"This project is a personal project. As much as I'd like to release these designs for SDIY there are 2 issues, Firstly there are many errors as this is a first time (and only) build, Secondly I don't have Don Buchlas permission to release these versions (flawed or not).The design is based on the Buchla Music Easel which is pictured in the history section of the Buchla website. The original blueprints can be found here..."
