Rollz-5 Drum Machine

Here's my implementation of the Ciat-Lonbarde Rollz-5 drum machine. The geometric jack arrangements are pulse generators. The banks of knobs are filters: the left produce drum like sounds, the ones on the right tones. The upper four filters heterodyne and make weird shortwave radio-like sounds. You connect the pulse generators to make patterns then patch thru a filter to output. [click on pics to enlarge]
