You are right, i’m sorry I didn’t catch this detail before editing.
Exquis is a controller, and it doesn’t produce sound by itself. But it comes with it’s own application, which embed VST and AU synth plugins, and it comes with a big pack of dedicated Surge XT presets.
If I follow your comment on the ROLI product without embedded equator, then I should remove Exquis from the list. (Done)
Is there a section on the forum which list the MPE controllers? 
No, there is no wiki post for “hardware controllers supporting MPE” on Poly Expression: no one has created it yet. Creating a wiki post on Discourse requires at least a trust level of 3 (Regular) unless configured differently by the server administrator.
I added a link for the Modal Carbon8 as their new website is now up and running. I removed Aoydo as they went out of business before managing to finish the Omega synths. I added the Waldorf M since a firmware update gave it MPE support. I added the Arturia Polybrute (a firmware update added MPE support) and Polybrute 12. I removed the UDO Super Gemini since MPE support has not actually been implemented in its firmware at this time. I updated the Black Corp entries to reflect the fact that original MK1 versions also supported MPE, and to add the existence of a MK2 Kijimi.
I removed Zynthian as an entry due to it not actually supporting MPE (yet):
Odd.
It runs several software synths that do support MPE. Or at least, multichannel MIDI with per-voice bend. (Dexed and Pianoteq jump to mind)
Are these signals blocked?
Edit
I guess that’s a dumb question.
Ableton Live filtered out multi-channel midi, prior to 11, despite running MP E synths. this isn’t a new phenomena.
I provided a reference under the quote as a citation.
We have the Axoloti Core in this list, but for completeness’ sake we should add Ksoloti Core as well (especially because MPE has been reworked in the current version of Ksoloti)
There are plans to add MPE generation/output to Ksoloti, but I am guessing when it is ready, it should also be added to the list “Controllers that support MPE?”
I have added it with the remark “MPE support work in progress”.
Sorry for being unclear. Receiving MPE and creating MPE-capable instruments is implemented (and updated). MPE output is work in progress.
Ah, sorry, makes sense. Removing the remark then. And we can move it once MPE output is available, understood.
Hi! Maybe I missed something, but I think several Korg synths deserve a mention, all these support input of polyAT and per-note release velocity:
Also, the wavestate and multi/poly support up to four-part multitimbral usage, and the modwave optionally in two-part arrangement. This is optional, you can set each layer to respect the global midi channel or use their own.
So, technically this is only about two forms of MPE and unfortunately not more, but they are near-infinitely modulate-able and one could also carefully program the synths to use other MPE params only for certain layers. So really, the potential for polyphonic expression is indeed quite impressive…
PolyAT is not part of MPE spec.
MPE uses channel at per channel.
I think release velocity is also still optional, though many implement it.
Ofc , this is not to say instruments with polyat are not expressive, just not mpe compatible.
Behringer Ub-xa support MPE, but seem to have hardwired CC74 to filter cutoff
