I am currently evaluating the demo of S1 3.5.3, comparing it to Cubase. I am a longtime Sonar user - 'nuf said.
The tests I have been running show S1 to have very good audio engine performance, especially with Dropout Protection enabled. However, there is one scenario where I am finding it to perform quite poorly - when UAD plugins are in the project. It doesn't crash, it just puts a substantial strain on CPU resources.
I am using a modified version of the popular DAWBench 2017 test. Without getting too far into the weeds, this test focuses on 40 tracks, each with a simple sine wave audio file, and 4 instances of a free, relatively high CPU plugin called SGA1566. The key is to see how many of these instances can be activated before dropouts or glitches occur. I have added two "UAD 1176 Rev. A" plugins on each of 17 tracks, plus one "UAD Precision Multiband" on one track just to see how S1 deals with the excessive latency of this plugin. This just about maxes out my UAD resources. Cubase handles this test far better than S1. Here is a sample of my results:
|Cubase no ASIO Guard
|Cubase Normal AG
|Studio One no Drop.Prot.
|Studio One DP Lo (256)
|Studio One DP Med (512)
Bottom line - without ASIO Guard or Dropout Protection, Cubase allows for almost 50% more instances of SGA1566 while the UAD plug-ins are inserted. With ASIO Guard/Dropout Protection the difference is about 40%. When I run this same test without the UAD plugins, S1 and Cubase are virtually identical, although S1's engine is much smoother when jumping around the timeline or looping. I really like S1's interface and super-smooth audio engine, but I have a lot invested in UAD, so performance with UAD plugins is critical for me. I am wondering if anyone has any suggestions or a different experience.
Incidentally, I also got major crackling when trying to use a buffer size of 128 with UAD plugins enabled. I have never had this issue in any other DAW software (Cubase, Sonar, Reaper, Vegas). This is particularly bad as 128 seems to be the sweet spot for my audio interface.
