Basically logic 7 doesn't support waves and loads of other AU plugins .
TDM plugins work fine
DTDM don't.
Apple never told anyone about this problem and I just paid £200 to upgrade but I cant work .
Its disappointing but was expected after Apple took over.
Maybe its time to find another Sequencer with another computer .
I just spend over 25k on a new HD3 accel, bought loads of plugins and a G5 2ghz 2gig Ram.
I have seen some manufacturers have already begun fixing the problem but apple are irresponsible releasing a 'pro' program to the market but not warning anyone about this problem. Most of us "pro's" use 3rd party plugins and instrument and if I had known about this problem I wouldn't have bothered upgrading. (Now Im back on logic pro 6.4.2).
