Well. What could be cool was to provide some raw clips that can later be 'reamped' be people to show off their effects.
Raw synths, vocals, guitars, basses etc etc. Then clips would be comparable so that the effect can be in focus, and not the playing.
This could be organized on a simple website for downloading the raw clips and uploading the samples with applied effects and a link to the code and schematic for instance.
I have a fetish for these 'one service' sites, and as a fellow musician I'd love to participate on an effort like this!
Feel free to contact me directly if you want to start a dialog.
The simple alternative is to open an account on myspace soundclick etc and either keep the login to yourself, or share it with interested contributors.
