Still hoping to earn a biscuit then. 
The Roland FP80 Documentation disagrees with you some. There is no way for you to hear the audio from a Dorico vst on that model of Roland. Not unless you plug an audio cable into that mic input. It doesn’t have an audio driver that you could somehow select over USB that Dorico could use for output.
Just trying to get you a solution.. Something is off here…
I’m not meaning to beat a dead horse. It just means that midi - not audio - was once going from Dorico to the Roland. We can make happen, but you would be replacing a vst with an external midi instrument in your project.
~~~~~~~~~
Please tolerate the ‘legnthiness’ of the following, as I am only trying to walk you through my process, with as much precision as I find possible.
I so appreciate your attention, and I seek to be very clear. I am new at the piano-midi audio Dorico vst ‘thingmebob’, but I am telling you what’s really happening, and has been so, since I started working in Dorico August 2024.
=> I never work in Dorico, while listening to its playback through headphones, plugged into the back of the iMac.
=> However, have always had an extension cord (mini plug) plugged into the iMac headphone port, just in case I would want to, for listening to Dorico tutorials.
=> my external headphones were always plugged into the mini piano keyboard, which would allow me to listen to my own playing, plus any score playback I submitted in Dorico
=> I choose not to use midi piano key note input at all. My technique is imprecise for realtime input. I would figure what I wanted to input, and always use mouse to Score in Dorico (far superior to a pencil and eraser).
=> The following describes exactly my process:
• notate in Dorico and playback to audition it
• The Dorico library of selected VST instruments/voices would play through my piano midi headphones (typically SATB voices, seleted as individual instruments, ie. Voice Soprano, Voice Alto, Voice Tenor, Voice Baritone, as well as Keyboard Piano, and Upright Bass (even with a jack resident in the iMac external headphone jack).
=> To turn on the Playback of scored notation, I would click on a note, and then press ‘p’ and all the selected VST ‘instruments’ would sound through the headphones plugged into the Roland FP 80 external Headphones, whether or not the midi piano’s sliding volume was set to 0 or high. Volume control would only be through the iMac Volume icon positioned on top banner of the screen.

nb * To check midi ‘functioning’, I have now downloaded to my iMac, MidiView (Midi Monitor).
The following is a test with Step by Step outline, I just carried out, in response to your last email (to assist you in your analysis, perhaps):
1a) Cold Boot up of iMac
1b) Turn On Roland midi Piano, run MidiView app, to confirm midi is recognized by iMac
1c) Turn Off the Roland midi piano and disconnect from a) the FP 80 and b) from the iMac cable plugs (each end)
-
Confirm through MidiView that the midi piano is no longer mapped into iMac
-
Open Dorico software
-
In Dorico Preferences:
Confirm Roland FP 80 no longer Displays in Preferences/Play/Midi Input Devices, and
Confirm in Preferences/Play/ Recording that the folliwing options are no longer selected: (enable midi input) (enable midi thru) (Filter out Midi Controllers) and click Apply and Close
5a) Shut Down the Dorico Software
5b) Shut Down the iMac
5c) Cold Boot iMac
5d) Reopen Dorico Software
5e) From top Banner :
Help/Create Dagnostic Report and submit and write time reported in iMac Desktop of report completion (11:37 am Sep 7)
5f) Shut Down Dorico Software
5g) Shut down iMac
-
With Midi ‘off’, reconnect Roland midi piano to the iMac
-
Turn on Roland midi keyboard and confirm with headphones in midi jack that midi keyboard piano sound occurs, and leave volume on ‘low’
8a) Cold boot iMac
8b) Run MidiView app to confirm midi is recognized by iMac
8c) l Boot up Dorico
9a) In Dorico Preferences/Play/Midi Input Devices/, ensure that the Roland midi is listed, as well as the new app MidiView
9b) add checks to midi Recording selections
and click ApplyClose
9c) confirm via iMac banner icon Sound, that External Headphones has been selected
9d) observe that a jack with no headphones is still resident in the iMac external headphones port
9d) Submit once again via Dorico banner Help / and confirm date and time of .zip file on the Desktop (12:03 Sep 7)

* I have never used external vst instruments
Save as ‘Sep7 Midi Headphones Test’
Mouse Notate on score a few bars
- Wearing headphones plugged into the midi piano, and setting the midi piano volume to 2/3 on, with jack in the iMac External Speaker port, submit Playback of the new score.
12a) Confirm:
=> if you hear output from the Dorico score
=> no output audible AT ALL on midi headphones
=> Output ONLY audible through iMac External Headphones
=> nb : with External Headphone Jack resident inMac port, and Device Control selection
changed to External Speakers, Output is audible through the Speakers and not thru keyboard headphones and also not audible via iMac External Headphones (note that a Jack had continually been resident un the iMac headphones port
Please note that I can only map to headphones if a Jack is resident in the iMac port. That’s exactly why I can tell you that the Dorico Playback used to come through the midi keyboard headphone jack.
12b) Create another Create Dorico Diagnostics with date and time for zip fole on Desktop ( Sep 7 1:03 pm )
I am attaching only the final "Diagnostic zip file because the process overwrites the previous zip file.
And the Dorico Score file.
Main issue is the Dorico playback no longer is audible, in any way, through the midi piano keyboard headset port.
I am sincerely attempting to save you time, but I apologize for the run on details. I also wanted them for my retention.
It used to work, i.e. Dorico playback through my Midi Piano External Headphones.
