Disting mk4

Many-in-1 multifunction module

THE disting mk4

The mk4 builds on the previous mk3 and adds these new features:
- a dot matrix display, making menu navigation, parameter selection etc. a breeze.
- a front panel accessible MicroSD card slot.
- compatibility with the Macro Machines Storage Strip.
- an internal precision clock allowing new algorithms such as a tuner, and pitch and frequency references.

The new version is largely software-compatible with the mk3, and the intention is to continue releasing new features for both the mk3 and mk4 in parallel.

X & Y inputs, A & B outputs:

• ADC: 24 bit, THD+N -93dB, Dynamic range 99dB, SNR 99dB
• DAC: 24 bit, THD+N -94dB, Dynamic range 105dB, SNR 104dB
• Sample rate: 75kHz
• Z input sample rate: 75kHz

CPU: Microchip PIC32MX at up to 50MHz, hackable, open source code framework available.

There are currently 84 distinct algorithms organised in several banks.
The first 16 are the 'classic disting' ones.
