Ping and Tap Tempo

"Ping" is the core of the PEG: every aspect of the envelope relates back to the timing established by the ping

time. There are two ways to set the ping time:

1. Tap tempo button — tap the white "Ping" button at least twice to set the timing.

◦ It's easiest to tap a tempo with Ping Div/Mult set to "=". This is because the tap tempo clock

can be divided/multiplied just like the external Ping clock. For example, if you tap a tempo with

the Ping Div/Mult knob set to "x4", the Ping light will flash four times as fast as you tapped.

◦ Three taps will average. Two taps set the ping timing period. If you give a third tap, it will be

averaged with the first two taps, unless the timing period set by the third tap is widely different

than the first two taps (specifically, it must be more than half, and less than twice the timing

period set by the first two taps).

◦ When a gate is received on the Ping jack, the tap tempo clock is disabled. Try tapping a

fast tempo while you have a slow clock going into the Ping jack — the fast tempo will take effect

immediately, but will revert back to the slow tempo when a gate is received

◦ Hold the Ping button down for 2 seconds to clear the tempo. The light will go off and the

envelope will stop. You also can clear an externally generated ping if the external unit has

stopped sending pulses.

2. External Clock — plug a clock or manual trigger module into the Ping jack.

◦ Only the timing between the last two pulses is used to set the ping clock timing (no

averaging). Therefore you can plug in a manual trigger/gate module (such as the Pressure

Points) and just tap in two pulses: the ping clock will continue to run at that tempo even though

you're not providing any more trigger pulses.

◦ Tip: A quick way to keep both channels in sync is to mult/stack an incoming clock in both Ping

jacks. Alternatively, you can use a clock module with multiple outputs, such as the Rotating

Clock Divider or Shuffling Clock Multiplier. Or you can patch the EOF of one into the other.

◦ The Ping jack has no roll-off, but the main chip can process incoming clocks up to about 10kHz.

However it can only output cleanly up to about 1kHz (depending on your requirements for

"cleanly"). So you can divide a 10kHz clock down to 1.25kHz, but it will be dirty. When outputting

frequencies higher than 1kHz, the output will be unstable, noisy and glitchy, but responsive to

the input frequency. See Self-oscillation sample patch. Below the 1kHz threshold, the PEG can

be used as a rudimentary harmonizer (e.g. sub-octave generator). See Audio Harmonizer patch.

The maximum time of either envelope curve (rise or fall) is about 15 minutes, so the total envelope time can be

up to about 30 minutes.
