The CS-5 is a single-oscillator monophonic analog synthesizer made from 1979-1983 with classic filter, envelope and modulation controls. It features 37 full-sized keys, a multi-mode 12 dB/Oct resonant filter, an LFO with sample and hold, and an external audio input you can route through the VCF or VCA sections.
The CS-5 is a very flexible and modulate-able analog synth that is quite capable of warm analogue bass and bubbly synth effects! It has no patch storage, MIDI and velocity, but who needs that crap. Knob twiddling at its best..
Many moons ago, I was in 8th in 1988 and the music class I was in, had a back room full of odds and ends and if we finished our classwork early, we were lucky enough to muck about with a Yamaha CS 5 and a blue faced ARP 2600, alas, with no keyboard.
All in what was probably five minutes a day, which to me felt like hours, I turned each knob on the CS5 to scientifically work out for myself what effect they had on sound. Even though I had no concept of what an oscillator or a filter was then, I had fun playing with it and good memories. Hopefully one day, I’ll get a CS5.
The video is a good demo of the CS5 and features some good reverb and experimental sounds.
