Hi,
There are many great Foss projects and apps for making music on the Linux platform. To bring people from those different communities a bit closer to each other, there is launched a forum:
http://www.linuxmusicians.com
and a wiki:
http://www.wiki.linuxmusicians.com
The aim is to promote foss audio software and music making on the linux platform by sharing knowledge about working with linux audio apps, songwriting and producing. There is also a possibility to give feedback on your songs or demo's.
You're welcome!
...and keep up your good work with LinuxSampler!
