This module is a personal design of the Rob Hordijk Benjolin in a Buchla format as described on the Muffwiggler Bejolin 4U forum. I was sent a copy for my help in making modifications necessary for a Buchla module.
It is a two PCB module and the boards are of high quality.
The finished module is very clean.
For operational information you can visit my 5U Benjolin page. This Buchla version features attenuverters, a push-button randomizer for the 8 and 16 step sequences, and external inputs to the rungler.
