All-analog Marriage of Harmony and Rhythm

The newest addition to the Moog Mother Ecosystem, the Moog Subharmonicon semi-modular analog synthesizer and sequencer brings all the Moog analog flavor with a rhythm entirely its own. First released in a limited run of 120 units in 2018, the Subharmonicon became an instant cult classic for its unique take on subharmonic synthesis and polyrhythmic sequencing. With two VCOs, each with two suboscillators and a four-pole resonant filter, the Subharmonicon produces creamy all-analog tones with basement-dwelling lows and scorching high-end. Its truly innovative sequencing capabilities use a combination of two four-step sequencers (one per VCO section) and a polyrhythmic generator to create wild, erratic polyrhythms and evolving harmonic chordscapes. Use it as a standalone semi-modular synthesizer or insert it into your Eurorack system for infinite sonic exploration. Synthesists at Sweetwater have been waiting to get their hands on the Moog Subharmonicon, and it was well worth the wait. For a sound design tool like no other, check out the Moog Subharmonicon today!

Legendary ultra-fat Moog synth tones

The Subharmonicon owes its ultra-fat sound to its two analog VCOs — each with two separate suboscillators — which churn out the warmth and grit for which Moog synths are known. The suboscillators divide the fundamental frequency of the VCOs down to four octaves below in 15 subdivisions, and their sawtooth waveshape packs a punchy wallop distinct from sine or square wave suboscillators. By independently tuning the VCOs and subs, you can generate massive chords that track with the VCO frequency, turning this monosynth into a pseudo-polyphonic pad machine. To shape the signal, the Subharmonicon includes a VCA and self-oscillating 4-pole lowpass resonant filter, with variable attack and decay controls. Even without the sequencer and patchbay, the Subharmonicon is a formidable analog synth that produces hearty sub-bass and screaming leads.

Brain-twisting polyrhythmic sequencing

What really sets the Subharmonicon apart from other modular synths is its idiosyncratic sequencer section. The Subharmonicon has two 4-step sequencers, which can impact the VCO or suboscillators’ rhythms and frequencies. While four steps might not seem like a lot, when paired with the Subharmonicon’s polyrhythm section, you can quickly dial up loping, swinging rhythms, with dotted notes, triplets, and out-of-time pulses that twist the sequence in unexpected ways. You can adjust the tempo manually or quantize the rhythm to an external clock to sync to your Moog Mother Ecosystem modules and third-party Eurorack units. From percussive sounds to complex, moving chords, the Subharmonicon is capable of creating textures unlike any other semi-modular synth in its class.

Make it the heart of your Eurorack System

Like the Moog Mother 32 and Moog DFAM, the Subharmonicon is equipped with a 32-point patchbay for expansive routing possibilities. Output the sequencer as control voltage to other Eurorack VCO units and modulators, and control parameters like filter cutoff, pulse width modulation, polyrhythmic controls, and more via external devices, such as LFOs. Or patch within the Subharmonicon itself to explode its creative potential. This 60HP semi-modular synth makes a great desktop unit, and it’s a perfect synth to serve as the centerpiece of your Eurorack system.

Moog Subharmonicon Semi-Modular Polyrhythmic Analog Synthesizer Features:

  • Wide-release version of a limited-edition cult-classic synth

Moog Subharmonicon

Moog created a very interesting synth. The sequencer allows poly rhythms to be programmed. It's a must have if using a DFAM or Mother 32 synth. All Moog products are high quality, very well made, it's oscillators sound amazing! I highly recommend it to anyone producing Electronica, Techno, Deep House, Drum N' Bass even Hip Hop. Sky's the limit. You'll love it's tone.

3 words: Take Your Time

This thing sounds absolutely amazing, but you probably already know that. It has this Moog thing that only a Moog has...

However, this is by far the most frustrating instrument I ever owned. All these YT videos made me feel like it was impossible for it to sound bad but I couldn't be any further from the truth. Happy accidents don't come that often and are a lot more deliberate than you might think.

Took some time to really understand the logic and mechanics of the sequencers and rhythm generators but when it finally clicked... WOW

A Musical Device for Sonic Exploration.

The Moog Subharmonicon is a complex device made to accomplish amazing things. If you're new to synth approach with caution, this is not a beginner device. This is not a synth with presets, nor a synth that gives over successful synthesis repeatedly to anyone unwilling to put in the effort and work required. Your desire to explore sound in a fascinating way will be rewarded, but nothing will be handed to you. One exception to that is the Subharmonicon does come with templates to suggest settings and results, and that is pretty cool; perhaps they are a "preset" of sorts. They're also a lesson in how to get good sound from the machine. The Subharmonicon is one synth where you really should read the manual and do your YouTube research. When it all comes together, this thing is an ambient sound maker's dream come true. If you like something you've made, I recommend recording it via your DAW, so you have it. Duplicating results on the Subharmonicon is just shy of impossible, I don't think repeated results were ever the point. For me, that constantly flowing river of potential, never the same thing twice, is its greatest asset and gives it the most artistic appeal. This thing is exactly for new creation every time. Once you get it down, you will amaze yourself with new sonic results and happy accidents. The adventure of it all was unexpected and welcome, and I love it. It's a synth for a lifetime and utterly unique. Buy it, and dive in, go deep. It's endless.

Math and Music Come Together

If your a synth enthusiast looking for something different and inspiring, then this is for you.
If you are just a person who enjoys math, then this is for you.
Why?
Once you get the hang of how to use this and get great results (and I mean great!) you will come to realize its all about math. Such a beautiful thing, where music and math converge, and this synth takes it to a whole new level.
25 years from now, people will be scrambling to find one of these synths, as it is certain to become a classic.
If you already own one of these, you might want to buy another and leave it untouched in the box for 20 years. (Hint, Hint)

Moog Subharmonicon

I am glad I made the purchase. I am learning and having fun along the way. Gets even better when I pair it with my Moog Mavis. No regrets.

Want real Moog sound? Take it from the die-hard analog synth masters here at Sweetwater: buy a Moog. It doesn't matter which one; their synths start at top quality and only go up from there. Sweetwater's relationship with Moog goes way back, and some of us fondly remember the last time Bob himself came to visit. Over the years, we've had the honor of watching Moog grow and evolve, and with synthesis experts like Daniel Fisher on staff, we're still one of the first companies to catch wind of new Moog products - they never fail to impress! Whether it's a classic reissue, a breakthrough new keyboard, or even a cool effects pedal, you can be sure anything you get from Moog will make you happy, and we'd love to tell you all about it.
