We just uploaded to the Phausto repository an upgraded version of the dynamic-engine for Apple Silicon. Using native CoreAudio as driver it improves stability by eliminating PortAudio known issues. A custom modification of the orginal dynamic-engine allows to use MIDI to control DSPs that have defined UI parameters labeled gate , freq and gain. This means external MIDI keyboards and sequencers can be used to play polyphonic synthesisers created with Phausto.
