Product description "Buchla U.S.A. - Music Easel Retro Program Card"
The Buchla Program Card is the "Old School" version of the Music Easel preset memory. - You can solder a preset on the card.
The card is a PCB with solder connections for almost all Music Easel parameters. With the help of a soldering iron and some resistors presets can be created. Since the card and all its connections are completely open, it can also be touched and "played with the hands", which can lead to short-circuit (happy) accidents and crazy glitch sounds.
