Thank you midi lance!! I have WAY to many custom preferences setup to completely blow away my DP8 preference folder, so this didn't work for me. HOWEVER.... I experimented with adding the plugins in on-by-one to see which ones were really causing the problem. Surprisingly, all of the new instruments seem to work fine, but 2 of the classic instruments consistently crash DP8 every single time:
1. MINI V
2. Prophet V
So this is what worked for me:
Remove ALL of the Arturia V Collection 4 components from the /Library/Audio/Plug-Ins/Components
Then add them back one-by-one starting DP 8 between each plugin addition (this allows DP to add them to the AU cache one at a time)
DO NOT add the following plugins:
1. Mini V2 Efx.component
2. Mini V2.component
3. Prophet V2.component
This should allow you to run all of the Arturia V Collection 4 plugins EXCEPT the Prophet and Mini. One other drawback to this workaround is that during AU validation (even for the plugins that are 'working'), several of the Arturia instruments issue a warning indicating that degraded performance (latency) will likely occur. I'm not sure what this means exactly, and I have not as-of-yet had a chance to play all of the plugins, so I can't report on their performance. I can tell you however that the new Matrix V plugin consumes an INCREDIBLE amount of CPU. I have a very powerful Macbook Pro with a 4Qi7 and 16GB of RAM and a single instance of Matrix V consumes 25% of my CPU to play a single note!! It does sound amazing however, so I am hoping that Arturia can provide some patches that address the performance.
In general, I would consider this a hack at best, and I am very disappointed with Arturia for the sloppiness in this release. I really need my Prophet and MINI back as these are the two plugins that I rely on the most. PLEASE provide a fix for the V Collection 4 ASAP!!!
