Waveform LEDS

The currently selected waveform is indicated by the two Waveform LEDs. LED 2 (pin 22) indicates

Tru-Foot, LED 1 (pin 12) indicates Sine, both off indicate Triangle, and both on indicate square wave.

It is also possible to use a red/green bi-color LED to indicate the waveform.

Note: The Waveform LED outputs are inverted on the module. As such, LED 1 (pin 12)

indicates Tru-Foot, LED 2 (pin 22) indicates Sine, both on indicate Triangle, and both off

indicate square wave.

Pots

Speed

(pin 2, pot0)

In Pot Mode (Clock LED off), the Speed pot adjusts the base LFO rate between 24 and 240

bpm. This range can be further adjusted using the Ratio control from 3 bpm to 960 bpm*.

* at very high bpm and extreme duty cycles, non-square waveforms can become

distorted

If a two or more taps are received, the tapped tempo will override the Speed pot.

The Speed pot and Tap button can change the Pot Mode output tempo while the chip is in

Clock Mode, however changes will not be apparent until the chip is switched to Pot Mode.

Ratio

(pin 3, pot1)

The Ratio pot multiplies or divides the LFO speed relative to the incoming clock (in Clock

Mode), or speed knob/tapped speed (in Pot Mode).

The Ratios are based on nine (9) musical subdivisions: two whole notes; whole note; half note;

half note triplet; quarter note (tap speed); quarter note triplet; 8th note; 8th note triplet; 16th

note. As a result, synchronized devices can oscillate at different yet complimentary rates.

The Ratio pot range is divided into nine (9) equal subdivisions, except the center quarter note

range is about 15% larger than the others.

Offset

(pin 4, pot2)

The Offset pot adjusts the waveform against the incoming clock with up to 360 degrees of

phase shift. The LFO can accent, syncopate, push the beat, or get right in the pocket.
