"Elric is/was a dual-VCO monophonic keyboard synthesiser designed in 1984. It used the Curtis Electromusic analog synthesiser ICs under control of a microprocessor.Elric has one, fixed patch: a four channel audio mixer feeds a VCF whose output feeds a VCA with stereo outputs. There are two VCOs and a ring modulator. The four inputs to the audio mixer are sourced from the VCOs, the noise generator and the ring modulator. The ring modulator inputs are hardwired to the VCO outputs. One VCO can be synched to the other."
