mahlon 7bc47cfc4d Setup espeak TTS. Fix "velocity" -> "gain". 
I was originally thinking the velocity sensor would adjust the midi note velocity.
The downside to this is that you have to wait for a note to play to "feel" the volume change.

When changed to alter the gain of the synth itself, it is much smoother -- works for any
sound, even those that have already started playing.

RPi Theremin

This is a quick-n-dirty Theremin daemon for use on the RaspberryPi.

It is designed to be used with a couple of these distance sensors:

Use 'raspi-config' to configure your default sound output (HDMI, 3.5", etc).

This is intended to be run from daemontools or runit. Quick setup:

# apt install ruby espeak fluidsynth runit
# gem install -Ng
# ln -s /path/to/here/theremin /etc/service
# ln -s /path/to/here/fluidsynth /etc/service
