We've seen plenty of sites that let you make or mix music in a rudimentary way, but none that offer the deep feature set of Hobnox AudioTool. This free online electronic music studio lets you compose with two TB-303 Bass Line generators, Roland TR-808 and TR-909 drum machines and two banks of effects pedals including three delays, crusher, detune, flanger, reverb, a parametric equalizer and a compressor. By clicking the mouse button, you can drag virtual cables between any output and any input to customize the setup. More →
