Is it my imagination or does it add some latency when you've got the cab module active? I'm running Live 8.

I think it's your imagination... but I'll run a test tonight to see for myself.

I'm still using what ever the first download demo version, and it seems pretty obvious that when I turn off the cab section it goes away... or I could just be hearing less high frequency attack.

I hear it in sonar, but for whatever reason it seems not in reaper/maschine

OK here are my "real latency" test results.
I use Tracktion as a host, I can't imagine getting different results
with different hosts.... but who knows, I never say never.

As expected there is a tinny latency, nothing is "real time", not even hardware but it's so small it's negligible.
Note the time line on the bottom. (in seconds)

Amp only (NO CAB) ----- Latency 0.2 ms




Amp and CAB ----- Latency 0.3 ms




Zoom out ----- Cab creates this "tail"
Could this give you the feeling of latency?




Bottom Line --- NO REAL LATENCY

[hibidy]

I only said what I did because I felt that way in sonar. I'll try it again later but it's a "feel" thing. However, I don't want this "feel" thing to be interprited as an s gear issue, I feel it lies more in sonar (especially having to use the bridge)

Reaper, and the "greatest jam box eva" (maschine) are just stellar with it

Yeah, I'm about 97% sold on it.

Just a note to Mike @ Scuffham. Very nice amp Sim : The best I've come across and I've tried many maybe most all of them out there. I haven't been able to bring myself to buying any of the ( proclaimed ) higher end amp packages yet. Your's is really the only one I've been able to get a good sounding dynamics and proper gain staging to really get a feel for realistic Simulation or modeling. It's next on my list for purchase... really appreciate keeping it a clean interface and keeping the bells and whistles to a minimum. Thanks much for the midi control - I cant' wait to actually use it the way you've laid out the basics. I hope there can be glitch free effects or maybe even a master setting that can bypass resetting the effects and cabs when an amp model is changed. Nicely done I feel that Amp Sims have finally arrived.

Bottom Line --- NO REAL LATENCY

[Edit]

I think I see how you did your test and you're saying that it does indeed add .3ms of latency.

That's very noticeable to me.



[edit] are you sure you're reporting the correct units?

[hibidy]

In my "jams" I've noticed that this seems to feel and react best. But on it's own though it sounds good, doesn't quite have the same "kick" that AT3.5 has.

This just goes to show what I know

Anyways, I'm 99.6% convinced. The only thing nagging at me is that it's x86 only.

You're kidding right? You can honestly perceive latency below .5ms or even 1ms?

A latency of 10 milliseconds or better is the target for audio circuits within professional production structures, local circuits should ideally have a latency of 1 millisecond or better.

We are getting into some serious hair splitting territory here

I hope you are kidding.
But just in case you are not:

1ms is the time it takes sound to travel 1 feet
0.3ms is the time it takes sound to travel 4 inches.

So what you are saying is that if you sit in front of a real amp
and you tilt your head 4 inches back from the speaker... you can feel the latency?

Let's look at it this way:
If you sit 4 inches closer to your monitors
you will offset the 0.3ms latency.
Problem solved!


As for hardware, even $10K studio quality DAC's will have about 1ms delay
each way. (2ms round trip)
Many hardware keyboards/synthies will have latencies of 8ms-16ms, this includes the super expensive ones.

Oh wait, I was reading that as .3 seconds... of course I can't detect .3ms. I don't think the poster of the original test was reporting the correct unit of measure either though.

No, I know all that. I was having a brain fart and reading .3ms as .3 seconds or 30ms... that'll teach me for reading and posting while working.

But... I'm not sure what I'm perceiving then. I get the same effect as when I add something like Vintage Warmer to a project and all of the sudden I feel the latency increase.

I only bring it up because I felt it when I first sparked up S-gear... and later after I had left it along for a bit, I noticed it again right off. You could be right about the cab somehow creating an illusion of extra latency, but I do feel that something's going on.

do you get the same feeling in standalone as well as via a daw?

I've never launched the stand alone.
