Expert Sleepers Disting mk4

  • $189.00


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 63 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
  • Pitch and Envelope Tracker
  • Clockable Delay/Echo
  • LFO with through zero frequency control and waveshaping
  • Clockable LFO with multiply/divide and waveshaping
  • VCO with linear FM sine and saw outputs
  • VCO with waveshaping saw/triangle and pulse outputs 


The remaining algorithms are:

  • Precision Adder with fractional voltage offsets
  • Voltage Controlled Delay Line vibrato/chorus/flange effects
  • Clockable Ping Pong Delay
  • Clockable Ping Pong Delay with input pan control
  • Resonator for drum synthesis
  • Vocoder 12 band

The functions relating to playing back audio and MIDI files from the MicroSD card are:

  • Audio Playback
  • Clocked Audio Playback
  • Audio Playback with V/Oct
  • Audio Playback with Z Speed
  • MIDI File Playback (Clocked)
  • MIDI File Playback (Free Running)
  • Audio Playback with End CV

 

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


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.

It is our intention to provide an open source code framework into which developers can slot their own algorithms.
