SpectrumWorx

This version adds Audio Units support for Mac OS X. Both OS versions have been updated with several sound fidelity, stability and performance improvements.

This version adds Octaver module, improves pitch shifter quality, and significantly reduces memory consumption. Both OS versions have been updated with several stability and performance improvements.

This version adds frequency range, gain and dry/wet controls to each module separately, all available from the main plug-in window. This addition significantly increases usability and makes the plug-in capable of producing subtle sound effects easier. Both OS versions have been updated with significant performance improvements.

This version adds Freeze and Convolver modules, and a 50-preset signature bank created by Syndicate Synthetique, thus representing a major update. Both OS versions have also been updated with stability and performance improvements.

* added:
- "Gamma Shift", signature preset bank by Martin Walker
- automatable LFOs
- new module parameter control: symmetric knob

* fixed:
- hosts are now correctly notified of automatable parameter changes when modules are added, moved or removed
- LFO waveform icons alignment
- default positions of the "In" and "Out" main editor knobs

* improved:
- more descriptive unit text for the Frecho Rate parameter
- more descriptive LFO section of the GUI
- overall efficiency improvements and binary size reduction

* added:
- LFO phase adjustment
- new module: "Frevcho", reversed frequency domain echo
- new LFO waveforms: random and glide ("Grandom"), chaotic random ("Whacko"), impuls up and down ("Dirac up", "Dirac down")
- 10 presets

* removed:
- automatic "Band Pitch Shifter" to "Pitch Shifter" compatibility translation for old presets

* fixed:
- no GUI in DSP Quattro
- incorrect Burrito operation for non-mono input
- incorrect LFO period snapping for triplet and dotted notes in the range between one beat and one bar duration
- changing the tempo or the time signature no longer alters the period of free LFOs
- LFOs are now correctly updated with time signature changes
- enabling an LFO for a parameter now blocks automation for that parameter (instead of the previous one)
- presets that were not updated with PVD Pitch Spring changes in version 2.2
- presets that loaded an external audio sample without actually using it
- interpretation of the host provided VST time position information, SW no longer strictly follows the VST 2.4 standard in this regard but this seems to work better with major hosts (e.g. SW LFOs will no longer run twice as fast when you switch from a quarter based to a quaver based meter in Reaper, Live or Cubase)
- renamed random and hold LFO waveform from "Random" to "Hrandom"

* improved
- echoed signal in Frecho is not low-passed
- waveform icon for random and hold

This version brings the much awaited "tempo-synchronized LFOs" feature and more presets, totaling 145. Both OS versions have been updated with stability and performance improvements.

* added:
- Mac OSX 10.5 and 10.6 support
- Preset browser "SaveAs" functionality

* removed:
- Preset browser "Revert" functionality
- ".swp" preset file extensions from the Preset Browser display
- the "Pitch Shifter" module:
- renamed the "Band Pitch Shifter" module to "Pitch Shifter"
- existing presets with the "Pitch Shifter" module will load correctly except that SW will warn you about missing start and stop frequency parameters, simply dismiss the warnings and press "Save" (to update the preset with the new Pitch Shifter setup)
- SW will handle existing presets with the "Band Pitch Shifter" module and will load them with as if they referred to the (new) "Pitch Shifter" (please update your affected presets as this special handling may be removed in a future version)

* fixed:
- Frecho: dry signal leakage
- crashes and/or lockups when automating global parameters
- lost automated parameter changes when rendering
- deadlock in Reaper when in demo mode
- hosts are now correctly notified about SW IO mode changes (including during project loading)
- changed the Overlap factor parameter to take only power-of-two values thereby eliminating modes with inherent audibile artefacts

* improved:
- slightly polished exported parameter name generation
- new preset name generation (name of the current program instead of simply "current")
- significant overall speedup (up to 15%) and binary size reduction
- minor system resource usage reduction (SpectrumWorx no longer spawns unnecessary threads)

* known issues:
- Mac: Audio Mulch 2.1, Studio One 1.6.0 and Live 8.2 (on OS X 10.5) are known to crash if closed while a SpectrumWorx GUI is open with one of the auxiliary windows (Settings and/or Preset Browser).
- Mac: Live 8.2 is known to crash when loading a project file with a SpectrumWorx instance that tries to set a non-default IO mode.
- Mac: real-time LFO knob animation uses a lot of CPU power (until this is fixed you can workaround the issue by changing the LFO update GUI option to either never or only for selected/active controls).
- Mac: SpectrumWorx GUI does not work in Audacity.
