The E & MM Spectrum Synth
|
| The Spectrum was a DIY project from the early 1980's. A professional
front panel and ready made PCB's were available from Maplin Electronics,
whilst the CEM IC's were available from Digisound. Being a DIY project,
some examples are of excellent quality and others never made it off the
bench! |
| The unit was a well specified 2 VCO switch routed synth with a few
nice touches. |
| The Spectrum is based around two CEM 3340 VCO's (Curtis Electro
Music), CEM 3320 filter, CEM 3330 VCA and CEM 3310 envelope generators. |
