Best workflow for recording external synth as MIDI when ALSO using it as a MIDI controller.

Hey y'all, this one's a doozy but stay with me. I just picked up a prophet rev 2 synth and want to use it as both an external synth AND a MIDI controller for my software synths. On top of this, I want to be able to press record and record a MIDI region into Logic while hearing the prophet, not recording its audio yet, so I can edit and record the synth playing later. The problem I'm facing is this:

When using the External Instrument plug in OR the External MIDI channel (2 different ways of doing it), when I play a note on the prophet it plays TWO OF THE SAME NOTES:

1. Triggered by the prophet itself
2. Triggered by the External Instrument/MIDI Channel in logic sending MIDI to the prophet

This leads to that weird stacked/phasing sound you get when you have to of the same waveform playing at almost the same instant.

I can't figure out an easy way around this. The closest I've gotten is having an audio track set to the synth as input, and an external instrument track that sends MIDI to the prophet, takes the prophet audio as input, and outputs to stereo. In order to record how I like I have to:

1. Select the audio track, click the "I" to monitor it's input, turn on low latency mode.
2. Mute the ext. track and click its "R" button. So I can record MIDI here while monitoring the audio track, and presumably muting the track prevents it from sending the duplicate MIDI to the prophet. (Note that muting the non plugin version of external inst track does not prevent this)

Like this:

Then after recording the midi, to playback:

1. Unmute the ext. track
2. Unclick the R button on the ext. track
3. deselect the audio track or turn off monitoring

Like this:

So many steps and clicky clicks to remember. There has to be a better way. Any Logic/Hardware vets have a solution for me?

I think if the rev2 had separate settings for MIDI in/out channels I could do something but there's one MIDI in/out channel setting. I'm using MIDI over USB though and it does have separate MIDI In/Out ports, maybe there's something I could do with a MIDI interface but I'm unfamiliar with those.

Thanks in advance for your time and help.
