It's a virtual pedals set up with a roland and boss drum machine and two bassline synths, as well as a main mixer. You need to connect the outputs to hear things with virtual patch leads. At the start there is just a basic drum pattern and a bassline going, you can see that both there master outs are going to the mixer. If you drag from the output from say, the drum machine to the flanger or whatever, and the output from that to the mixer, you get that sound. There is a ridiculous amount going on, but you can get some very nice sounds with 10 minutes patience. I particularly like the far left distortion. It can lower the bitrate to give a wonderful lo-fi sound. As for the link, it works fine for me. I'm not sure if it's all boss/roland gear or what, it certainly looks like it and the fonts are spot on.
