Put this together. CC mappings for each engine. First page is organized by screen… second page is organized by CC number.
Edit: added link to spreadsheet version below you can copy and modify if you want to. Also added dark mode versions for myself so it wasn’t blinding to have them up on the screen at night.
Awesome work @inz1 - thank you so much! 
Does the engines use same CC across all Polyend Series?
No, on the Tracker+ / Mini you have to trigger the macros to make changes to the synth engines.
Their internal parameters are not exposed in any other way.
I’m actually not even sure if you can send MIDI CC into the Play!? 
This is exactly what I needed to see before considering the Synth.
Thank you for putting this together 
Sweet mother you are a legend 
Was about to undertake this so tyvm for sharing with the community and saving me an evening 
@synthdawg can you add that to the manual?
Now when these CC are exposed, then it is just about time before some makes a browser based editor 
Does anyone know the CC Mappings for Mixer and Effects? For me they don’t show up in Control Change Mapping.
Done. MIDI Mapping is in the MIDI Section. Update may not have been uploaded by the team yet.
Sadly, i don’t believe there are any yet. For me that would probably be one of the most useful sections to map so I could mix/automate etc the 3 engines with faders and program channel mutes into a m4l device like I did with the tracker.
Also sad the PMD’s Array parameter doesn’t have a CC. It does a sort of resonance tuning effect that would be rad to be able to precisely sequence/automate/modulate. You just can’t get precise enough with the knob to jump to the correct value you want precisely.
I created two wishes, one for midi control, and one for macro/modulation targets.
nice thanks! was going to get around to it myself. ill keep an eye out for voting.
