I finally bought the Dimehead NAM Player

[Bevo]

I did, I assume you mean this one where all the tests are from 3 years ago.

QC numbers report (latency, send levels, etc.)

Here is what I measured : [Screenshot 2023-03-08 at 13.32.27] From here we can say that Row 3 adds latency (2.67ms) if used with blocks FXLoops add latency (1,85ms) due to the Analog to digital conversion when using the Return. An FXLoop on Row 3 is the latency super-bundle (7.19ms) These measurements are done with either a Gain Block OR an FXLoop Block, not both at the same time and with no other Block on the chain.

So from what I gathered, the fx loop on row 1 adds 1.75ms, close to what Leo Gibson reported (2ms). So if you’re just using the first row for your NAM fx loop, it’s fine, the loop + the Dimehead would add <3ms.

But there is a bug (or was, I can’t tell) where row 3/4 adds several ms latency, and is magnified further by adding an fx loop there.

Can’t tell if Neural ever fixed that. Maybe not, although they did do an update where latency was improved, but it’s not clear if they ever fixed the row3 - fx loop latency mess.

So cheers for the headsup, I won’t be using the fx loop on row 3/4 in the future. But row 1 seems safe.
