disting mk4, front disting mk4

The disting is a many-in-1 multifunction module, offering a variety of CV and audio processes, including a selection of oscillators (LFOs/VCOs). All algorithms have two high-precision inputs and outputs, and a third control input, exposed on a front panel knob and a CV input.

The disting is also a sample (WAV) file and MIDI file player, with a variety of options for sample triggering, playback speed etc.

Video review by loopop:
The disting mk4 was reviewed Waveform Magazine (issue #1).
“I have found this to be a super helpful and versatile module. Unlike many multi- function gadgets in the music gear world, the Disting MK 4 does a lot, and does it all well. You could literally build a complete system out of only Distings. It’s affordable, easy to update, has an amazing manual, a mountain of demo videos, and is only 4HP. I say this with no hyperbole: I want at least 4 Distings in my setup.”
The disting mk4 was favourably reviewed by Ask.Audio - read the full review here.
“Incredible range of functionality in a tiny size”
The disting mk4 was awarded a 'Sonic Joy 2017' award by AudioNewsRoom - read all about it here.
“Hard to find something it doesn’t do!”
The disting mk4 was awarded an 'Excellence' award by MusicTech Magazine (November 2017 issue) - read the full article here.
“To have all of this functionality at such a sensible price point makes this an absolute bargain.”
AudioNewsRoom gave the disting mk4 4.5 stars (out of five) - read the full review here.
“I would say this Disting Mk4 is a no-brainer: an essential piece to add to your Eurorack!”
A thorough review (in German) of the disting mk4 appears on BuenasIdeas here.
“Zumindest mir persönlich ist kein anderes Modul bekannt, dass mit einer derartigen vielseitigkeit im unmittelbaren Zugriff aufwarten kann, insbesondere auf lediglich 4 TE und zu einem für ein besseres Eurorack-Modul vergleichsweise günstigen Verkaufspreis.”

The disting mk3 was awarded an 'Excellence' award by MusicTech Magazine (June 2014 issue).
“With so much functionality on offer, this unit is something of a no-brainer.”

The disting mk3 was also nominated in MusicTech's Gear Of The Year 2016 poll.

The disting mk3 was awarded 'Value' and 'Platinum' awards by Future Music Magazine (July 2014 issue).
“Unquestionably the most useful module in Eurorack. We don’t think there’s any system that wouldn’t benefit from having at least one.”
The disting was selected by to be part of their core training rack.

The video below was the winning entry in a video competition we held to promote the original disting. It's a fun and very musical romp through the first 16 of the disting's functions.

mk4 version

The disting mk4 was introduced at the NAMM show in January 2017. The main differences compared to the disting mk3 are:
  • Dot matrix screen, capable of showing text and numeric values
  • Micro SD card slot accessible on the front panel
  • Compatibility with the Select Bus protocol
  • An internal precision clock allowing new algorithms such as a tuner, and pitch and frequency references
  • MIDI in/out ports (on a breakout header)


The disting mk4's specifications are as follows:

  • Panel width: 4HP
  • Module depth: 42mm
  • X & Y inputs, A & B outputs
    • Sample rate: 75kHz
    • ADC: 24 bit, THD+N -93dB, Dynamic range 99dB, SNR 99dB
    • DAC: 24 bit, THD+N -94dB, Dynamic range 105dB, SNR 104dB
  • Z input sample rate: 75kHz
  • CPU: Microchip PIC32MX at up to 50MHz
  • Current draw: 51mA on the +12V rail, 19mA on the -12V rail

The front panel is drilled for both Doepfer and Analogue Systems mounting holes (using a 'slot' rather than a single round hole). The power connector is a Doepfer standard 16 way IDC, with -12V furthest from the top of the board.

For more detail, please see the user manual.

Pricing & Availablity

The disting mk4 is available now.

MSRP: UK £169 (inc VAT), US $195 (exclusive of sales tax), EU €164.07 (exclusive of VAT)

For purchasing links, please see where to buy.


The disting is based around a PIC microcontroller, with a programming/debug header available on the board. Using Microchip's free development tools a user can easily hack the disting to perform their own functions.

We have provided an open source code framework into which developers can slot their own algorithms. This can be found here. There is a thread about disting firmware hacking on the forum here.

Below is a (rather long) video introducing the disting in some detail, filmed at a meeting of the London Music Hackspace. You may like to jump in at these times:

  • 06:00 - description of the hardware
  • 40:45 - description of the open source software framework
  • 1:16:45 - compilation of some custom code and seeing how it sounds.
