Five voices, clear roles.
Melody, two accompaniment voices, bass, and drums. Give each a sound and a part to play, then hear how they work together.

A little structure. A lot of possibility.
Melody, two accompaniment voices, bass, and drums. Give each a sound and a part to play, then hear how they work together.
Edit notes, chords, rests, and rhythms. Shape your own progressions in patterns up to 16 bars, then reuse and vary them across your song.
Export MIDI, WAV audio, or an editable Eidolophone project. Play through the included recorded SoundFont, or load an SF2 or SF3 of your own.
The workshop
Start with a blank pattern, study a template, or open the included Showcase Project. Every starting point leads back to the same instrument.
The listening room
Music-responsive visualizers turn a listening session into moving landscapes, light, and geometry.
