There is a large number of open-source software tools for working with audio. From low level programming tools to full-fledged digital audio workstations. On another side, there are musicians, producers and sound designers who use many hardware tools and there are few open-hardware alternatives for musical applications.
Audio designers, musicians and producers don't usually have software development skills and need graphic tools for audio processing. Many of them want to take their algorythms to stage or to the studio "in a box".
This is a small step towards the possible development of an open and portable audio processing platform.
