I am currently running a C3500 surface with the 64x64 Dante card installed in the back. I was thinking about trying out Waves Super Rack Performer and using the Dante card for the processing.
My computer should be able to handle the processing just fine but I was wondering if anyone here has tried this method and if the latency got to be to much to handle? I wouldn’t be using a plethora of plugins but would like to supplement the console.
It’s going to be pretty latent due to the fact that it is a software interface on the computer side of things. It is probably better than using a USB interface into the computer, but not by much. My educated guess is that it will run between 12-15ms of total (roundtrip) latency. That’s acceptable for a single round trip for FOH audio use, but it is too latent to use for monitoring or even for FOH use if you want more than one roundtrip.
Using a hardware Dante device (ie a PCIe Dante card or Dante USB device) to interface into the computer will be better than using a software driver. That would likely bring your round trip latency down to 6-8ms.
I realize this next option is a completely different solution than trying to use the Dante I/O card, but the best/quickest method would be to use a Waves I/O card along with the Waves Soundgrid OS installed on the computer instead of Windows/Mac iOS. The Waves Soundgrid OS and Soundgrid Superrack software has been customized to specifically minimize the system latency. You can “DIY” your own Waves soundgrid computer (by installing the OS - which is freely available on the Waves website - on your own computer hardware), but it does require that you use a valid Soundgrid Superrack license (which normally costs $599) as well as the Waves I/O card. Still DIYing your own Soundgrid computer is far cheaper than buying the premade servers from Waves. The roundtrip latency when using the Waves Soundgrid OS along with the Superrack license is only 1-2ms.
I was the venue tech once for a band that used an old MacBook Pro running… I don’t remember exactly, but they were using whatever plugin host software to run autotune and DVS to connect to Dante.
I wasn’t in on the discussions around their rider, so I don’t know if they’d have preferred a Waves card 
That would probably be LiveProfessor. Highly recommend that if not using WSG natively.
That is what I figured latency wise. I think if I decide to do Waves in that regard, the DIY option would be super helpful and more cost effective. Thanks!
I’ll do some research on Live Professor! I know a couple of a guys that have used it in the past with good results.
