Expert Controller Plus
The ‘Preview’ phase (version 0.1) has now concluded. Thank you to all those who provided feedback.
If you would like to get involved in testing and provide feedback please drop me a message using the Contact page on this website. For more information about Expert Controller Plus see the Software and News sections of this website.
The project has now entered a Test phase. The first production-ready release is anticipated in quarter three of 2026. All planned features have now been implemented but testing and feedback is needed from users, especially those with an Expert 1K-FA as I don’t have hands-on to that model and it implements a very different interface to all later amplifier models.
