MIDI is a serial connection between devices. 8 bit words.
One cable 16 channels - each device or voice of a device listens to one channel and only responds to or sends information on that channel
Some devices have more than one voice which means that they can play more than one sound or bank of sounds at a time.

Types of synthesis
additive - adding together different waveforms in order to synthesize more complex waveforms. Uses the Fourier theory that all complex waveforms are made up of sine waves. Therefore by adding together all the right sine waves and complex wave may be synthesized.

Granular synthesis
(adaptive) - changing existing sound samples (wave table)
