Moog Subsequent 37 Review: Paraphonic Analog Synth

Good fit if…

• You want the Moog Subsequent 37, a 37-key two-note paraphonic analog synthesizer with official semi-weighted keys and after-pressure, not a Subsequent 25, a Sub 37 Tribute, or a Matriarch.
• You can plan a case and a lift around official manual figures: 6.75 in high, 26.375 in wide and 14.75 in deep, and 22 lb (10 kg). Official power is a universal 100-240 VAC supply at 13 W, with a supplied AC cord to an IEC inlet.
• You will use the official engine and I/O figures: two variable waveshape oscillators, one square-wave sub oscillator, analog noise, external input/filter feedback, a Moog ladder filter with 6/12/18/24 dB-per-octave slopes and MultiDrive, 256 presets, MIDI DIN In/Out plus MIDI over USB, and CV/Gate inputs for filter, pitch, volume and keyboard gate.
• You will register the instrument at moogmusic.com/register (or by phone) so the official U.S. 1-year limited warranty can start, and you will keep the original packing if you ever need a factory return.

Avoid if…

• You wanted a Subsequent 25, a Sub 37 Tribute, a Matriarch, or a polyphonic Moog One. Those are different official models.
• You planned a case around Amazon's 26.77-inch or 26.75-inch width fields as the official unit width. The official manual lists width as 26.375 inches.
• You need more than official two-note paraphonic (duophonic) or monophonic play. Official polyphony is selectable monophonic or duophonic, not a multi-voice polyphonic analog engine.
• You will not register the unit or keep the original packing. Official U.S. coverage is a 1-year limited warranty, return-to-factory with an RMA, and the official manual says the warranty will not be honored if the product is not properly packed.

What you are actually buying

The product on this page is the Moog Subsequent 37, official model Subsequent 37 from Moog Music Inc. The official Subsequent 37 user manual (Subsequent_37_Manual_0.pdf, hosted on Moog's inMusic CDN and read November 10, 2026) describes it as a programmable paraphonic analog synthesizer with a 100-percent analog sound engine, 37 semi-weighted keys with after-pressure, and selectable monophonic or duophonic play. Official manual weight is 22 lb (10 kg). Official manual dimensions are 6.75 in high, 26.375 in wide and 14.75 in deep (17 cm x 68 cm x 37.5 cm). This page covers only the Subsequent 37, not a Subsequent 25, a Sub 37 Tribute, a Subsequent 37 CV, or a bundle whose main item is a case or a stand.

Official manual sound sources are two variable waveshape oscillators, one square-wave sub oscillator, one analog noise generator, and one external input/filter feedback path. Official filter figures are a 20 Hz-20 kHz Moog ladder filter with 6/12/18/24 dB-per-octave slopes and MultiDrive. Official presets number 256 (16 banks of 16). Official connections include 1x TS audio in, 1x TS audio out, 1x TRS headphones, MIDI DIN In and Out, MIDI over USB, and CV/Gate inputs for filter, pitch, volume and keyboard gate. Official input power is 100-240 VAC, 50-60 Hz, 13 W, with a supplied AC cord to a standard IEC inlet. The official unboxing list in the same manual includes a registration card; the Amazon included list on this ASIN names the synthesizer, an owner's manual, a power cord and a registration card.

Buyer Checkpoint has not played this synthesizer; this is a document review with no hands-on test. Moog's current public product page fetched November 10, 2026 did not render a usable specifications table in the saved HTML, so official figures used here come from the official user manual PDF. Buyer Checkpoint's live library is currently stronger in workshop and commercial equipment than in synthesizers. For how these pages are researched and scored, start from how we research and score and the about page.

Listing shorthand and official conflicts

Width is written more than one way. The official user manual lists unit width as 26.375 inches (and 68 cm). The Amazon item-dimensions field on this ASIN lists 14.76 x 26.77 x 6.69 inches, and Amazon product-description copy also prints 26.75 x 14.75 x 6.75 inches. Official height 6.75 in and depth 14.75 in match or nearly match those Amazon figures; the Amazon width values are about 3/8 to 4/10 of an inch wider than the official 26.375 in. This page uses the official 26.375 in width as primary. Confirm the live unit or the official manual drawing before you order a tight case.

Amazon title and feature copy also say “2-note paraphonic.” That agrees with the official manual's selectable monophonic or duophonic polyphony. This page does not treat that as a multi-voice polyphonic analog engine.

Buyer Checkpoint Fit score

Fit 90/100 for a player who wants the official Subsequent 37 paraphonic analog synthesizer, can plan around official manual size and 22 lb weight, and will register the unit for the official 1-year U.S. limited warranty. This score is not raised to fill a publishing slot.

Method: Buyer Checkpoint Fit score for the target buyer profile on the 30/25/20/15/10 framework (Use-case & safety / Documented capability / Integration / Ownership / Supporting evidence). It is an editorial score built from documents, not a laboratory or hands-on test. A hard stop for that profile overrides the total. Other profiles are described under “Avoid if…” without a second numeric score. See the public scoring method.

