The 

ENV OUT 

and

 5V ENV 

lights show the current threshold. Each light can be one of five possible 

colors: off, blue, purple, red, white. Off is the lowest value and white is the highest value. There are 25 

possible values. The 

ENV OUT 

light is weighted more than the 

5V ENV 

light. 

The lowest threshold is represented by both lights being off. The next higher threshold value is when 

ENV OUT 

is off and 

5V ENV 

is blue. The highest value is when both lights are white. 

The module starts bootloader mode with the threshold near the middle of the range: both lights purple. 

Each time you press 

Cycle, 

the threshold will increase and the lights will change. Once you get to both 

lights being white (highest threshold), it will cycle back around to both lights being off (lowest threshold). 

If you have trouble loading a firmware file and have already tried a different device and checked your 

volume, then adjusting the threshold may help. The best approach is to try different values until you find 

one that works. 

Troubleshooting 

• Make sure the volume on your device and app are at 100%. 

• Try a different computer or device. 

• Do not use sophisticated playback software such as Ableton, as these can inadvertently alter the 

encoded audio. Use the most basic playback program available. 

• Adjust the threshold (see above) 

• If you have an oscilloscope or a way to view waveforms, compare the output of the 

EOF 

jack 

with the output of the computer or device. Adjust the threshold using the 

Cycle

 button until the 

pulses are similar (accounting for about 40

µ

s-80

µ

s of latency, and of course amplitude 

differences). 

• Use a line-to-Eurorack module, such as the 

Listen IO

, between the computer and the 

Mini PEG

Viewing the Firmware Version 

On power-up, the 

Mini PEG 

displays its firmware version by flashing two colors on the 

Ping 

button. 

The first color turns on immediately after power-up, then the light turns off for a moment and the second 

color turns on. As of this manual printing, the latest (and only) version number is 1.0. 

Red, then White = 1.0 

System Mode 

System Mode allows you to change the way the 

Mini PEG 

works. To enter System Mode, hold down 

the 

Cycle 

button for 3 seconds. When the lights flash to confirm entry into System Mode, release the 

button. 

You can exit System Mode at any time by holding down either the 

Ping 

button or the 

Cycle 

button for 3 

seconds. If you exit with the 

Cycle 

button, your changes will be active but will not be saved after you 

power down (the previous saved values will be restored). If you exit with the 

Ping 

button, your changes 

will be saved. 

If you enter System Mode with 

Cycle 

on, the envelope will continue to cycle while you remain in 

System Mode, but you will be unable to adjust its parameters. 

Saving the Clock Time and Cycle State 

The ping clock period and the state of the 

Cycle 

button can be saved so that the next time you power-

on, the 

Mini PEG 

will load the saved values. 

If you are using an external clock patched into the 

Ping 

jack or received over Clock Bus, the tempo of 

that clock will be saved. If you tapped a tempo on the 

Ping 

button, that tempo will be saved. In either 

case the tempo before 

Div/Mult

 is applied will be saved. 

Whether or not the module is cycling will also be saved. If the 

Cycle 

button is illuminated at the moment 

you enter System Mode, then the module will turn 

Cycle 

on when you next power-on.
