I made some updates to the example and will make some more. I have some "text" stuff I'm in the middle of working on, but for the sake of moving things along, here's a sample of individual keys.
https://drive.google.com/file/d/0B6hxg-gC2Uz_WXlyeno2YUo4Z00/view I did cheat a little by ignoring how the keys play along with each other, so when you press 3+ keys in the app, the signals collide and clip due to how i did the reverb. This was mostly due to time and contest submission, so i didn't spend much additional time resolving it. It's just lingering on my TODO. I fired up tgui-harm but it seems that I need to get an actual midi device connected before I can make it do anything. I moved recently and have a desk+chair to put together before i unbox my midi keyboard, so maybe I'll try it out then. Suggestions otherwise, I'd say go ahead and let a row on the keyboard play in-place of an actual keyboard.
