Veli-Pekka, good to see you are still around!

With regard to Nord Modular screen-reader compatibility, did you hear about the Nomad project to build a open-source NM editor in Java? This project is aimed mainly at trying to make sure there is still a editor for a discontinued synth as well as facilitate Linux usage but if Clavia's version doesn't work that one might and if not the developers can at least be notified of the issue.

It's a beta and it has bugs but it might be worth a try. I have no idea how a screen-reader would work with visual cables but I have worked with the NM since it came out and for what it does the NM is a excellent platform for sound-design.

It's a small chance but I hope it helps,
yours,
Kas.