Total: 29 + 22 + 18 + 13 + 8 = 90. A live listing that is no longer the Subsequent 37, a plan that uses Amazon's 26.77-inch width as the official unit width for a tight case, or a refusal to register the unit and keep the original packing for the official 1-year U.S. warranty is a hard stop for this profile and overrides the 90.

Buying facts that change the decision

Each row pairs a sourced fact with what it changes for the buyer.

Official engine, connections, and what is in the carton

Official manual sound sources are two variable waveshape oscillators, one square-wave sub oscillator, one analog noise generator, and one external input/filter feedback path. Official oscillator calibration range is 22 Hz to 6.8 kHz, with a guaranteed note range at 8-foot of notes 18 to 116. Official filter figures are 20 Hz to 20 kHz, with 6/12/18/24 dB-per-octave slopes and MultiDrive. Official polyphony is selectable monophonic or duophonic. Official presets number 256 (16 banks of 16). Official controllers are pitch bend, mod wheel, after-pressure and velocity. Official transposition is plus or minus two octaves. Official LFO range is 0.01 Hz to 1,000 Hz.

Official audio connections are 1x TS input, 1x TS output and 1x TRS headphones. Official MIDI is DIN In and Out, plus MIDI over USB. Official CV/Gate inputs are filter CV, pitch CV, volume CV and keyboard gate. Official USB here is for MIDI and the editor/librarian, not a multi-channel USB audio interface. Budget a separate audio interface if you need one.

The official manual describes a supplied AC cord into a standard IEC inlet, and a registration card in the carton. The Amazon included list on this ASIN names the Subsequent 37 analog synthesizer, an owner's manual, a power cord and a registration card. Confirm the live carton includes the power cord and the registration information you will need to initiate the warranty.

Official size, power, and the 1-year U.S. limited warranty

Plan the case from official manual figures: 6.75 in high, 26.375 in wide, 14.75 in deep, and 22 lb (10 kg). Do not use Amazon's 26.77 in or 26.75 in width fields as the official unit width. Official input power is 100-240 VAC, 50-60 Hz, 13 W.

Official U.S. warranty is specific. The official user manual's Moog Limited Warranty states that Moog warrants its products to be free of defects in materials or workmanship and conforming to specifications at the time of shipment. The warranty period is one year from the date of purchase. During that period, Moog will repair or replace a covered product, at Moog's option, on a return-to-factory basis, for defects Moog determines are no fault of the user. The official limited warranty applies to USA purchasers only. You must obtain an RMA before returning a product, by calling (828) 251-0090 or emailing techsupport@moogmusic.com. The Subsequent 37 must be returned in its original packing; the official manual says the warranty will not be honored if the product is not properly packed. Send the product to Moog Music Inc., 160 Broadway St., Asheville, NC 28801, with transportation and insurance charges paid.

The same official manual says you should initiate the warranty online at moogmusic.com/register, or by calling (828) 251-0090 if you do not have web access, and that registering the instrument initiates the warranty, helps you receive software updates, and gets you the editor/librarian. If a product is no longer in production and more than five years have passed since it shipped from the Moog factory, the official manual says it will be at Moog's discretion whether to honor the warranty without regard to the customer's date of purchase. Confirm current terms in the official manual and on Moog's current support pages before you pay.

The Amazon seller in this read, and what you should confirm

A November 10, 2026 recheck at delivery ZIP 10001 showed ASIN B074KCBLQ8 in stock from Amazon.com. That is Amazon.com as seller and shipper, not a third-party marketplace seller. A second offer from Alto Music was also visible at a different internal price; this page covers the Amazon.com offer in that read, not a competing seller's terms. Confirm the live seller at checkout.

A dated note is not a promise that the same seller or offer will be there. Confirm the title still reads Subsequent 37, not a Subsequent 25, a Sub 37 Tribute, or a bundle whose main item is a case, and confirm return handling with that seller. Do not treat a remaining-stock countdown on the listing as a reason to rush; this page does not print those counts.

How we score and how we correct pages is documented on the editorial policy and corrections and updates pages. Affiliate links are explained in the affiliate disclosure.

How to confirm the live listing without trusting a dated note

Open ASIN B074KCBLQ8 and read the title and the model. You want a Moog Subsequent 37. If the title names a Subsequent 25, a Sub 37 Tribute, a Matriarch, or a bundle whose main item is a case or a stand, stop: this page does not apply.

Then read the seller and the offer type. A November 10, 2026 recheck at delivery ZIP 10001 showed the instrument in stock from Amazon.com. A second offer from Alto Music was also visible. Confirm the live seller, then plan to register the unit at moogmusic.com/register so the official 1-year U.S. limited warranty can start. A dated note is not a promise that the same seller or offer will be there; adding the instrument to your cart does not reserve it and does not lock a price.

Buyer Checkpoint did not play this synthesizer and did not measure keybed feel, after-pressure, output level or CV response. Official figures used here come from the official user manual PDF, because Moog's public product page did not render a usable specifications table in the saved HTML. Official unit width is 26.375 in; Amazon lists 26.77 in and 26.75 in. Official U.S. coverage is a 1-year limited warranty that requires registration and original packing for a factory return. This Amazon read is not an Ops delivery-ZIP 10001 recheck.
