The Expert Sleepers Disting Mk4 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.
