16-in-1 multifunction module

From May 2015, the disting has been updated to a 'mk2' version. Compared to an original ('mk1') disting, the only change is an increase in the maximum delay time of the Clockable Delay/Echo mode - more than doubled to over 1.6 seconds.

The Disting is a 16-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 included algorithms are:

• 1A: Precision Adder with integer voltage offsets.
• 1B: Four Quadrant Multiplier with integer multiply/divide.
• 1C: Full-wave Rectifier.
• 1D: Minimum/maximum.
• 2A: Linear/Exponential Converter.
• 2B: Quantizer with selectable scales.
• 2C: Comparator with adjustable hysteresis
• 2D: Dual Waveshaper wavefolder and triangle-to-sine shaper
• 3A: Sample and Hold with noise source and adjustable slew rate
• 3B: Slew Rate Limiter with linear and exponential slew
• 3C: Pitch and Envelope Tracker
• 3D: Clockable Delay/Echo
• 4A: LFO with through zero frequency control and waveshaping
• 4B: Clockable LFO with multiply/divide and waveshaping
• 4C: VCO with linear FM sine and saw outputs
• 4D: VCO with waveshaping saw/triangle and pulse outputs

The Disting's specifications are as follows:

• X & Y inputs, A & B outputs
• Sample rate: 78.125kHz
• 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: 10kHz approx
• CPU: Microchip PIC32MX at up to 40MHz

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 10 way IDC, with -12V furthest from the top of the board.

For more detail, please see the user manual.

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.
