Audio & MIDI Menu
Everything that applies to the whole device rather than to one plugin lives here: input gain, output volume, the global EQ, the clock source, and VU calibration. These settings sit outside your pedalboards, so they persist when you load a different board.
Open it from the Audio & MIDI icon in the LCD toolbar.
Input gain and output volume
While in the menu, Tweak2/3 control your pi-Stomp's input gain and output volume, respectively.
-
Input Gain sets how hot your instrument hits the converter. Set it by playing your loudest passage and backing off until the clipping LEDs stay out of the red.
-
Output Volume is the level going to the amp or front-of-house, and is almost always available via the Tweak3/Vol control on your pi-Stomp.
These values are stored in settings.yml.
pi-Stomp v2: Instead of exposing a software volume control, your hardware has a dual-gang rotary pot connected directly to the output jacks.
Global EQ
The iQAudioCodec's DAC has a built-in 5 band graphic equalizer you can use to affect all sound leaving your pi-Stomp's analog outputs. It costs no CPU whether it's switched on or off.
| Band | Type | Centre / cut-off at 48 kHz |
|---|---|---|
| Low | Low shelf | 87 Hz |
| L-Mid | Band-pass | 143 Hz |
| Mid | Band-pass | 628 Hz |
| H-Mid | Band-pass | 2596 Hz |
| High | High shelf | 9560 Hz |
Gain runs from −10.5 dB to +12 dB in 1.5 dB steps. Note that the frequencies are not user-editable and move with the sample rate; the table above is for 48 kHz. At 88.2 and 96 kHz, the EQ is unavailable due to hardware limitations.
For surgical work, or anything needing a specific Q, reach for a plugin — see the EQ editorial. Use this EQ for the broad "this room is boomy" correction you make once you hear the space.
Clock source
Sets what the device's tempo follows. See MIDI Implementation for the MIDI side.
| Source | Behaviour |
|---|---|
| Internal | The pi-Stomp keeps its own tempo. Tap tempo sets it |
| Ableton Link | Tempo is shared with any Link-enabled software or device on the network |
| MIDI Clock Slave | The pi-Stomp follows incoming MIDI clock |
MOD-UI owns the authoritative transport state; the LCD mirrors it, so a change made in either place shows up in the other.
VU calibration
Sets the reference the level meters are drawn against, so the on-screen metering matches what your converter is actually doing.
