We are starting up a series of beginners' open source sound and music making, using small, cheap and powerless computers. First we work with some essential software, to move into building your own electro-digital-acoustic environments and instruments, ending up playing together with sound structures from the nature around we like. Paul Demarinis once said "Music is Sound to my Ears". So let's begin with sound, explore it together, and perhaps we will never want to end anywhere else than in beauty. Soon to be announced and documented, discussed and refined here.
