Fixed a crash when loading the Poly Wavetable algorithm after the SD 6 Triggers algorithm was previously used.
Fixed preset loading for the Poly Wavetable algorithm.
In the Augustus Loop algorithm, fixed the delay time changing when 'Inertia free' was activated.
Wavetable algorithms now support 32 bit float format WAV files, and default to interpreting single file wavetables as having a 2048 frame wavelength if the file is a multiple of 2048 frames in length. (Together, these changes mean that Serum format wavetables are natively supported.)

Added the Poly Wavetable algorithm.

It is now possible retrigger loops in the Looper algorithm without first pausing them.
Added a 'Transpose limit' setting for the SD Multisample algorithm.
Added 'MIDI learn' for setting up MIDI mappings.
Added a SysEx interface to parameter discovery and editing, allowing remote preset editing over MIDI.
Added a 'Chromatic' scale type for the SD Multisample algorithm and fixed the 'Natural Minor' scale so playing notes actually in the scale produces the correct result.
A preset can now store the index of a mapping to load automatically when the preset is loaded.
The 'Show MIDI history' display now shows all messages (was previously blank for clock etc.).
When selecting dual mode parameters via encoder push-hold-turn, the display now remains in zoom mode as long as the encoder is held.
Fixed a bug in the Wavetable VCO, Dual VCO, Pulsar VCO, and Dream Machine algorithms which would cause unpleasant aliasing distortion, especially at high pitches.
Fixed a possible crash when switching from dual to single mode.
Fixed a bug in the MIDI File Playback algorithms which could corrupt playback of files over a certain size.
Added the Dual VCO algorithm.

Added the Dream Machine algorithm.
Added the Filter Bank algorithm.
Incorporated disting mk4 firmware version 4.17 (so adding the Rotary and Clock algorithms).
Added the Looper 'Octave down' function.
Added Looper-specific i2c messages.
Added hysteresis to knob mappings to avoid jittery behaviour.
Added settings to enable automatic switching of the current parameter to the one being changed by MIDI or i2c.
All MIDI transmit channel settings can now be set to 'Off'.
All single mode algorithms that respond to MIDI notes can now be set to ignore them.
The dual mode Quantizer algorithm now uses the MIDI receive channel from the settings.
Reduced the default fadeOut setting for the SD 6 Triggers algorithm (to reduce trigger latency).

Added the "Default first CC" setting.
