lv2-host-minimal

Simple library to host lv2 plugins. Is not meant to support any kind of GUI.

• [x] Host fx plugins (audio in, audio out)
• [x] Set parameters
• [ ] Host midi instrumenst (midi in, audio out)

I could not get midi going. You can see me trying in lib.rs

rust // set up a host with max 1000 plugins and a buffer length of 1 let mut host = Lv2Host::new(1000, 1); // add some plugins host.add_plugin("http://calf.sourceforge.net/plugins/Compressor", "compressor".to_owned(), std::ptr::null_mut()).expect("Lv2hm: could not add plugin"); host.add_plugin("http://calf.sourceforge.net/plugins/Crusher", "crusher".to_owned(), std::ptr::null_mut()).expect("Lv2hm: could not add plugin"); // set a parameter host.set_value("compressor", "Knee", 4.0); // print all ports of first plugin println!("{:?}", host.get_plugin_sheet(0)); // some loop where you get your data loop{ // you have some audio frame let (l, r) = some_way_to_get_your_audio_frame(); // apply the plugins to the frame let (l, r) = host.apply_plugin(0, (l,r)); let (l, r) = host.apply_plugin(1, (l,r)); }
