Please note: this is an AUv3 plugin that can be used with compatible host Apps. GS-201 Mark II is the evolution of a project that began in 2007 with the release of the old version of GS-201, which evolved into a mark II version in 2019 and has now landed on the iPad platform. The aim is to capture the magic of the famous Space Echo tape delay and make it available to everyone. It's not an easy task, but the experience gained over the past 15 years in audio DSP development has helped us achieve a result that can sometimes fool even ourselves. This iOS version of the GS-201 Mark II contains only the basic controls found on the original Space Echo, with no additional editing parameters. If you want to eliminate tape hiss, if the tape splice glitch is bothering you, if you don't like wow and flutter, or need host tempo sync, you are definitely looking for a different plug-in. If, on the other hand, you want to relive the experience of dealing with an original Space Echo, with all its pros and cons, you are in the right place.

About

Aether Jam

Features
Read full description

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.
