Brummer, I was trying to script one of my sessions that includes some Guitarix instances but realized I couldn't specify to load a preset on the command line. Did I overlook something? Or did you already integrate this in a later version (I'm using 0.08.0)?

Thanks,

Jeremy

that was possible once, together with a nogui option, this feature is going lost in space :lol: . . . .

may I could include it back in next time . .

But you can switch/load a preset simply by number (1-9) just send a keyboard event to guitarix :)
or a midi program change message

Ah cool, that'll do. And MIDI, didn't think about it. I'd prefer though loading a preset on the command line though.

Yes, now it compiled. I did modify the wscript file in the lib directory and replaced BINDIR with LIBDIR :)
Thanks brummer!

Wow, it sounds completely different with my old presets, but after some tweaking I have the feeling it all sounds better. Also the JACK port names are changed so I had to update my scripts.

Yes, you need to insert the new options in your old presets, otherwise the new controllers wouldn't recalibrate with a preset-switch. Hope the better sound make it worse.

The Portnames must change, because guitarix is a double client now, guitarix_amp, that's the amplifier with the mono effect chain, guitarix_fx, that's the stereo effect chain and the convolver. You can route Rakarrack in here, or jack_rack, or what ever other effect you need, before it run in the convolver.

The lib dir, in the moment the lib it isn't used, that's the next step on the way to break out the Gui part and make a shared library from it.
And the fx loop introduces extra latency :( That doesn't work for me, all my loops I've recorded are now a bit behind.
Really, that's strange, without connect a hardware port to them ? just guitarix_amp out to guitarix_fx in ?

Hi brummer,

The fx loop introduces extra latency so now my recorded loops/samples that I run through guitarix are lagging :(

Yes, just guitarix_amp out to guitarix_fx in. I'm running samples/loops through guitarix and if I route the sound through the FX chain there's an audible latency. If I don't use the FX chain all is ok, except for the fact that it doesn't pass the convolution engine that way. 0.08.0 didn't show this behaviour.

I think I'll have to rerecord some bass-lines. The bass also lags when I connect guitarix_amp directly to my mixer (Qtractor). So it's not the FX loop, it's probably something else. Weird thing is that with 0.08.0 the bass was spot on.

By disabling the BiQuad Filter and tube in the amp section the latency is smaller. But it still lags a tiny bit compared to 0.08.0. The lag is notably audible at the beginning of a loop/sample.
