Expert Sleepers 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.

There are currently 76 distinct algorithms ranging from envelopes and filters to resonators and vocoders.

mk4 version differences

• 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.
