SEELEWASCHEN 3.0 for Mac could be downloaded from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free software for Mac OS X was originally created by Dr. Karlheinz Essl. We recommend checking the downloaded files with any free antivirus. The program lies within Audio & Video Tools, more precisely Music Production.
From the developer:
SEELEWASCHEN is a free generative sound environment. Using the sound of one single bell stroke as its basic material, the piece unfolds a rich sonic cosmos by a computer program. It can be perceived as a sonic organism which might serve as a source of inspiration and meditation, running forever and ever.
