Yamaha CS-30

Yamaha

It gives full analog control—but only one note at a time, no memory, and no way to save what you build.

The Yamaha CS-30 is a monophonic analog subtractive synthesizer introduced in 1977. It has two VCOs, two resonant VCFs, two VCAs, three envelopes, a ring modulator, external audio triggering and an 8-step sequencer. It has a 44-key keyboard. It lacks onboard effects, memory and MIDI. It is used by 808 State.

    What it is

    It is a large, knob-heavy, monophonic synth with a short 44-key keyboard and no memory.

  2. 1:44
    How it works

    Two VCOs, two resonant VCFs, two VCAs and three envelopes give deep, immediate analog shaping.

  3. 3:19
    What it does well

    The 8-step sequencer, ring modulator and external audio triggering make it a sketchpad for rhythm and texture.

  4. 5:05
    What it lacks

    No onboard effects, no memory, no MIDI—only raw analog circuitry and manual control.

Worth your time?

Yes. Use the whole thing.

The written brief1 min read

What it is and what it was built for

A monophonic analog subtractive synthesizer built in 1977 for live sound design and studio sketching.

How it works, in terms a player would use

It is played monophonically on a 44-key keyboard. Two VCOs feed two resonant VCFs and two VCAs. Each filter and amplifier has its own envelope. Oscillators have separate outputs. A ring modulator sits in the signal path. External audio can trigger the envelope. An 8-step sequencer runs patterns or arpeggios.

What it does better than anything else

It gives immediate, tactile control over every stage of analog synthesis: oscillation, filtering, amplification, modulation and sequencing—all with dedicated knobs and patch points.

What it does badly

It cannot store sounds. It has no effects. It cannot sync to external clocks or send/receive MIDI. Its 44-key range limits melodic reach.

What people made with it

808 State used it for early electronic compositions.

Who should use it, and who should not

Players who value direct knob-per-function control and enjoy building sounds from scratch. Not for producers relying on presets, DAW integration or polyphonic lines.

Is it worth your time

Yes—if you want hands-on analog shaping without memory, effects or MIDI. No—if you need polyphony, recallable patches, or integration with modern workflows.

Yamaha CS-15YamahaThe Yamaha CS-15 is a monophonic analog synthesizer produced by Yamaha from 1979 to 1982. It features two voltage-controlled oscillators, two 12 dB/Oct multi-mode voltage-controlled filters (low-pass, high-pass or band-pass), two ADSR envelopes and a low-frequency oscillator. It also features white noise and an external-in for processing other sounds. The CS-15 offers great flexibility with various routing possibilities to the filters and envelopes. You can, for example, route VCO 1 to both VCFs and the VCFs to any of the envelopes positive or negative voltage. It's actually a duophonic / bitimbral synthesizer but you have to connect it to two separate CV/Gate controls (Hz/V like Korg synthesizers not V/Oct) to play the extra voice. In the CS series, the CS-5, CS-10, CS-30 and CS-30L were similar in sound, structure and design. The CS-5 and CS-10 had a single oscillator and one multimode filter, whereas the CS-15, CS-30 and CS-30L each had two oscillators that could be routed in various ways through two multimode filters.

Roland SH-5RolandThe Roland SH-5 is a monophonic analog synthesizer introduced in 1976. It has two VCOs, two LFOs, two multi-mode filters, two VCAs, a 5-source mixer, stereo panning, portamento and ring modulation. It is no longer manufactured. No technical specifications are available.

Roland VP-330RolandThe Roland VP-330 is a 1979 paraphonic vocoder and string machine. It combines ten-band vocoding, electronic strings, and four synthetic choir sounds using seven shared bandpass filters. Its BBD ensemble effect thickens all three sections. Touring musicians adopted it as a lighter, more robust alternative to the Mellotron — despite its choir and strings being less realistic. It offers no patch memory, no MIDI, and no polyphonic independence.

Yamaha CS-5YamahaThe Yamaha CS-5 is a 1978 monophonic analog synth with one oscillator, a multi-mode 12 dB/Oct filter, and an LFO with sample-and-hold. It has no patch storage, no MIDI, no velocity sensitivity. It is built for immediacy — not recall.
