"New from 4ms! QPLFO ships April 25, 2013!

The Quad Pingable LFO 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 times
* Reset jack restarts the LFO without changing the tempo (rising edge triggered)
* 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
