Voltage-Controlled LFO

BRENSO trigs USTA that controls BRENSO that… Ok, back from the beginning!⁠

We set the green oscillator to LFO and used its square output as a clock for our USTA sequencer.⁠

Then, we used the saw output to control the amplitude, but first, we added a positive offset with the 321, so that it would work only with positive voltages.⁠

Then, we used USTA to control BRENSO’s pitch, but…⁠ It sends “notes” to the LFO, too!⁠

As a result, the LFO/clock/envelope will become faster or slower with every new note of the sequence: high note=fast clock, low note=slow clock!⁠

Experiment with these unconventional uses of BRENSO and USTA and let us know your patch tips!⁠

INGREDIENTS

  • 1 USTA
  • 1 BRENSO
  • 1 CGM
  • 1 321

DIRECTIONS

  1. Set USTA’s clock to External (as showed in the Clock and Ratio technique).
  2. Set the Frequency Scale of BRENSO’s green oscillator to Low.
  3. Patch BRENSO’s green square output to USTA’s clock input.
  4. Patch BRENSO’s Final output to a CGM Channel input.
  5. Patch BRENSO’s green saw output to the input of a 321 section.
  6. Add some gain and a positive offset to make the sawtooth LFO unipolar.
  7. Patch the output of the 321 section to the CGM VCA CV input.
  8. Write a sequence on Track 1 CV A only.
  9. Patch Track 1 CV A output to BRENSO’s yellow v/oct input.
  10. Rotate the integrator knob clockwise.
