Display Settings
Configure the OLED display and LED behaviour.
FUNC1 → Settings → Display Settings
| Setting | Range | Description |
|---|---|---|
| Gamma curve | 0.00–7.97 | Display gamma correction |
| Min brightness | 0–255 | Minimum LED pixel brightness |
| Max brightness | 0–255 | Maximum LED pixel brightness |
| Color theme | 0–4 | LED colour theme preset |
| Invert display | yes / no | Invert the OLED display colours |
| Button tester | — | Opens the interactive input debug screen |
| Overlay timeout | off / 1–30 s | Auto-dismiss overlay screens after this time |
| Live waveform | yes / no | Show the audio waveform on the idle screen. When on, hides the input/output meters and network indicator (they share the same screen area). |
| Func LEDs | on / off | Show the multi-zone signal level meter on FUNC1 (input) / FUNC2 (output) — see colour key below. Off by default. |
| Clip LEDs | on / off | Adds the magenta soft-clip-catching latch on top of the Func LEDs zone colours. Held briefly so transient peaks remain visible after the signal drops. Independent of Func LEDs. |
| Input meter | on / off | Vertical bar in the OLED header (left) — shows Audio Input track (Track 16) signal level only. Hidden when Live waveform is on. |
| Output meter | on / off | Vertical bar in the OLED header (right) — shows the combined level of synth tracks 1–15 only. Hidden when Live waveform is on. |
| Network ind. | on / off | Letter glyph in the OLED header: U = USB-NCM ready, W = WiFi station, A = WiFi access point, blank = network off. Hidden when Live waveform is on. |
Header indicators at a glance
The OLED header row shows live signal flow even when the sequencer is idle:
- Input meter (left bar) — fills top→down as Audio Input audio arrives at Track 16. Solid block + zone-coloured FUNC1 LED.
- Output meter (right bar) — fills bottom→up with the combined bus level of synth tracks. Solid block + zone-coloured FUNC2 LED.
- Network indicator — single character showing what’s currently serving the WebUI / REST API.
FUNC clip LEDs — multi-zone colour key
When Func LEDs is on, FUNC1 (above the FUNC1 button) shows the input level and FUNC2 the output level. Each LED uses a smooth colour progression so you can read level at a glance without watching the OLED:
| Colour | Approx. level | Meaning |
|---|---|---|
| Off / dim green | < −10 dBFS | Clean, plenty of headroom |
| Bright green | −10..−5 dBFS | Healthy signal level |
| Yellow | −5..−2 dBFS | Approaching ceiling — caution |
| Orange | −2..−1 dBFS | At the soft-clip threshold |
| Red | −1..0 dBFS | Right at the ceiling |
| Magenta | > 0 dBFS | Soft-clipper actively catching peaks |
Magenta means the cubic soft-clipper is gently saturating peaks that would otherwise digital-clip — audio is still safe, but you’re hearing soft-saturation character. Held for ~30 frames so a one-shot transient hit stays visible after the signal has already dropped back to safe levels.
When Clip LEDs is off, the magenta latch is suppressed but the red zone (peaks at the ceiling) still renders.
The two meters are fully independent — Audio Input never bleeds into the Output meter regardless of Master Volume, FX returns, or input-track gain. So you can use the Input meter to set Scarlett / external audio levels without the synth signal interfering.
