Description
Introduction
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.
Functions
There are currently 84 distinct algorithms. The first 16 (‘classic disting’) are:
- Precision Adder with integer voltage offsets
- Four Quadrant Multiplier with integer multiply/divide
- Full-wave Rectifier
- Minimum/maximum
- Linear/Exponential Converter
- Quantizer with selectable scales
- Comparator with adjustable hysteresis
- Dual Waveshaper wavefolder and triangle-to-sine shaper
- Sample and Hold with noise source and adjustable slew rate
- Slew Rate Limiter with linear and exponential slew

- Clockable Delay/Echo
- LFO with through zero frequency control and waveshaping
- Clockable LFO with multiply/divide and waveshaping

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)
Specifications
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.
Hackable
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. Note though that this framework has not yet been updated for the mk4 version.
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:
