Aether Jam

Aether is the simplest way to jam progressive and melodic house from your phone. Build a track as a stack of layers — Bass, Chords, Drums, and a live Lead — each started from a curated loop and tuned with friendly controls. No timeline, no clutter: just pick a sound and play. One synth, everywhere. A single wavetable engine powers Bass, Chords, and Lead. Morph the oscillator from sine to saw to square, sweep the filter, shape the envelope, and save your sound to a global library you can reuse on any layer. Play, don't program. The Lead is performed live on a scale-locked pad grid — every pad is in key, so there are no wrong notes. Hold several pads for chords, slide for glissando, and ride the one-finger filter-morph ribbon. The shimmer river. A shared shimmer-reverb send that any track can attach to or detach from with a tap — add lush, blooming octaves to exactly the tracks you want. Make it yours. • Swap loops, kits and chord progressions in one tap • Per-track volume faders and mute • Adjustable tempo, live • Transpose the bass, change the lead octave • Record your jam to a file and grab it from the Files app Everything stays on your device. No account, no sign-up, no data collected. Plug in headphones and start jamming.
