There are six parameters in System Mode. Tapping the 

Cycle 

button will advance the parameter, 

looping around to the first after the sixth. Tapping the 

Ping 

button will change the parameter value. 

1. Trigger Jack Function: 

The 

EOF 

light will be on, and the 

ENV OUT 

light will be red.

 

The color of the 

Ping

 button shows the 

function of the 

Trigger 

jack. Press the 

Ping

 button to toggle. 

2. Cycle Jack Function: 

The 

Cycle 

button will be flashing and all other lights will be off.

 

The color of the 

Cycle

 button shows the 

function of the 

Cycle 

jack. When it’s set to Gate toggle, cycling will be toggled by a gate on the jack. 

When it’s set to Trigger toggle, each trigger will toggle cycling. Entering 

Sync 

mode upon receiving a 

gate is also an option (See Sync and Async Modes section). Press the 

Ping

 button to toggle. 

3. EOF Jack Function: 

The 

EOF

 light will be on, the 

Ping 

button will be lit, and all other lights will be off. The color of the 

Ping

 

button shows the function of the 

EOF 

jack. Press the 

Ping

 button to change functions. 

4. EOF Jack Trig/Gate: 

The 

EOF 

light will flash/flicker. All other lights will be off except for 

Ping 

button. The color of the 

Ping

 

button and the pulse width of the 

EOF

 light shows whether the 

EOF 

jack outputs gates or triggers. 

When set to gates, the 

EOF

 light will flash equally on and off. When set to triggers, the 

EOF 

light will 

flicker briefly on. Press the 

Ping

 button to toggle. 

5. Free-running Ping: 

The 

Ping 

button

 

light will be flashing white or red. All other lights will be off. The 

Ping

 button shows 

whether the ping clock keeps running after an external clock patched into the 

Ping 

jack stops. Press 

the 

Ping

 button to toggle. 

6. Skew Limit: 

The 

ENV OUT 

light will be blue. All other lights will be off except for 

Cycle 

button. The color of the 

Cycle

 button shows whether the maximum slew time is limited. When slew is not limited, popping or 

clicking can be heard when using the 

Mini PEG

 with a VCA. Slew limiting prevents this by limiting the 

fastest rise or fall time. Skew is never limited if the envelope period is in the audio range. Press the 

Ping

 button to toggle.
