This update makes Classic FX a universal iOS and macOS application. Now Classic FX can works on iPhone and iPad as well as Mac / MacBook with M1 chip (and later). On macOS this application can works both as a standalone and as an Audio unit (AUv3) with DAWs and audio unit hosts like Ableton Live, Logic Pro, GarageBand, MainStage, Plogue Bidule, etc. All application features are available on macOS.

- Added fullscreen mode when using the plugin with GarageBand (iOS).
- Optimization of the audio engine.
- Some improvements and fixing a few minor bugs.
- Built-in description has been updated (also available as PDF file on the application site).

In this update a new LFO option has been added for automating morphing between the two effect slots A and B. Now you have three linked LFOs to create more complex waveforms to modify the morphing. Or you can use one LFO for simple automation. Each LFO has two ranges, fast and slow and two types of waveforms. You can set the LFO frequency in beats synchronized with the main BPM, or in seconds. Also you can see the final waveform of all the LFOs on a graph at different scales.

This update brings six new processing algorithms based on reverse delay, saturation and distortion. These new algorithms Back Talk, Bitcrusher, Oversaturate, Gated Echo, Gated Reverse and Shining will give a completely new sound to any instrument or voice, from soft saturation and ambient fuzziness to sharp and hard overdrives and bit reduction.
