I am sure there are more patches like this out there, but just for reference I have uploaded it. So no fancy UI, sorry.
Essentially it is two synths that can be played via a midi keyboard like the Arturia Keystep. One is a rhythmic bass synth mapped to the lower half, the other one a FM lead synth mapped to the higher keys. A few parameters can be controlled via midi CC which you can see me manipulate with the Digitakt. Also the patch uses the Digitakt midi clock to sync bass synth rhythm and delay.

I swear I know that there are also white keys on the keyboard.
