Classic mono synth perfectly capable of many sounds, the CS-5 is a single-oscillator monophonic analog synthesizer 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.
Tested in fantastic working condition, showing average wear and tear. All switches and knobs work as expected.
