Elektor polyphonic synthesiser

Jump to navigation Jump to search

The Elektor polyphonic synthesizer was a design published in Elektor magazine from October 1981 to July/August 1982, based on Curtis ICs.


The synthesiser design is an expansion of the monophonic Elektor new synthesiser, with a Z80-A CPU to scan the keyboard and to store preset sounds. It can have up to ten voices each consisting of one or two VCO modules, one combined VCF/VCA module and one dual ADSR module. The design of a compatible digital oscillator was published in June 1985.[1]
