Everyone's favorite SynthTuber (sorry Bad Gear guy) gets played by his own device (and the Beetlecrab Tempera). With explanation! I figured subjecting everyone to talking was warranted for this one.
Anyone who doesn't know Tempera, I forgot to explain that the white LED down bottom is a "key" being held on the on-screen keyboard. You need both a placed emitter, and note information to have Tempera make sound. It's just holding the note that plays the "hi"s at their base frequency.
I also forgot to mention that I chopped out the "hi"s separately using Audacity before I used Csound to compile the tracks. Csound could also have done that, but it would require writing down a lot of numbers and plonking them all in. It's faster to just highlight a "hi" and hit "export selection" 64 times, then compile those.
The once you don't hear a "hi" when I placed an emitter is, I believe, because I let it go too quickly. I could work that out in the Csound script if I felt like spending more time on this. Haha!
