Re: Impulse convolver/guitarix
I see in the picture that you have enabled the experimental switch, have you try it without the experimental flag enabled ?
Do you get this behaviour with all presets ?
I mean it's strange anyway, I will start a measure session, to find out what's going on.

Re: Impulse convolver/guitarix
Sure! But I wasn't using the experimental preamp, or does the experimental setting enable an extra stage anyway?
And I'm back on 0.08.0. No lagging.
Here's the relevant preset data:

Re: Impulse convolver/guitarix
So, I have made some measure's with both versions, and couldn't found a diff in terms of time and sample duration, . . ?
I see in the screenshot a jack_buffer_size from 1024 samples, in your preset you use 64 samples, could it be that you run the test with different frames/periode settings then you normal use ?

Re: Impulse convolver/guitarix
Hello brummer, I made the screenshot on a different machine than the machine I normally work on. I'll try compiling 0.09.0 without the experimental stuff and report back.
The setup is like this: sequencer (Hydrogen) with bass sample --> guitarix --> Qtractor
The slight lagging is audible at the beginning of the loop/pattern so it could be a Hydrogen timing issue too. But that doesn't explain why it works with 0.08.0.

Re: Impulse convolver/guitarix
I don't think its Guitarix. You can use jdelay to measure the latency: check out and compile the newest svn version, then switch off all processing (especially tonestack = "Off", jdelay can only work with a clean channel without filtering or distortion) and connect the jdelay ports to input and output of Guitarix (jdelay:out -> guitarix_amp -> guitarix_fx -> jdelay:in). jdelay should report a latency equal to your current jack buffer size.AutoStatic wrote:The fx loop introduces extra latency so now my recorded loops/samples that I run through guitarix are lagging
Switching on oversampling of the amp section (but without any further processing) should add 32 samples latency (that's 0.7ms at a sample rate of 44100).
Off course any filter introduces a phase delay, but I don't think that's what you describe as "lag" (how much lag do you see, in samples?)

does it work when you change -march=K8 to -march=k8 (lowercase k) in trunk/wscript?morko wrote:Hi.

Re: Impulse convolver/guitarix
Hello Andreas, I jumped to the wrong conclusions and already figured out that it's not the FX loop that causes the lagging. It must be something else, I'll reinstall 0.09.0 svn 743 and give it a testride again with jdelay. What about the Experimental part of guitarix, does that introduce an extra stage/latency? Otherwise I should try compiling a version without the experimental switch.adegert wrote:I don't think its Guitarix.

Re: Impulse convolver/guitarix
No it shouldn't, and anyhow there is a switch to activate (or deactivate) it (open the experimental window from the engine menu and check the switches; and maybe just activate it because it sounds good .AutoStatic wrote:I'll reinstall 0.09.0 svn 743 and give it a testride again with jdelay.

For jdelay you'd have to use svn 744, that's the version where I added "Off" to the tonestack.

Re: Impulse convolver/guitarix
Ok, now using svn 746 and all is well, no more lagging and a good sound. Thanks guys!
Re: Impulse convolver/guitarix
Good to hear
AutoStatic, I have move the link for ubuntu karmic binary's , on the guitarix project-page, form pillips to your ppa, hope that is well for you.

Hello brummer, that' s ok!
And I can load presets now with the help of the -f option, was it there before?

Re: Impulse convolver/guitarix
Yes, it's included since 0.08.0, but you cant really load a presetfile with it, you can load a state file, that means a main settings file, guitarix_rc (now guitarix_amp_rc), witch contain a bit more info (GUI settings, . . ) then the presetfiles, so you need to save your preset as "main settings" and rename the resulting file guitarix_amp_rc to your needs to get it permanent. Then you could load it at startup with the -f option.
I have completely forget this option.
