Ambience is a generative ambient synthesizer for Apple Silicon Macs. Hold one note and it builds a living chord bed of layered pads, granular texture, shimmer and arpeggios that never loops and never repeats. Five blendable layers make up the engine: Foundation (sub drone), Anchor (main pad, four timbres), Aurora (shimmer and air), Texture (granular), and an Arpeggiator with three voices. Movement drum engine adds gentle rhythmic motion with four named patterns plus a 16-step custom sequencer. All 12 keys, five chord types, and a custom chord-degree builder. The harmonic engine auto-evolves on a cycle you set. Listen Mode drives the harmonic engine from your playing in real time: move to a new chord and Ambience follows your voicing. Follow Transport locks every layer to your DAW on a single gate. Press play and the drone blooms; stop and it fades cleanly. Full studio effects chain: chorus, tempo-synced delay, reverb, pitch-rising shimmer, four-band EQ, saturation, HPF/LPF and stereo width.AU, VST3, CLAP and Standalone.
