So it’s entirely possible however not all parameters are basic CC. Some are NRPN which are typically used for high resolution controls.
Have a look at this chart - https://fael-downloads-prod.focusrite.com/customer/prod/s3fs-public/novation/downloads/15733/circuit-mono-station-midi-parameters-v1.pdf
This details what parameters can be controlled and how. The CC(8) ones are NRPN and require 4 knobs to do 1 thing.
Someone did this for the BS2 a while ago (which is very similar to CMS)
Setting the NRPN is a bit tricky.
As a test I did PW which is just CC - on the AMP page set the first knob to 39 (it says MVOL LSB because that’s what Elektron labeled it - there’s a standard midi implementation chart here - https://www.midi.org/specifications-old/item/table-3-control-change-messages-data-bytes-2 which is the default. It doesn’t mean the synth has those parameters though). Next go over to the FLTR page and turn the first knob. If the CMS has square wave selected you should hear the pulse width changing when turning knob 1.
