My Initial Thoughts

Moog Sub 37 is a paraphonic analog synthesizer with 37 velocity-sensitive keys.

It contains two oscillators and a sub oscillator, a white noise generator, a low-pass filter, two high-speed LFOs, and two DAHDSR looping envelopes.

DAHDSR stands for Delay, Attack, Hold, Decay, Sustain, and Release.

You only need one look at this synthesizer to get a feeling of how awesome it is.

This is quite a heavy synthesizer with a solid feel, and you’ll immediately notice the craftsmanship and attention to details that were put into this model.

You can’t judge a synth only by its looks, of course, so let’s take a closer look at what Moog Sub 37 has to offer.

Feel, Specifications, Dimensions, and Integrations

The Sub 37 is actually a hybrid, somewhere in between an analog and a digital synth.

The signal path is analog, but it’s controlled y digitally generated modulators and contour generators.

It’s also called “paraphonic” and in this case, it means that the two oscillators can be played independently in real time while they are both sharing the same filter. 

The easiest way to describe the sound of the Sub 37 is, well, the “Moog sound”.

It produces a beautiful, rich, analog sound.

I’d describe it as a sound that’s a bit on the darker side, but that doesn’t mean it’s dirty or muffled (if you don’t want it to be).

Advanced Features and Performance

On the left side of the synth, there is a panel that house all of the inputs and outputs.

It includes audio in and out, CV inputs, Midi IN/Out, USB, and, of course, the power supply input.

The USB port transmits only MIDI and not audio, but it can also be used to control the synth from a PC via the downloadable Sub 37 software editor.

Above the keyboard, there is a large panel housing all of the controls, and there are a lot of them indeed.

They are logically organized and feel very smooth and solid.

In total, there are 40 knobs and 74 switches.

Since there are so many of them, all of the controls you’ll need to use frequently are laid out on the front panel.

The controls are accompanied by an LCD display which is quite small, but still big enough to serve its purpose.

Pros & Cons of Sub 37


Incredible high-quality sounds

The dual oscillators provide great flexibility and freedom of expression

An impressive arpeggiator with step sequencing functions

Allows for direct control from a PC/Mac


Might be too big if you have limited space

Difficult to clean, additional cleaning supplies are needed to properly wipe

It has only 37 keys which might feel a bit restrictive for advanced users

No CV output

My Final Thoughts

As always, I tried to give you a streamlined overview of the pros and cons of the synthesizer in question.

The thing is, with Moog synthesizers, it’s hard to come up with reasons why you shouldn’t get one.

The paraphonic architecture of Sub 37 produces a unique sound accompanied by extensive modulation possibilities.

The control panel allows you to control the myriad features of this synth as easily as possible.

If you are seriously considering picking up a modern Moog, definitely consider the Sub 37.
