This page describes the legacy mk3 disting. For the current product, please see here.


disting, front disting
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 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 disting. It's a fun and very musical romp through the first 16 of the disting's functions.

mk3 version

The disting mk3 was introduced in November 2015. The main differences compared to the original disting are:
  • Smaller - now 42mm deep (from 53mm)
  • Over 50% less power consumption - now 70mA combined draw (from 148mA)
  • User-updatable code - via Micro SD card
  • More algorithms - no longer limited to 16
  • More functionality - new encoder and push buttons give more control options


The disting mk3'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: 50mA on the +12V rail, 20mA on the -12V rail (70mA total)

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 mk3 is available now.

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.
