not possible with audio units in Ableton for some reason. For other plugins, I have to use the VST versions instead to get midi output.

Is there any workaround for this, or would it possible to get miRack Legacy VST versions for macOS?



I’ll have a look, I wasn’t aware of this limitation of audio units (or rather that VSTs can do it) in Ableton. A VST version is possible and this may be another reason to make it, if I can find time.

Thanks, it’s a strange limitation. I’m not sure if it’s just with Ableton or audio units in general.

When you route midi from a VST instead of AU, you get another option under pre/post fx in the dropdown menu.

Workaround for now is to load the patch on iOS and send midi with IDAM, but would be so much nicer to have it saved in the Ableton project!

I agree a VST version would be great.

Btw, it is a limitation of AU in general, unless they are specific ‘MIDI’ instruments like in Logic Pro X.


I found this. It really sucks that it is still this way, Apple.

They say IAC driver is the only solution to send MIDI to another plugin from an AU. I guess there might be latency issues.
