Yes fellas, it is a Cakewalk problem... I've been stranded with DXI using UA's v3.9.0 for the longest due to this very reason (one of many)....
When using DXI, I have no problems whatsoever... UA's decision to drop DXI support was one of the worst things to ever happen in my recording career....
On Sonar 6, I have the option of using either DXI or VST; before deciding to make the jump from something that I know works well to the uncharted depths of the unknown, I used the VST versions of the plug-ins in v3.9.0 to see if they were full of problems...
To my dismay, I found the LA2A & Precision Limiters' intitial defualt settings in the VST format to be so horrible, that they bordered the point of comedy... Other plug-ins had issues as well...
The only thing I could think of to deal with this problem was to make FXPz of all the default settings of the DXI versions of the UAD-1 plug-ins... After doing this, I bring them up as VST versions, click on the VST icon and load the FXP into the plug-in... In order to bring up this setting every time a load the respected plug-in, I click on it's disk icon so it is a saved preset... I just simply name them 'default'...
If you guys want, I'll upload the file I made with all the presets...
As of now, it features only the plug-ins from version 3.9 and earlier, but I plan on going to my friend's studio (who uses Nuendo) in a few days and saving all his default settings for the newer plug-ins as FXPz as well, so when I make the jump to version 4.7, that'll be one less thing to piss me off...
Expect to see me make other posts in regards to the many problems the Sonar/UA situation have created....
