4.8 19/9/2018
  • In this release there have been extensive and low level changes to all parts of the code accessing the SD card. Please be vigilant for related issues.
  • All Audio Playback algorithms now use folders to organise their sample files. Playlists are no longer required (but may optionally be used to set file options). Algorithm-specific playlists are no longer used.
  • The Wavetable VCO algorithm no longer uses playlists inside wavetable folders.
  • The Audio Recorder algorithm now stores its recordings inside a folder.
  • All Audio Playback algorithms (with the exception of Audio Playback with Scrub and Audio Playback with Crossfade) now have an 'Env time' parameter, allowing the sample playback to be gated by the trigger input, with optional decay envelope.
  • All Audio Playback algorithms with trigger inputs can now be triggered by MIDI notes. Additionally, the Audio Playback with V/Oct and Multisample Audio Playback algorithms use the pitch of the MIDI note for the sample pitch, so you can simply play the disting like a sampler from a MIDI keyboard.
  • The Audio Playback with V/Oct and Multisample Audio Playback algorithms support polyphonic operation (one disting mk4 per voice) when triggered by MIDI.
  • The disting mk4's Select Bus will now respond to all MIDI not specifically part of the Select Bus protocol as if the MIDI had arrived on its MIDI port, meaning the Select Bus can be used as an additional MIDI input, potentially shared by a number of disting mk4s on the same bus.
  • Added the Audio Playback with Crossfade algorithm.
  • Added the Mono Audio Recorder algorithm.
  • Added the Quantizer 2 algorithm.
  • Added 'Sum Mode' parameter to the Precision Adder algorithm.
  • Removed the 'with push' variants of the AR Envelope, AR Envelope & VCA, and Dual AR Envelope algorithms and incorporated the Z knob push functionality into the remaining variants (since parameter selection can now be down by push-turning the S knob).
  • Added 'Offset A' and 'Offset B' parameters to the AR Envelope, AR Envelope & VCA, and Dual AR Envelope algorithms.
  • Added the '-playToCompletion' and '-useStartOnSampleChange' WAV file playlist flags.
  • Added an 'Offset' parameter to the Sample and Hold, and Dual Sample and Hold algorithms, to correct for timing variation between the sample trigger and the CV being sampled.
  • Added independent control of up and down slew times to the Slew Rate Limiter algorithm.
  • Added control of clip/saturation mode and an optional LFO output to the Crossfade/Pan algorithm.
  • Added a setting to continuously scroll WAV and MIDI file filenames, rather than displaying them once and then reverting to the algorithm name display.
  • Added a setting to control the speed at which text scrolls across the display.
  • Improved the performance of the Dual Audio Playback algorithms when triggering both samples together.
  • Fixed the Dual Audio Playback with Z Speed algorithm so both samples may now be chosen as the same file without audio corruption.
  • Fixed a problem with slew in the Programmable Quantizer algorithm where the pitch CV would never reach its intended final value.
  • Fixed a problem with the Mono-to-Stereo Reverb algorithm which could cause excessive noise in the reverb output when nothing was driving the feedback CV (Y) input.

4.7 4/7/2018
  • Added the Multisample Audio Playback algorithm.
  • Added MIDI Gate parameter to the Shift Register Random Quantized CVs, Quantizer, and Dual Quantizer algorithms.
  • Fixed the quantization of natural and harmonic minor scales so that incoming notes already in the scale don't get shifted to neighbouring notes.
  • Fixed an issue in the Dual Euclidean Patterns algorithm that could cause it to start incorrectly depending on the position of the Z pot.

4.6 24/4/2018
  • Added the Delayed LFO algorithm.
  • Added the Scaled LFO algorithm.
  • Added the Gate algorithm.
  • Turning the S encoder while holding it in now selects the current parameter; it no longer changes algorithm.
  • Added Multiplier & Pan parameters to the Clockable Ping Pong (Z feedback) algorithm and Multiplier & Out Mode parameters to the Clockable Ping Pong (Z input pan) algorithm.
  • Added Multiplier & individual output attenuverter parameters to the Clockable AD Envelope algorithms.
  • All envelope attenuverter parameters now use the range ±32.
  • Added an output mode parameter to the Clockable Delay/Echo and Tape Delay algorithms.
  • Added coarse and fine control over tape length (effectively delay time), calibrated in milliseconds, to the Tape Delay algorithm.
  • Increased the range of the Offset parameter in the CV/MIDI Algorithm.
  • Added DC-blocking filters to the input(s) of the Reverb algorithms.
  • The MIDI Clock algorithm now stops generating clocks if it receives a MIDI Clock Stop message but MIDI Clock messages continue to arrive.
  • Added a MIDI CC to restore control of Z to the knob/CV, if it had been previously taken over by MIDI.
  • Improved performance of the Dual Audio Playback algorithms.
  • Preset 0 now saves the selected favourite (O1-P8) algorithm if used, rather than the actual algorithm that the favourite refers to.
  • Fixed a crash in the Linear/ Exponential Converter algorithm when Z was at the negative end of its range.

4.5 19/2/2018
  • Added Audio Playback with Reverse, Audio Playback with Scrub, Dual Audio Playback, and Dual Audio Playback with Z Speed algorithms.
  • Audio playback algorithms now support up to 100 files per algorithm.
  • The Wavetable VCO algorithm now supports up to 100 wavetables.
  • Improved UI responsiveness when in audio playback modes.
  • Algorithm selection can now loop from P-8 to A-1 and vice versa.
  • Fixed a problem where the disting might stop receiving MIDI if MIDI was being sent into the module while it was powering up.
  • Fixed a problem where the B-8 VCO mode might change pitch unexpectedly while adjusting parameters.
