Tell us about yourself!
Made it, works great (except at loud volumes). I used a TL072 instead of a TL071, and hooked its 2 amps in parallel, which helped to prevent distortion, and I added a 47uf capacitor to the output, in parallel with the 10uf, which gave it a nice boost in bass
You didn't install the minim library. Minim comes included by default on Processing 2 but not Processing 3.To install it on processing 3, click sketch > import library > add library, then search for minim and click install.Hope this helps
