The New Row Power Supply :

Coming out July 26th!

Row Power is a clean, regulated, and protected power solution for eurorack systems. Row Power 35 provides 35W of power, suited for any typical eurorack row (84HP to 168HP):

Simply plug a universal power supply (laptop style) into either of the barrel plugs on the 4HP panel. Connect your modules via flying-bus cables or the Bus Stick.

Daisy-chain multiple Row Powers to use a single power brick for multiple rows (typically 3-5 rows per power brick). Each row will be independently regulated and protected for ultra-low cross-talk between rows. Rows can also be hot-swapped (plugged/unplugged without powering the whole system down).
Enclosures for small systems :

Pods are a perfect way to get started in Eurorack or add a couple more modules to your monster system. Made from 100% anodized aluminum, Pods are light, tough and perfect for on-the-go set ups.

Mix and match your Pods with desktop synths, effect pedals, drum machines or any musical gear for a flexible modular system. Pods can even daisy- chain with the 4ms Row Power system making them a convenient outboard mini-skiff.

Need to add another module? Just add a Pod!

Need to pack light for a live set? Just grab the Pods you need and go!

From 20HP to 60HP, whether you choose the shallow original Pods or the deep X-series, there's a Pod for your modules!
SphereEdit for the SWN :

SphereEdit for ... Mac ... Windows ... Linux

SphereEdit is a free, open source software compatible with Mac, Windows, and Linux that allows you to create, edit, import and export waveforms and load them into the Spherical Wavetable Navigator (SWN) using an audio cable.

The SWN is ready for you to create and save your own wavetables. With SphereEdit you can do just that! From drawing custom wave shapes, to adding effects, to importing and splicing audio files, SphereEdit is a fun and easy way to create new wavetables for your SWN.

For more information on how to use SphereEdit, download it now and check out the SphereEdit User Manual .

Spherical Wavetable Navigator


The Spherical Wavetable Navigator (SWN) is a six-channel synthesizer that makes it easy to create slowly morphing drones, polyphonic melodies, evolving sequences, and rich textures.
  • The SWN features six wavetable oscillators with independent pitch, level, and waveform controls.
  • Six LFOs (Low Frequency Oscillators) can be used as modulation sources and/or envelopes, making it easy to add dynamic motion to your patch.
  • Each channel is a full voice and can be “played” using the top row of buttons, the internal LFOs, or note-change detection on the 1V/oct jacks.
  • The SWN ships with 12 three-dimensional (spherical) wavetables and an easy interface which allows you to record and edit custom wavetables from live audio.
  • Open-source software for Mac, Windows, and Linux called SphereEdit can be freely downloaded and allows you computer to create, edit, and convert .wav files into Spherical wavetables to transfer into the SWN with an audio cable.

Many of our designs are open source.

Rather than replicate concepts from the past, we strive to turn unique ideas into playable musical tools that expand the possibilities of music.
