Your first P.E.G. Patch: a Basic Walkthrough
Step 1: Prepare the PEG
•
Unplug all cables from the PEG, turn the Div/Mult, Skew, and Curve knobs to center (12 o'clock), turn
Scale all the way up, and make sure the Cycle and Bi-polar are off (not lit up).
•
Plug the "ENV" jack on the red channel into something you want to modulate — perhaps a filter, or the
pitch of an oscillator. Choose something simple so you can hear what's going on while you're learning
about the PEG.
Step 2: Set your Ping time
Before the PEG can generate an envelope, you need to supply a Ping time. The Ping time is the basic reference
that determines the timing of the envelope.
•
Tap the red channel Ping button two or three times, about a second between taps. It's easier to see
what's going on with a slow envelope. The white Ping button should be flashing at the tempo you
tapped. If you gave a third tap, the time between the taps will be averaged (unless the third tap occurs
more than 50% different than the timing period of the first two taps)
•
You also could run an external clock into the red Ping jack (when a gate is received on the Ping jack,
the internal tap tempo clock is stopped).
Step 3: Provide a trigger source
Like any envelope module, the PEG will produce an envelope when it receives a trigger. Also, like many
envelope modules, it can be set to self-trigger so that it'll cycle without any external trigger.
•
Press the red channel Cycle button (it will light up green). Notice the white LED above the ENV jack
starts flashing. The envelope is now running freely, in time with the ping clock. Adjust the other
module(s) you are running the PEG into so you can hear the modulation.
•
You also could turn Cycle off and run a manual trigger into the QNT or Async jack (e.g. try the Gate
output from a Pressure Points, or perhaps a clock output from an RCD/SCM)
Step 4: Adjust your output level
•
Adjust the Scale knob and/or play with the Bi-polar button to get a good voltage range that works well
with whatever you're modulating with the PEG.
That's the basic PEG patch: Ping, Trigger, and Output. Now we can play with the parameters of the envelope.
Step 5: Set up your Division/Multiplication amount
•
Turn the Ping Div/Mult knob to various settings and watch the Ping button flash faster and slower. Notice
how the tempo doesn't change gradually, but instead jumps from speed to speed. This is because each
speed is an integer multiple or division of the original tempo (e.g. three times as fast, or half as slow).
•
You also can modulate this parameter with the Div CV jack at the bottom.
Step 6: Adjust Skew and Curve
•
Fiddle with the Skew and Curve knobs to get an envelope shape you like. Notice the curve shapes in the
center section of the knob are all symmetrical (same rise and fall shape), while the shapes at the start
and end of the knob's range are asymmetrical (different curves for rise and fall). Of course, you can
modulate these parameters with the CV jacks at the bottom.
Step 7: Trigger the blue channel with the red channel
•
Now plug the red EOF (end-of-fall) jack into the blue Ping jack.
•
Turn the blue channel Cycle button On.
•
Run the blue channel "ENV" jack output to modulate something else. Set Scale and Bi-polar as desired.
Step 8: Modulate the blue channel with the red channel
•
Make sure the blue Ping Div/Mult knob is set to "=", and patch the red "+5V ENV" jack into the blue
channel's Div CV jack. Set the red channel Div/Mult knob to something slow. The blue channel should
speed up/slow down in time with the red channel's envelope.
Keep going, play with the "T" jack, try clocking both channels the same and hitting different triggers into the QNT
jacks... play with off-time triggers into the Async jack while the channel is in Cycle mode... modulate each
channel with the other, or themselves... etc etc! Have fun!
