KarmaFX updates Synth Modular to v2.01

21st October 2021 - KVR Audio News

KarmaFX Synth Modular has been updated to version 2.01.

This release boasts several new features, including GUI improvements, MIDI Polyphonic Expression support (MPE), better HiDPI/Retina utilization on Mac/OSX, sound improvements and feature additions to the Chorus and SoftClip modules. It also contains some important bugfixes and performance tweaks.

Changes:

MPE: Added MIDI Polyphonic Expression support (MPE). MPE PB Range is configurable in NotePitch module and through MIDI RPN 0. (default is ±48 semitones).
MPE: Supports Low-Zone (Master Channel 1) and Off-mode, setup through MIDI MPE Configuration Message (MCM) or forced on in GUI.
MPE: Added Timbre option to Expression menu and to MIDIData module, in order to support MPE MIDI Control 74 (CC74).
Chorus: Added Width, Crossfeed and Feedback Delay parameters + tweaked Phase-panorama and Spread settings.
Chorus: Added option to apply filter to Chorus mix instead of feedback.
SoftClip: Added Digital Distortion to SoftClip module with Amount, Bits, Bias and Noise parameters. Renamed Trim to Drive and expanded range.
Distortion: Added Stereo option to Bits and Resampling Frequency knobs in Distortion module. Off by default.
Folder: Added Stereo option to Symmetry knob in Folder module. Off by default.
Sampler: Changed Sample selection knob in non-Multi mode to only switch sample on (re) trigger.
ADSR: Added Expression option to Sustain parameter in ADSR module.
NotePitch: Added MIDI note filtering through a Note Min/Max Basenote-parameter option in NotePitch module. Default is full MIDI range. (Thanks Daniel.).
MIDIData: Added Delta option, where controller events only pass inside note-on/note-off pairs and outputs delta, relative to value on note-on. (Thanks Dan.).
MIDIData: Added Bias and Smooth knobs to MIDIData module to optionally bias and lowpass filter incoming MIDI data.
SubPatch: Toggling a SubPatch module on/off will now resets its internal buffers and state.
GUI: Added HiDPI/Retina option to Options->Window Scale menu for enabling/disabling High Resolution utilization on Mac/OSX. (Thanks Jan.).
GUI: Mousewheel now works on knobs and sliders when hovering + Faster overall response, and holding Shift allows for fine-tuning.
GUI: Holding Shift key and clicking Options->Maximize/Minimize-All will now maximize and minimize only wave-displays.
GUI: The Options Window Size->Custom dialog initial values are now set equal to the currently chosen (non-scaled) resolution.
GUI: Enabled (Ctrl-Shift) debug menu on Mac/OS X (undocumented). Was previously PC only.
GUI: Exposed Patch Script loading option in debug menu. Can be used to author patches programmatically (undocumented).
GUI: Exposed option to show internal Debug Panel in debug menu (undocumented).
GUI: Exposed option to instantly toggle MPE in debug menu and to setup Global MPE ini settings (undocumented).
GUI: Holding left mouse on module caption for 1 second, now makes target module/knob LEDs blink (undocumented).
GUI: Throttled GUI FPS on PC/Windows to max 30 Hz (Same as Mac/OSX).
CPU: Improved performance in Osc1, Osc2 and LFO + Unrolled and inlined all parameter modulation processing.
CPU: Unrolled and inlined Chorus and MIDIData modules.
CPU: Expression parameters now only produce modulation-signals when Expression sensitivity is non-zero.
CPU: Granular inner loop is now SIMD optimized + Sample memblocks are now 16 byte aligned (in Sampler/Granular etc.).
CPU: Granular grains are now heap allocated and padded to be 16 byte aligned.
DOC: Updated manual to revision 0.36. Updated sections on MPE, Note filtering, Chorus, SoftClip (Distortion), ADSR Sustain, MIDIData and HiDPI/Retina.
Bugfix: Choosing Module Presets->Default did not reset parameter range-settings, tuning, etc. Fixed.
Bugfix: Cutting a parameter wire, by right clicking on wire arrow, would incorrectly shuffle volumes for other connections to the same parameter. Fixed.
Bugfix: Editing a Patch Description in Props dialog on PC/Win would only save the first 80 characters. Fixed.
Bugfix: SubPatch module would not store/restore subpatch-names correctly. Fixed.
Bugfix: Patch Browser toggle from SubPatch module was wonky and could crash the synth on GUI close. Fixed/rewrote toggle code.
Bugfix: Loading patch with SubPatch module in Adv-mode and touching bottom row of knobs would crash the synth. Fixed.
Bugfix: When using the "Insert" menu to create new module input, that connection could get lost on save/reload of patch. Fixed.
Bugfix: Saving a SubPatch could alter values for control panel parameters in parent patch. Fixed.
Bugfix: Switching Modulation view to see parameter modulation in wave-displays was not working. Fixed.
Bugfix: Resizing Scope module in "Phase" mode could crash the synth. Fixed.
Bugfix: The first sample in modulation blocks from Expression-enabled-parameters could be stale. Fixed.
Bugfix: Immediately after patch initialization, the first sample-block from a SubPatch Input module would have incorrect volume. Fixed.
Bugfix: Scope module Input1- and Input2-modes did not take into account the connection-wire-volume. Fixed.
Bugfix: Scope module would not work inside SubPatches unless connected to Output. Fixed.
Bugfix: Window size of GUI would not set up correctly for custom window-sizes in AU/VST version on Mac/OSX. Fixed.
Bugfix: Moved patch-loading-inside-GUI code into host Update callback and added Paint mutex to remove potential deadlock/crash.
Bugfix: Options->Maximize/Minimize-All would not update the GUI icon in the module headers. Fixed.
Bugfix: Maximizer module would not recover from overflow mode, even when reset. Fixed.
Bugfix: Maximizer module would muffle volume of processed audio immediately after init or reset. Fixed.
Bugfix: Unhooking volume-slider from modulation sources would not update its GUI-state. Fixed.
Bugfix: Removed excessive internal ramping of ModIndex in FM module.
Bugfix: Sampler could cause read-access-violation in multi-sample-mode with memory-guards enabled. Fixed.

