Help installing Pianoteq 6.2.1

Hello. I have an official license for Pianoteq. I would like to try to get it working on the Zynthian. I can’t find any references to how to install an update to the engine. Can anyone help?

Stage or Pro?
If Stage, did you try the webconf?

I should have clarified. I already own a copy of the Pro version, so that is the version that I have available to download from Modartt. I’ve read that it needs to be installed from the command line, but I have not been able to get it to work.

Pro ist not supported automatically yet, but Edward made it work.

Thanks! I’ll follow up on GitHub!
