ALSA MIDI Kommander is a DCOP interface exposing many ALSA Sequencer features for shell scripts, Kommander scripts, or KDE programs requiring MIDI sequencer services. A few utilities are included, which can be used both as programming examples and as real work tools. The main program, "kaseq" is a single executable used as a DCOP service program. It runs as a daemon, allowing only a single running instance, and provides a system tray icon to give visual feedback for MIDI activity and a way to control the program's execution.
The Advanced Linux Sound Architecture is composed of several parts. The first is a fully modularized sound driver which supports module autoloading, devfs, isapnp autoconfiguration, and gives complete access to analog audio, digital audio, control, mixer, synthesizer, DSP, MIDI, and timer components of audio hardware. It also includes a fully-featured kernel-level sequencer, a full compatibility layer for OSS/Free applications, an object-oriented C library which covers and enhances the ALSA kernel driver functionality for applications (client/server, plugins, PCM sharing/multiplexing, PCM metering, etc.), an interactive configuration program for the driver, and some simple utilities for basic management.
AMIDI-Plug is a MIDI subsystem for XMMS, BMP, and Audacious. It processes MIDI files and sends their events to one of the available backends (currently ALSA, FluidSynth, dummy). With the ALSA backend, any hardware or software synthesizer, as long as it provides ALSA sequence ports, can be used to play MIDI with AMIDI-Plug. With the FluidSynth backend, AMIDI-Plug directly accesses the FluidSynth library for MIDI playback and sends the generated audio into effect and output plugins of the player. A dummy backend is also provided for testing and analysis purposes. Playback is fully functional: play, stop, seek, pause, song information are available.
AVChat is audio and video chat software based on Flash Communication Server with an easy to use interface. It supports real time audio/video communication with bandwidth control and automatic webcam and microphone detection, enhanced text chat with a language filter and bold/italic/color options, a users list with genre/camera/admin icons, private and public rooms, an admin section with log review and ban/kick by IP, a nick filter, and support for free and premium users. A PHP file is used for configuration options. Flash Communication Server is used for the text/audio/video streams.
AZR3-JACK is a port of the free VST plugin AZR-3. It is a tonewheel organ with drawbars, distortion and rotating speakers. The original was written by Rumpelrausch Täips. The organ has three sections, two polyphonic with 9 drawbars each and one monophonic bass section with 5 drawbars. The two polyphonic sections respond to events on MIDI channel 1 and 2, and an optional keyboard split function makes the bass section listen to the lower keys on channel 1. The three sections have separate sustain and percussion switches as well as separate volume controls, and the two polyphonic sections have separate vibrato settings. All three sections are mixed and sent through the distortion effect and the rotating speakers simulator, where the modulation wheel can be used to switch between fast and slow rotation, and the fast and slow rotation speeds themselves can be changed separately for the lower and upper frequencies.
