It admittedly confused me for a bit (and I almost gave up) as the reference to the “Installer” is what I thought was done exclusively by the “product manager”, so I thought that it was within that. I did finally realize that an installer (specific to EZkeys) was installed, and followed your instructions from there. I am denoting these points just in case someone else reads this in the future and needs clarity as well.
If I may ask, do you happen to know why ToonTracks does not natively install the plugins for EZkeys (as they do for EZdrummer 3 & EZbass (just curious)?
