AMB-1 at a glance

For AMB-1 1.3 · checked against its source

A generative ambient machine after Eno's Music for Airports: it plays itself from power-on. You don't perform it, you tend it: turn PRESETS for another piece, and press keys to change the scale.

The scale: lit keys are in it; press to add or remove that note (every octave)

Good to know

  • Eight pieces, each its own key, tempo and sound: Garden, Departures, Voices, Afternoon, Night Bus, Shoreline, Glass, Tides.
  • Hold any button (but PLAY) for a second: a card explains what it does.
  • The root note always stays, and the scale keeps at least three notes.
  • Editing the scale with the keys turns the mode into Custom; ALGORITHM loads a full mode again.
  • It autosaves a few seconds after a change, but only while resting (PLAY off). A dot on screen means unsaved changes.
  • While frozen (REC), EDIT's chord change waits until you thaw.
  • Notes on MIDI channel 1 add or remove scale notes like the keys; MIDI clock sets the tempo (EXT).
  • Hold OCT- and OCT+ for 5 seconds for update mode; let go early to cancel.

A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
