In the coming days I will be making a preview release of my upcoming ‘SPE Expert Controller Plus’ macOS App available to anyone who would like to give it a try. As a preview it is incomplete, has had no rigorous testing and undoubtedly contains defects but it has many of the key User Interface elements and functionality I expect in a later public release.

The current build appears to work with my 1.3k-fa using a serial or network interface and incorporates support for multiple simultaneous connections with amplifiers, partial Expert 1k-fa support (work in progress), Accessibility / Voiceover and much other core functionality.

I’m making it available using Apple Test Flight so you will need that free App from the App Store and I’ll need the email address you use with the App store so that I can make it available for your download. As work continues and subsequent preview releases are made, Test Flight should let you know a later version is available for download.

Some important caveats

• It requires macOS 14 or later – it hasn’t been tried on macOS 26 yet
• It should work alongside the original SPE Expert Controller App
• All settings, including the definition of Connections, Groups etc do not persist between App launches. I’ve done this to simplify the roll-out of future preview releases. Storage will become persistent once the App has matured somewhat.
• It sends request commands to an Expert 1k-fa but doesn’t yet have any processing of received responses.
• It hasn’t been tried with more than one simultaneous connection.
• There is no help documentation but drop a message and I’ll try to assist.

If you are curious and wish to give it a go drop me a message using the Contact form on this g0rvm.uk website. I’m certainly interested to hear how you get on and what you think but don’t be surprised if something doesn’t work as it’s still early-days.
