I have these modules far enough along that I’ve decided to tag them as a “1.beta1.0”. I still have lots to do and there will be changes over the summer, but the module set is a good starting point. (Over the summer we will see more filters, more non-generic faceplates, and more performance and code improvements).
I have asked for the project to be added to the library builds (https://github.com/VCVRack/library/issues/565) but if you want to try the project, now that Rack ABI is stable, if you are using an appropriate version of Rack 1.0 you can download our nightly builds from here: https://github.com/surge-synthesizer/surge-rack/releases
We would very much value you’re feedback. GitHub issues are the best approach. I am going to be offline a bit for the end of June and start of July, but all feedback is useful.
EDIT: A rudimentary manual is now online at https://surge-synthesizer.github.io/rack_manual/
Thanks and look forward to hearing anything you find and - more importantly - hearing any music you happen to make with these modules!
