Expert Sleepers Disting Multifunction Eurorack Module (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.

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.
