# 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

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.
