Perfomance, Midi and effects
Hello, I'm looking for some simple effects, something equivalent to the Calf pulsator and a lowpass filter with resonance, which I can control with MIDI cc. I'm not wanting to run a DAW because the machine it's on is rather underpowered. I feel like I'm missing something obvious here. Can you help?

Re: Perfomance, Midi and effects
jalv lets all the LV2 plugins run like a standalone, and the rakarrack effects
were recently ported as individuals (!), guitarix provides many lv2, and there are
invada, calf, and mda collections, along with a ton of individual plugins,
and many smaller plugin collections. A veritable candy store...
command lv2ls
and a list of all your installed LV2's will appear, copy/paste an mrl to jalv.gtk,
a command would look like
jalv.gtk http://drobilla.net/plugins/mdala/RezFilter
jalv.gtk http://calf.sourceforge.net/plugins/Pulsator
(note that internet connection is not used in any of this procedure)
Then connect things with your patchbay.
Cheers

Re: Perfomance, Midi and effects
You'll probably need some kind of plug-host, (Calfjackhost, Ardour, Carla, Qtractor, Muse etc) then load the plugin and assign CC to it. I don't think that too many fx plugs have built-in midi control but I could be mistaken.

Re: Perfomance, Midi and effects
i don't think jalv passes midi CCs through except for plugins that support automation built-in like the calf set, but you might as well just use calfjackhost if you're only using calf pluginsglowrak guy wrote:jalv lets all the LV2 plugins run like a standalone, and the rakarrack effects

Re: Perfomance, Midi and effects
Calfjackhost has no midi input unless the plugin is midi enabled, such as calf rotary speaker. Jalv doesn't obviously either. So they're no good.
Re: Perfomance, Midi and effects
as I said before carla should work, but i also just tested calfjackhost from the kstudio calf-plugins-git (which should be up-to-date) and it seems to support midi CCs for both the pulsator and filter.Baggypants wrote:Calfjackhost has no midi input unless the plugin is midi enabled, such as calf rotary speaker.

Re: Perfomance, Midi and effects
I've not tested Carla as I can't find useful packages for Fedora. (Which I'm using to make my life difficult, it seems) I have found midimsg https://github.com/blablack/midimsg-lv2 which might be helpful if I can figure out how it works. and I've packaged here https://copr.fedoraproject.org/coprs/ba ... s/monitor/
I'll also look at building a new package based on calf-git.

Re: Perfomance, Midi and effects
I don't think midimsg will do what you want, it has to do with the manipulation of midi messages into other midi messages. controlling plugin parameters is the job of a plugin host like calfjackhost or carla. as the midimsg README file notes, you could use ingen as well, which is also a plugin host.Baggypants wrote:I have found midimsg https://github.com/blablack/midimsg-lv2 which might be helpful if I can figure out how it works.

Re: Perfomance, Midi and effects
I managed to get Carla kind of running on Fedora, what a monumental faff that was, lots of hard coding of /usr/lib when Fedora wants things in /usr/lib64 and it's pretty crashy at the moment for some reason. Anyway it works.I'll post the rpm later, unfortunately there's no way I'll be able to put it on copr because it bundles the VST libs.

x86_64 rpms here http://therobinsonfamily.net/repo/23/x86_64/
srpms here http://therobinsonfamily.net/SRPMS/
It's a fairly shonky build, I mainly focused on getting lv2 support. Fluidsynth and linuxsampler wasn't included. Other plugins types not tested.

Isn't /usr/lib a symlink to /usr/lib64 on your system?Baggypants wrote:lots of hard coding of /usr/lib when Fedora wants things in /usr/lib64

not at all, nor in opensuse (which is my distro).sysrqer wrote:Isn't /usr/lib a symlink to /usr/lib64 on your system?Baggypants wrote:lots of hard coding of /usr/lib when Fedora wants things in /usr/lib64
afaict, on 64bit systems, /usr/lib64 is the place for ELF 64bit system libraries, while /usr/lib is the resort for ELF 32bit ones OR for architecture independent modules OR those that are mixed architecture (32 and 64bit).
other distros, other than the ones mentioned, opted for no dual or multi-arch support, so you'll most probably find that /usr/lib64 is a plain symlink to /usr/lib on exclusive 64bit systems (on 32bit systems there's no /usr/lib64 to start with).
hth.

The nice man at KXStudio is looking into it though. https://github.com/falkTX/Carla/issues/289
