I was only dreaming of hardware synths in the early days :)
The first version of Glitch is a freeware multi effect, unfortunately only for Windows I believe and it's 32bit. Glitch 2 is more advanced, compatible with OSX but not freeware. Anyway you can get both from here: http://illformed.org
Thanks @mume ! I downloaded the demo and will buy it if I like it. I'll mess around with it when I get some time. It looks super interesting.
