Roland SH-3A

Roland

Roland’s first non-preset synth doesn’t just break from tradition — it splits synthesis in two directions at once.

The Roland SH-3A is a monophonic analog synthesizer introduced in 1975. It supports both subtractive and additive synthesis. It includes two LFOs and a unique sample-and-hold section. It was Roland’s first non-preset based synth. It uses a transistor ladder-filter to produce Moog-like sounds.

    No presets. No compromises.

    It is Roland’s first fully manual, non-preset monosynth.

  2. 2:22
    Two synthesis modes in one signal path

    It is the only Roland monosynth that supports both subtractive and additive synthesis.

  3. 3:33
    LFOs and sample-and-hold, built-in

    Two LFOs and a dedicated sample-and-hold section were rare in self-contained synths of the mid-70s.

  4. 4:50
    Moog-like tone, by design

    Its transistor ladder-filter delivers Moog-like warmth — unlike the earlier SH-3’s diode filter.

Worth your time?

Yes. Use the whole thing.

The written brief1 min read

What it is and what it was built for

The Roland SH-3A is a monophonic analog synthesizer introduced in 1975. It was built for players who wanted full manual control over tone generation without preset constraints.

How it works, in terms a player would use

It runs two oscillators with mixable waveforms at different footages. It routes signal through a transistor ladder-filter. It uses two LFOs and a sample-and-hold section. It has no presets — every sound is built from scratch.

What it does better than anything else

It is Roland’s first non-preset synth and the only Roland monosynth that natively supports both subtractive and additive synthesis in one signal path.

What it does badly

It cannot play chords. It offers no memory for patches. Its additive mode is limited to mixing fixed waveforms — no harmonic editing, no real-time spectral shaping.

What people made with it

The sources do not state what people made with it.

Who should use it, and who should not

A player who values tactile, immediate synthesis with dual-mode flexibility should use it. A producer needing fast recall, polyphony, or modern modulation routing should not.

Is it worth your time

Yes, if you want hands-on control over both subtractive and additive synthesis in a single monophonic analog instrument. No, if you need polyphony, presets, or digital recall.

Alesis Andromeda A6AlesisThe Alesis Andromeda A6 is a 16-voice, 16-channel multitimbral analog synthesizer released in 2000. It combines a pure analog audio path with digital control. Its VCOs include pitch correction—a feature missing on older synths. Alesis developed a custom ASIC for it. Axel Hartmann designed it. It is high-end, innovative gear from Alesis, a company known for budget equipment. Alesis developed studio equipment during the 1990s.

ARP AvatarARP · 1977The ARP Avatar was a 1977 guitar-controlled synthesizer module. It copied the ARP Odyssey’s synthesis architecture but removed the keyboard and added a 6-way fuzzbox. It required a hexaphonic pickup and pitch-to-voltage conversion. It failed commercially. Sales totalled $1 million over two years against $4 million spent on R&D and production. It contributed to ARP Instruments’ bankruptcy in 1981.

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.

Doepfer A-100DoepferThe Doepfer A-100 is an analog modular synthesizer system introduced in 1995. It uses 3U-height, 2HP-width modules patched with 3.5 mm leads. It established the Eurorack standard adopted by many manufacturers. It enables emulation of the Trautonium and Theremin using specific modules.
