VST Plugin Editor in Ableton

Hi guys,

I am in the process of making a VST editor for my Midi Synth. I have started by making an audio plugin that has MIDI in and out.

However if I put the plugin on a Midi track in Ableton I can not select a MIDI output anymore. It would be great if I can select my external synth in the plugin or as an output in live.

Any idea on best practices how to continue with this?

Any help is greatly appreciated!
