Sometimes you can think of USTA’s gate outputs as a modulation source rather than just a stream of impulses to fire some envelopes.⁠

In this patch, we used them to clock SAPÈL’s yellow generator so that one new gate = one new random voltage. We also set the gates to the green color to create a denser rhythm on top of our melody.

  • 1 USTA
  • 1 BRENSO
  • 1 CGM (optional)


  1. Set up a basic sequence with USTA and BRENSO (see CV, Gate, Length).
  2. Patch BRENSO’s Final output to the CGM mixer.
  3. Select the gate b channel and set all the gates to Repeat mode (green stage color), then create a ratcheting pattern.
  4. Patch the gate B output to SAPÈL’s clock input.
  5. Patch SAPÈL’s S&H output to the wavefolder CV input and adjust the attenuator to taste.
    Then, you can experiment with different modulation targets.
