Elektor new synthesiser

The Elektor new synthesiser was a monophonic analogue synthesiser design published in the UK edition of Elektor magazine from October 1981 to March 1982, mostly based on the new, at the time, Curtis ICs and intended to be portable for live performance.

Description

It uses the same designs for the keyboard and control and output module as the Elektor Formant. Presets can be stored via 4066 CMOS switches. Two VCOs are CEM3340s, the VCF a CEM3320, the two ADSRs are CEM3310s, the two VCAs are based on the same circuit as used in the Formant, utilising a CA3080 OTA, the LFO (triangle wave only) is a LM324 op-amp integrator and white noise is produced by the base/emitter junction of an NPN transistor.
