I have had a bit of a debacle with Digital Performer and have had to Downgrade to an earlier version, which involved de-installing both 4.52 and 4.12.
When O try to load an instrument track I no longer have any of my plugs there as options (GPO, Storm Drum, Stylus RMX)
How can I get them back?
Someone suggested trashing the "Audio Unit info Cache" which would make DP search for all available plug-ins but it didn't work for me.
I also tried reinstalling the latest GPO 1.2 update but that didn't work either.
