Re: pitch shifters

It would be nice to have a sub octave plugin much like some of the guitar pedals you get for generating bass notes. :D That is exactly what it is. It would shift one octave up or down (not semitones) and you can detune by 1/4 semitone. Perhaps I misunderstand. Guitarix and MOD are completely separa...

Re: pitch shifters

tramp is sounds sweet.. real time latancy still. even using the compensate option. I'm glade you like it. :D Well, latency compensation means, that the dry signal get delayed by the amount of the latency from the processed signal, to come in sync with the processed signal so that you could use it a...

Re: pitch shifters

The only pitch shifter I've found witch works in realtime is the smbPitchShifter by Stephan M. Bernsee. http://www.dspdimension.com/admin/pitch ... ng-the-ft/ With some small optimization and ported to use fftw3 it work in rt (5.33ms latency), but still use ~50%DSP load. Okay after some more optimi...

Re: Guitarix to VST in Realtime

The connections looking okay. You need to load a soundfont into qsynth, check the configuration button and go to tap soundfont. Load a soundfont with the open button. To check the soundfont, go to channels. There you could see which instrument is loaded to which channel. You could move the instrumen...

Re: Guitarix to VST in Realtime

although my ultimate goal is to play a trumpet sound with my guitar. I would like to send an audio to midi signal (read where LMMS supports this w/gxtuner.lv2). Don't expect to much from gxtuner.lv2 It's midi output is suitable to drive some percussion/drums or produce some (feedback) background st...

Re: Lv2 support in guitarix

Yep, it's a really, really short list,
-non-

Basically we use the same wrapper then the one we use for ladspa, just extended it to read and load LV2 plugs.

Re: Lv2 support in guitarix

I'm glade to hear you like it. :) But I guess you get me wrong here, I talk about to load LV2 plugs into guitarix, not load guitarix as LV2 plug. As guitarix is entirely designed for live usage, that will expand the Effect list enormous. By the way, guitarix comes with record plugs (mono/stereo) its...

trapping-floating-point-exceptions

Recently I've found a nice way to trapping SIGFPE (floating-point-exceptions) when write DSP algorithm. It's fenv.h which is a standard header and provide the function feenableexcept(). Setting it up with feenableexcept(FE_DIVBYZERO | FE_INVALID | FE_OVERFLOW); when running a gdb session, the progra...

Lv2 support in guitarix

Hi

There is now, a very first, experimental, LV2 support in guitarix (git). That means you could load and run mono/stereo LV2 plugs, but no GUI support, only a internal GUI, like the Ladspa ones, will be build by guitarix for them.

greets
just a tramp :D

Re: The first Carla 2.0 beta is here!

At least all those gx plugs which use convolution segfault Carla, the others works, true just with internal UI.
EDIT as well those who use resample segfault carla.
Still all plugs work well in Ardour3 and Qtractor.

EDIT2:
Looks like any multi-threaded plug crashes Carla.

Re: Reviving Beatrix, JACK overhead

Indeed, ideally you would be backing up your claim that JACK adds latency with reproducable measurements, and I would do the same when calling that claim into question. We're both falling short in this respect. I'm willing to stop claiming I'm unconvinced JACK adds latency if you're willing to stop...
