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.
