It might sound redundant, but I suggest you play with it for a while without planning or adding anything. Adding a second VCO might be early now IMO.

Yes absolutely! It's super fun to play already. I just want to fully utilize the power of the Keystep Pro, this is where a second VCO would come in handy. Some drum modules would also be great or rather a drum machine to connect with the Keystep (still not sure what the better choice would be). But GAS is hitting me for sure thats why i plan ahead ^^
