The first and last channels of the QSC feature a voltage-controllable panpot, just like the C channel. However, by combining this feature with the pan/crossfade switch, you can obtain a voltage-controlled crossfader! In this patch, we demonstrate both behaviors with the same CV, a bipolar LFO coming from FALISTRI’s green generator.

  • 1 QSC
  • 1 BRENSO
  • 1 USTA (Optional)


    1. Patch two different sounds to the first QSC channel’s left and right inputs.
      (In this patch we used BRENSO’s Final output and the green triangle output set to flip sync.)
    2. Set the behavior to Crossfade as described in Pan/Crossfade #1.
    3. Patch another source to the fourth QSC channel’s left or right input.
      (We used FALISTRI in synth voice mode.)
    4. Set another FALISTRI’s generator to Loop and its time scale to Long to obtain an LFO.
    5. Patch its bipolar output to the 333 to duplicate it.
    6. Patch a copy to the first channel’s Pan/Crossfade CV input.
      (Here the LFO defines the blend of the two sound sources.)
    7. Patch another copy of the same LFO to the fourth channel’s Pan/Crossfade CV input.
      (Here the LFO controls the left/right balance of the mono source, since the switch is still set to Pan.)
      (When a CV is patched, the panpot acts as an offset. Since we are using an already bipolar LFO, we don’t need to make any adjustment.)
