It's a bit of a wasted opportunity, really. The idea itself is very interesting, left click dragging to hear different sounds. It's just that there's not enough sound variations to make this a reliable synthesizer. Sure, you can layer it and put on effects but it would take up quite a bit of CPU. One of the only things that can make this sound decent-ish is automation with the signal. That's all I need to explain, since there's so little to do with this.
