The Yamaha CS-30L is a full-fledged synthesizer developed based on Yamaha's superior technology and experience with Electone Organs. It features two systems of VCO, VCF, and VCA, along with three EGs (Envelope Generators). The instrument allows for the creation of new sounds through voltage control of oscillation, filtering, and amplification.
The synthesizer electrically synthesizes and controls interval, tone, and volume.
You should never apply more than 5V to the KEY VOLT IN terminal.
The synthesizer can be connected to one or two amplifiers.
