Overview / Usage

Voice box is a box that's main purpose is to play sounds on another device like a computer or synth module. The box itself doesn't generate any noise on its own at all, if they do it's very limited.
MIDI controllers range from little tiny things that are pretty cheap to make all the way up to massive full sized monsters with weighted keys and gobs of little knobs and sliders for doing cool tricks with your synths.
The point is you already have sounds somewhere else that you want to use and don't want to spend money on something with new sounds that you will never use. You just want something good at sening out MIDI messages. You can order these online or buy them at local music stores. Now-a-days if I was starting out with a goal of only recording music
on my computer (no live playing) I would consider this kind of keyboard.
Thanks to the Intel Edison power and the ability to run nodejs inside we created a box that can record sounds and play them. Have fun to sample your voice and play it or send it in a loop. Use the potentiometers to change the volume and rate.
