OK, you guys convinced me to take a chance and install the 9.0 beta.
The download was a whopping 112 MB, quite large compared to most effects updates that are typically only 1-5 MB. However, it's still smaller than the 150 MB I usually download when Melda has an update. (It would be a greater advantage if I kept the free pack up-to-date, but I don't.)
Installation was not difficult, but it could be friendlier.
For example, it would be nice if the installer, instead of automatically selecting "ALL", would check to see what's already installed and just select those products by default. There are already shortcuts for selecting bundles, he could add one that says "Currently Installed". I still have to stop and think "now which ones do I have again?"
Also, the new installer did not preselect my previous plugin path, which would have resulted in duplicates had I not noticed. It put in "\program files\vstplugins\meldaproduction" as the default, when the old installer would have remembered that I use \program files\cakewalk\vstplugins\meldaproduction".
I ran a re-scan. Although that's not usually necessary for Melda stuff, I always do it anyway. I then brought up an existing project that had several Melda plugins in it. They all came up fine and remembered their previous settings, which was a relief.
Nice enhancement to MAutoDynamicEQ, adding attack/release/threshold to the expanded "Bands" section. I also noticed a CPU Benchmark feature under Settings - that's new, I think.
