What Evander's Music Box does

  • Twenty acoustic voices cover harps, lutes, koto, psaltery, choir, hurdy gurdy, bagpipe, cello, winds and three drum kits.
  • Bardic Crafting gives four tracks with a 64 step sequencer, microtiming, TONE locks, swing and live looping on REC.
  • Encounter turns the sixteen white keys into scenes from tavern to boss fight, changing on the next bar with a crossfade.
  • Once a scene plays, the eleven black keys darken it, raise the key, halve the time, strip it back or fire a stinger.
  • Hold GLO and a key to set a root and scale so keys, sequencer, scenes and freestyle stay in one scale.
  • Press HOME plus FX plus GLO to unlock saw, supersaw, pad, acid bass, FM and electro kit sounds.
  • Autosave keeps steps, loops, instruments and settings every 30 seconds, so the Box wakes exactly where you left it.
  • Plug into a computer with a data cable for class compliant USB audio and MIDI, recording straight into a DAW.
