The concept is super cool. The execution was done pretty well. After adjusting to the controls, I was able to hook things up pretty quickly and try out different things. I think I was pretty close to the end, but the three low pass filter level stumped me. Partially this was due to the fact that once I reached a certain "closeness" to the final wave, it just felt like a lot of guesswork and trying out all the combinations (and I understand how these things work!). I think there is a little bit of a disconnect between seeing a wave's visualization (or even hearing it) and being able to identify the oscillators/gates/filters used not to mention the order to use them. There *might* be a way to slowly build up the skill set to do this, but I think it would take a lot more carefully thought out intermediate levels. Anyways, mad props with this. I've never seen anything like it and thoroughly enjoyed my time.