Bugfix: Waveform GUI mouse-drawing in Additive and Pad modules was broken on Mac/OSX. Fixed.
Bugfix: Cancelling a menu-triggered patch-load operation inside a SubPatch, would leave the synth in a state unable to load patches. Fixed.

Bugfix: GUI Magnitude and Phase bars in Additive module did not align with mouse-y-position. Fixed. (Thanks Dan.).
Bugfix: Internal sorting of MIDI-events could read out-of-bounds on ring-buffer wrap(1024), causing corrupt, phantom MIDI-events. Fixed. (Thanks Dan & Shane.).
Bugfix: Filter keyboard tracking did not smoothly track input frequency. Fixed. (Thanks Dan.).
Bugfix: GUI Resize on Mac/OS X did not update mouse tracking region, causing MouseMove-events to not get passed after resize. Fixed. (Thanks Dan.).
Bugfix: Unison's stereo Pan knob was incorrectly working in Mono-mode. Fixed. (Thanks Dan.).
Bugfix: Frequency Snap to Semitones and Octaves did not work for extreme values, due to ramp interpolation of parameters for very small deltas. Fixed.
Bugfix: Cloning a module in GUI did not clone parameter-flag-settings such as Osc1 "Random Poly Phase", "Phase Init Only" etc. Fixed.
Bugfix: Having two chained NotePitch modules, where one is Polyphonic and the other is Monophonic did not work polyphonically. Fixed. (Thanks Dan.).

Bugfix: Mouse GUI cursor did not always update correctly on Mac/OSX. Fixed.

Bugfix: Amplifier voices would not always reset when quickly switching NotePitch poly-mode. Could cause hanging notes. Fixed.
Bugfix: Noticeable lag when flipping through patches containing active Pad modules, due to wait for Generate-thread to complete. Fixed.
Bugfix: LFO with Random-waveform (RND/RND16) did not always wrap correctly in non-trigger mode. Fixed.
Bugfix: Latency compensation timing was off by 256 samples. Fixed.
Bugfix: Granular Shape curve was biased too much towards rectangular grain-shape. Fixed.
Bugfix: Granular output was not double-buffered in GUI. Fixed.
Bugfix: Granular would not initialize with correct sample Pos in "Manual" mode. Fixed.
Bugfix: Fixed minor discrepancy in equal power panning. Rescale is now sqrt(0.5) as opposed to truncated 0.707.
