## Buttons and knobs

| Control | Does |
|---|---|
| **SEED** | A new random seed. The old one goes into the history (last 16). |
| **RUN** toggle | Start / stop. Stop sends note-offs, All Sound Off (CC 120) on the learned kit channels, and CC 120 and 123 on the synth channel. |
| **ENERGY** | Density. See [concept](concept.md#energy). |
| **DRIFT** | How loose and changeable. See [concept](concept.md#drift). |
| **Track button**, tap | Track on / off. |
| **Track button**, hold (> 250 ms) | Flips the track only while held: a quick drop-out or punch-in. |
| **Encoder**, turn | Choose the page. |
| **Encoder**, push | Edit the page (the value line inverts). Turn to change, push again to leave. |

Option (bench setting in the simulator): track changes wait for the next bar line.

## Screen

The Nokia 5110 has 84 × 48 pixels:

- **Top line**: the page name.
- **Second line**: its value, inverted while you edit it.
- **Below**: a 4 × 3 map that mirrors the buttons. The top-right cell is RUN: filled while playing.
  - filled = on
  - outline = off
  - flash = hit
  - dot = a kit track not learned yet
  - blinking = a change waiting for the bar line

## Pages

| Page | Edit with the encoder | Push |
|---|---|---|
| **SEED** | scroll back through the last 16 seeds (`-1`, `-2` …; `*` = re-rolled) | load the shown seed |
| **GEN** | EUCLID, SKELETON, SUBDIV, AUTOMATA, AMENIZER | done |
| **ROOT** | AUTO, C … B. AUTO shows the seed's pick | done |
| **SCALE** | AUTO, then the 21 scales (see [Concept](concept.md#scales)). AUTO shows the seed's pick | done |
| **BPM** | tempo | done |
| **SLOT** | 8 slots for seed + salts + generator (not root or scale) | push = load, long push = save |
| **ROLL** | KIT or LINE | push re-rolls just that half (a new drum part over the same tune, or the other way round), then goes back to page select |
| **LEARN** | — | push, press a kit track button, hit the pad on the sampler or drum machine. Push again to cancel. |
