Sonar ping and echoes
A sonar ping, a long glass note on the key, answered by quieter echoes; the pings crowd together toward every threshold and the echoes return sooner as the counter climbs.

Parameters
| Name | Type | Default | Range | What it does |
|---|---|---|---|---|
| interval | number | 5 | 2.5 to 9 s | seconds between pings at the start of a stretch, at home |
| closing | number | 0.6 | 0 to 1 | how much the pings crowd together as a threshold nears |
| curve | choice | steady | steady, late, early | how the gaps and the echo delay shrink up the ladder: evenly, late or early |
| echo | number | 1 | 0.3 to 2 s | the echo delay at home; it shrinks as the counter climbs |
| echoes | integer | 2 | 1 to 2 | how many echoes follow each ping |
| fade | number | 0.5 | 0 to 1 | how quiet each echo is next to the one before |
| echoPitch | choice | same | same, fifth, octave | the echoes ring on the same note, a fifth above or an octave above |
| pitch | integer | 76 | 60 to 96 | the ping's register (MIDI), moved to the key's root |
| timbre | choice | glass | glass, celesta, harp | what the ping sounds like |
| ring | number | 3.2 | 1.5 to 5 s | how long each ping rings |
| dropout | number | 2.4 | 1 to 5 s | how long before a quiet threshold the pinging stops |
| tail | bool | true | – | after the limit the pings drift apart again through the coda |
| key | choice | C | C, C#, D, Eb, E, F, F#, G, Ab, A, Bb, B | the home key; a channel that leaves it unset gets its own from its seed |
