This is just a sketch I did tonight with a free VST plugin called Transition that randomizes your synth sound, according to presets or to your own design.
I have tried demos of the big VSTs that collectively you could pay a small fortune for. My most fun comes from creating my own sounds by combining free VSTs. In this case, it’s Firebird and Transition.
