Quad Pingable LFO (QPLFO)

The Quad Pingable LFO (QPLFO) is a compact, playable four-channel tap-tempo, clock-syncable LFO with variable skew and reset.

The QPLFO is designed to be useful in small portable systems that require maximum functionality in minimal space, as well as large systems that need maximum modulation sources.

Basic features:

  • Quad "pingable" LFO's -- frequency is set by time between pulses ("ping")
  • Each of the 4 channels is an independent LFO
  • Can produce a variety of waveshapes: "Pluck," to ramp-down, to triangle, to ramp-up, and all shapes in between
  • Channels can easily modulate, trigger, and reset each other for complex and slowly morphing outputs
  • Slowest period is about 71 minutes (0.0002 Hz), fastest speed is about 500Hz (marginal tracking up to 1kHz)
  • Tap tempo button is free-running (LFO runs indefinitely), but external clock/Ping is auto-stopping (LFO stops when external clock stops)

Controls and Jacks:

  • Tap tempo button ("Ping") for manually setting the tempo
  • Ping jack sets tempo with an external clock (any complex signal can be used as a clock)
  • On/mute button enables or mutes the output (latching button)
  • Skew knob and CV jack control the waveshape by altering the ratio between rise and fall timesReset jack restarts the LFO without changing the tempo (rising edge triggered)
    • At 0% Skew (0V of CV), the shape is a "plucky" near-expo curve
    • At 1% Skew (just over 0V of CV), the shape is ramp-down
    • At 50% Skew (about 5V of CV), the shape is a triangle
    • At 100% Skew (about 10V of CV), the shape is ramp-up
    • Skew knob provides offset to the incoming CV signal, so any range of CV is acceptable
  • OUT jack outputs either a 0 to 10V waveshape, or a -5V to +5V waveshape (jumper selectable)
  • LED flashes and dims to the signal on the OUT jack
  • Tap tempo button flashes to the internal tap-tempo clock or to incoming pulses on the Ping jack
  • On/Mute button lights up when channel is On

Advanced:

  • Ping and Reset inputs use comparators, so any waveshape can be used for triggering (audio waves, complex LFOs, even the QPLFO itself!)
    • Trim-pot on PCB allows for adjustment of comparator threshold value
  • "Fire-on-unmute" jumper per channel:
    • When this optional jumper is installed, pressing the On button to turn the channel on will reset the LFO.
    • If the jumper is not installed (factory default), pressing On will unmute the LFO without resetting (LFO runs in the background when muted)
  • Bipolar/Unipolar jumper:
    • Setting jumper to Bipolar makes the outputs -5V to +5V
    • Setting jumper to Unipolar makes the outputs 0V to +10V
    • One jumper controls all four channels
  • One-shot mode: Reset jack can be used to trigger a one-shot envelope if the external ping clock is stopped. See manual for detailed discussion
    • Floating Reset mode: Holding a high gate on Reset jack allows the waveshape to run freely without automatically re-syncing to the ping clock. A bare cable plugged into the jack causes a high gate
  • Connects to other modules using ribbon cables:
    • Outputs can connect to the 4ms VCA Matrix, or the 4ms SISM, the Circuit Abbey Intermix or the Toppobrillo Mixiplexer
    • Normalization of ping jacks can connect to the 4ms Quad Clock Distributor
