Moog Source

Moog · 1981

Moog’s first preset synth trades playability for memory — and never recovers the balance.

The Moog Source is a monophonic analog synthesizer made by Moog Music from 1981 to 1985. It was Moog’s first with patch memory and the only Moog with a membrane keyboard and multihued panel graphics. It stores 16 presets onboard and expands memory via audio cassette. Its 24 dB/octave VCF, two analog ADSRs, LFO and sample-and-hold deliver classic Moog tone — but its interface sacrifices playability for recall.

    Analog voice, digital memory

    It is a monophonic analog synth run by a Z80 microprocessor — Moog’s first digital brain inside an analog body.

    Patch memory, then and now

    It holds 16 presets onboard — and expands that via audio cassette — making it Moog’s first truly recallable synth.

    The only Moog that looked like this

    Its flat-panel membrane keyboard and multihued graphics broke every Moog design rule — and never returned.

    What the circuit gives, and withholds

    It delivers Moog’s 24 dB/octave filter, two analog ADSRs and LFO/sample-and-hold — but with no real-time tweakability.

The written brief1 min read

What it is and what it was built for

The Moog Source is a monophonic analog synthesizer made by Moog Music from 1981 to 1985. It was built for players who needed reliable preset storage and portability in an era when most Moogs had none.

How it works, in terms a player would use

The Moog Source is controlled by a Z80 microprocessor. It uses a flat-panel membrane keyboard — not mechanical keys — and multihued panel graphics. Players store patches in 16 onboard presets or save them to audio cassette. Two VCOs offer three waveforms and three octaves. The 24 dB/octave VCF has cutoff, resonance, keyboard tracking and envelope amount. Two analog ADSR envelopes drive the VCF and VCA. LFO and sample-and-hold provide modulation. A rudimentary sequencer is built in.

What it does better than anything else

It does patch recall better than any earlier Moog. It is the only Moog with onboard memory and cassette expansion. Its multihued panel graphics and flat-panel interface were unique in Moog’s line — a deliberate break from tradition.

What it does badly

It falls short on tactile response: the membrane keyboard gives no velocity or aftertouch. Its preset system is rigid — no parameter locking, no partial updates. The sequencer is rudimentary. Cassette saving is slow and unreliable. There is no way to edit a patch while playing it.

What people made with it

The material does not state what people made with it.

Who should use it, and who should not

A player who values Moog’s analog voice and wants hands-on preset management should use it. Anyone needing expressive keyboard control, polyphony, real-time modulation routing or modern workflow integration should not.

Is it worth your time

It is worth your time if you want a monophonic analog synth with patch memory and cassette storage from 1981 — and can accept its membrane keyboard, fixed architecture and lack of real-time control over many parameters.

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.

One oscillator. One filter. One envelope. Zero compromises — and zero flexibility beyond that.
