OTOO is a Blast!!!!

Well-Done! "Beep Street" OTOO is a ton of fun! Very well conceived and designed. I just got it so I haven't figured out all the features yet, but its very simple to use, and not complicated. A real joy to use. KUDOS! To the design team! Keep up the good work and THANKS!!! PS: I love the full screen for selecting AUV3 instruments.
