Can I create Players inside a Combinator?

Yes, you can!

First, however, you have to create an Instrument device in the Combinator that you could attach the Player device(s) to.

Here’s an example of a Scales & Chords Player device attached to a Subtractor inside a Combinator:

Player in Combi

You can of course also attach Players to Combinator instrument devices, to control the entire Combinator.
