Tooltips did not work with Dark Mode with Big Sur.
Workaround for the 'unusual' designed audio architecture of FL Studio. It is not longer necessary to enable 'Use fixed size buffers' to avoid crackles.
Workaround for a bug of Big Sur where new AudioUnits are only detected after a reboot.
Several small compatibility fixes for MacOS 11 and MacOS 12.
The coordiantes of the context-menu for knobs were not always correct.

The coordinates of the scrollbar-handle in the patch-browser could have an wrong offset.
A double-click to a knob of an envelope now correctly redraws the display.
Tooltips were not properly readable in some DAWs under BugSur with Dark Mode.
Automation in the VST3 version did not work with parameters that were located behind the 10th slot.
Workaround for a bug of Ableton and FL Studio which do not properly stick to the AudioUnit2 standard and did not display the AudioUnit.
Workaround for a bug of Reaper which does not display automation parameters incorrectly.
Workarounds for many DAWs which did not resize the VST3 plugin properly.


AudioUnit is now an AUv2 plugin.
AudioUnit and VSTi are now a Universal Binary for 64bit Intel and M1.
Apple's development tools are unable to build 32bit Intel binaries when you support M1. Sadly we had to drop support for it.
Apple's Notarisation and the M1 support requires a MacOS version higher or equal than 10.11. If you still use an older version you must stick with Icarus 2.0.
The name of 'Reverb Trance' is now 'Revereb Swirl'.

Breaking changes:

Please read this if you are on Mac and use AudioUnits. You can ignore it if you use Vst plugins or if you are on PC.
The AudioUnit interface had to be completely rewritten because of various issues that raised from the introduction of native M1 support and Apple's notarisation. It was not longer possible to keep AudioUnits downward compatible with reasonable effort.
As a result your old songs that used the AU version of previous Icarus versions will 'forget' their patches when you load them with Icarus 2.5.
You will have to re-select the patches and re-save your song or you might prefer to stick with the old version (
