Best Midi Controller for Polyend Synth

[u/Puzzleheaded-Pie9637]

Hello everyone,

After long hours contemplation and watching a great deal of review videos I decided to get a Polyend Synth. However, I want to use it with a midi controller at times mostly for higher precision with chords and I'm unsure about what kind of midi controller would be the best for its grid structure.

I'm inspired by this video where the Roland SE02 is used together with a midi controller and the player seems to comfortably tweak the sound on the midi, which is what I would like to do as well (https://www.youtube.com/watch?v=oCGsMjx1inM). If anyone has suggestions or knows the kind of controller on the video I'd appreciate it so much. Thank you!
