See the previously posted table: the limitation completely depends on what plugins you are running at a time. You might be only able to run a few mastering plugins at a time, but you would get tens of equalisers for example.scuzzphut wrote:Project Pak - £349
So - what are the limitations on the number of plugins the hardware will run simultaneously ?
The unfortunate limitation with project pack is that you will only get the most basic and generic sounding plugins and you have to individually buy the good ones.
Generally people seem to buy the project pack as an additional card to run alongside the ultra pack, thus doubling the DSP power.
) On the other hand quite many people at the UAD forums have the same issues. However, i wouldn't know what kind of host specific issue could cause a plugin to use much more CPU than usual. Since i took part in developing the host i'm using as well as having tested almost every Plugin i could find in it, i have seen lots of denormal related issues. Of course i can be wrong but the issue i do have smells a lot like any other denormal problem.
What are you using to monitor native CPU usage per plugin? Is this in the host app itself, as it plays back that you are able to measure each plugins CPU usage? I don't use anything that sophisticated. I do use a little system CPU/RAM monitoring utility (FreeMem Pro). It places two tray icons (CPU & RAM meters),in your taskbar. The way I measure the UAD-1's native CPU usage, is to make note of a projects CPU usage, as it plays back without any FX plugins. Then when I add 6,8,10,16 or 24 UAD-1 plugins, I'll compare the native CPU usage difference, using my FreeMem Pro meters. I will see anywhere from 2%-5% added native CPU increase, in SONAR 4.02, after adding my UAD-1 plugins, which is fairly typical, for most UAD-1 users.
Severe native CPU munching when using more than 4 or 5 UAD-1 plugins, at a time. I can have a (10) track audio project with no FX plugins, using about 15%, of my CPU, but once I add 6 UAD-1 plugins my CPU usage zooms to 75% (60% added native CPU usage, for only 6 plugins)
