D is for Digisound Project 80
|Originally a project started in 1980 (hence the name of
the modules) by W. Marshall and R.C. Blakey and published in the ETI
magazine. Modules were available as kits, bare PCBs, or later, also
supplied ready built. The manufacture eventually passed to Tim Higham
who continued to offer them for sale until interest seemed to wane in
the mid 90's The talented Mr Higham has since turned his hand to to the
craft of film making...
|The core modules were based around various SSM
and later CEM (Curtis Electromusic Specialties) chips, for sound generation, filtering, envelopes and VCAs
etc. If well built the system was excellent both in sonic terms and value
for money too.
At one point in time I owned a 48 module CEM system containing 4 VCOs, 4 VCDOs, 8 EGs etc. I only wish I hadn't parted with it now, but the lure of undiscovered sounds lurked in the ill fated Polyfusion. The value it realized then was miniscule compared to the prices of today. If anyone is interested, I have the full set of construction notes, users manual and negatives for many of the PCB's.
The Module pages are still only partly built!
