Orbital MIDI Generator by PlayMode Audio
Turn planetary motion into music with Spira, a generative MIDI instrument that transforms orbital movement into evolving melodies, hypnotic arpeggios, and complex polyrhythms. With up to 48 planets triggering notes as they cross interactive beams, Spira opens up endless possibilities for musical experimentation.
Explore 34 scales and chord sets, experiment with six built-in chord progressions, or generate an entirely new musical universe with a single click. Its built-in sound engine, tempo-synced effects, and MIDI output let you create directly within Spira or control your favorite synths and samplers.
Featuring 20 factory presets, DAW synchronization, and customizable rhythmic patterns, Spira is an inspiring tool for ambient, cinematic, electronic, and experimental music production.
Note: Spira is available for Windows 10 or newer (64-bit).
