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.

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.
