Found A Cool Technique for Novation Circuit + Deluge Users. (P-lock Sample Swap Elektron Style)
i just figured out you can switch each of the circuit's 4 drum part's samples, via midi CC!
So, that means you can set a deluge midi track to ch 10, assign gold knobs to cc8, cc18, cc44, cc50, and plock sample swaps, per-step, on Deluge's matrix! Very cool.
