BASIC ARPEGGIATOR ================= This plugin is just what it says. It takes MIDI event input and writes MIDI event output in the form of an arpeggio over the held keys in the input. You can control the speed of the arpeggio and the direction (up or down). CONTROL2MIDI ============ A plugin that converts a LV2 control port value to MIDI CC events. You can set the CC number and the expected range of the input value. KLAVIATUR ========= A MIDI keyboard. You can use it to send pitchbend events, CC events and of course notes, using mouse or keyboard. Handy when you want to test a synth patch but don't have a real keyboard nearby. Klaviatur has a Gtk GUI that you use to control it. MATH-CONSTANTS ============== A set of plugins that output constant control parameters for mathematical constants defined in the C header . MATH-FUNCTIONS ============== A set of plugins wrapping most of the functions in the C header (sin(), cos(), exp(), modf() etc). All are available as both audio rate and control rate functions. PEAK METER ========== A decaying peak meter that shows the peak level of the input signal. There is a mono and a stereo version. Both have Gtk GUIs. RUDOLF 556 ========== A simple drum machine with six separate drum voices - two bass drums, two snares and two hihats. The different voices are mapped to C, D, E, F, G and A in all octaves, and every voice has three control parameters (length, hardness and volume). This plugin has a Gtk GUI that you can use to control the parameters. SINESHAPER ========== An LV2 version of the Sineshaper synth - two sine oscillators fed through two sine waveshapers in series, with a bunch of parameters to control them. This plugin has a Gtk GUI too. THE HOST ======== The host that comes with this package is called Elven (Experimental LV2 Execution ENvironment). It is pretty slow and I don't really recommend it. If you can use another host, do that.
Enfin des greffons LV2 avec les ll-plugins v0.2.0 !

Les greffons LV2 sont une évolution des LADSPA bien connus sous Linux mais péchant par leur trop grand dépouillement. Bien qu'il n'existe que peu d'hôtes pour les utiliser, saluons quand même la première sortie de ces ll-plugins en version 0.2.0. le "ll" venant du nom de l'auteur Lars Luthman. Celui-ci précise: "Ces greffons sont relativement simples et peuvent servir comme exemples ou points de départ pour des hackers qui voudraient écrire des greffons LV2 basés sur les frameworks du paquet lv2-c++tools. Ils y a des synthés, des processeurs d'évènements, des manipulateurs de contrôle et des greffons utilisant des GUI"
En effet la liste complète (cf. la suite) montre surtout des greffons utilitaires pour des fonctions MIDI basiques ou des opérations mathématiques. On notera également une petite b-à-r, un synthé mono, et un hôte simple pour utiliser les greffons LV2. http://ll-plugins.nongnu.org ![]() |
