Free Browser based 303!
For the knob twiddlers amongst you - This is a free browser version of a Roland 303. That might not mean much to you but it's an instrument I can guarantee you have heard. For those interested it was introduced in the early 80's as a cheap way for musicians to have bass lines to play along with. They bombed in the shops until producers of dance music started picking them up cheaply and abusing them in the studio - It's the sound of raving in a silver box and it's a free link. :)
open the link hit play, then randomise and start fiddling with the resonance and cut off - have fun :) :) :) Aciiiiiiiid!
