Kilohearts rolled out full AAX support today. They call it a public BETA, but it has no known limitations.
More kHs ONE presets
The kHs ONE polyphonic synthesizer has been updated with ~150 presets, for a total of about 500 factory presets.
Preset support in Snapins
Kilohearts snapin lineup have been updated to include presets individually. All snapins now have an expandable settings panel where you can save and load presets, as well as reset to the init patch. There is also a Randomize button that scrambles the current patch.
