Kosmonaut is Multitap Delay with a twist. In addition to adding echoes to your audio, it packs a bunch of extra tools to put your music in space:

- Tape looper with with variable sound-on-sound decay level
- 4-Tap Delay (placed in series for complex feedback loops)
- LP/HP filters with LFO
- Autopanner
- Ambiance Generator
- Haas Effect Processor (aka 'wavefront precedence effect')

All features are demonstrated extensively in a ton of factory presets, and you can easily add your own user presets, which will automatically carry over across different host apps.

All variables are exposed as AU Parameters in hosts which support automation.

It also has a smart Random-feature, which may come up with usable results :-)

Check out ruismaker.com for the user manual and audio demos.

Version 1.0.3 release notes
