With SoundManager you are able to control multiple sound channels of one or multiple sound cards. It uses ALSA to speak to the sound cards. An example how to use SoundManager would be a shop or store with multiple rooms where every should have its own speaker. Then with SoundManager you would have a single web interface where you could control every single speaker. SoundManager also allows to create different playlists and assign them to one or multiple sound channels. It is also possible to use line-in or a microphone instead of a playlist.

The SpatGRIS is a plugin (Mac AU/VST and VST Windows format) designed to compose multichannel space. It allows the user to spatialize the sound in 2D (up to 16 speakers) or in 3D (up to 128 speakers) under a dome of speakers (with the ServerGRIS, available here on SourceForge). SpatGRIS is a fusion of two former plugins by the GRIS: OctoGRIS and ZirkOSC with a lot of new features. SpatGRIS has been developed by the Groupe de Recherche en Immersion Spatiale (GRIS) directed by Robert Normandeau and based at the Faculty of Music at Université de Montréal. SpatGRIS and ServerGRIS are still available here but they are not supported anymore. They have been replaced by the duo ControlGRIS/SpatGRIS3 also available at SourceFORGE (August 2021) Have a look at the them: https://sourceforge.net/projects/spatgris3/

Turn your computer keyboard into a chromatic accordion keyboard. Ah, but it already is.. Supports both right and left hand system, currently: - C griff (right hand) - B griff (right hand) - Stradella (left hand standard bass system) Computer keyboard layout must be implemented as a text file in the "keyboard" folder. Currently only italian layout is implemented [UPDATE: added a ISO-fr file in osx release], if you want to implement a layout for your keyboard just read the instruction in the "ISO-it" file (please let me know if it works!). Current version: 1.0 Release notes -> https://sourceforge.net/p/akkeyrdion/blog/
