Triggering/Cycling the Envelope

1. Cycle Button — Press the button to toggle Cycle mode on/off. When this button is lit up, the envelope

will be free-running. In Cycle mode, the envelope will start on the ping clock (unless you gave an Async

trigger, see below... Pressing this button after an Async pulse will make the envelope re-sync.) As soon

as the button is pressed, the PEG calculates where in its cycle the envelope should be so that it ends on

the next ping clock, and starts outputting the envelope from this point. See Figure 3.

2. QNT jack (Quantized) — Apply a trigger/gate to this jack to cause an envelope to start on the next

ping clock. The PEG will wait for the next ping clock and then start the envelope. Holding a gate high

on this jack causes the envelope to repeat. See Figure 4. The rising edge of a trigger on this jack will

cause the envelope to re-sync if an Async pulse has previously been applied. The envelope will

complete at least one entire cycle even if the QNT jack goes low mid-way through the envelope.

3. Async jack (Asynchronous) — Apply a trigger/gate to this jack to cause an envelope to start

immediately. Holding a gate high will cause the envelope to sustain as long as the gate it high, and then

start the fall curve once the gate is released (A-S-R envelope). See Figure 5

4. "T" jack (Cycle Toggle) — When a gate is appled to this jack, both channel's Cycle buttons will toggle

state (on->off and off->on). When the gate is released they will revert to their previous state. The "T" jack

is useful for toggling between the two channels: set one channel in Cycle mode and the other channel to

non-cycling, and take the output from the OR jack (see Outputs section below). The "T" jack is also

useful for turning both channels on/off at the same time. Note: applying a gate to the "T" jack is the

same as pressing both Cycle buttons at the same time (whether pressing the button turns it on or off).

Thus, all features that apply to starting Cycle mode also apply to turning the Cycle button on using the

"T" jack.

Figure 3: Pressing Cycle button

When button is pressed, envelope starts outputting

instantly, from a point in its cycle such that it's in sync

with the divided ping clock. (Blue trace is cycle button)

Figure 5: Asynchronous trigger

Trigger causes an envelope to output immediately

(rising edge of trigger). Holding a high gate causes a

sustain period, and a fall period to begin after gate

goes low (ASR envelope). Envelope is re-triggerable.

Figure 4: Quantized QNT trigger

Applying a QNT trigger causes an envelope to output

at the next ping clock (ping clock not shown in figure).

Holding a gate high causes the envelope to repeat.
