Yamaha CS30/CS30L is an analog [ame="http://en.wikipedia.org/wiki/Keyboard_instrument"]
keyboard [ame="http://en.wikipedia.org/wiki/Synthesizer"]
synthesizer that was released in 1977. It is the top of the range in Yamaha's original line-up of monophonic synthesizers, others in the range being the CS5, CS10 and CS15. It features two voltage controlled oscillators (VCOs), two voltage controlled filters (VCFs - both featuring low-pass, band-pass and high-pass options), two voltage controlled amplifiers (VCAs) and three envelope generators. It also sports a ring modulator and a voltage controlled low-frequency oscillator (LFO).
It is fairly unusual for a hard-wired synthesizer in that it features a variety of switches which allow the user to re-route the signal flow from the usual VCO-VCF-VCA convention. For example, VCO 1 can output a square wave through VCF 1 whilst also outputting a high-pass filtered sawtooth wave through VCO 2. Another example is that the envelope generators can be assigned to any of the VCO, VCF and VCA modules and can also be inverted. Because the LFO is voltage controlled, the oscillating speed can be governed by an envelope generator and different waveforms can be applied to the other modules all at the same time. The CS30/CS30L also features an external signal input for filtering other musical instruments and audio sources, which can also be used as a modulation source.
As Dave mentioned, it is by no means a CS-80, but you can make it sound pretty much exactly like a monophonic CS-80 in as much as it uses exactly the same VCO's, waveshapers, VCF's, envelope generators and VCA's as a CS-80. Somehow it manages to stay in tune a lot better though, The CS-30 doesn't get hot inside so the VCO's don't drift much.
2x VCF is eigenlijk een van de veste opties van dit ding. nogmaals, nagenoeg zelfde architecture cs80. maar dan stabieler. (instabieler is nog lekkerder natuurlijk - lees cs80)

dat voor de puristen
