Bias: Applied DC voltage and current to active devices (transistors, FETS, op-amps)

DPDT: Double Pole Double Throw

Dynamic range: The difference, in power, of the largest signal and the lowest level signal or noise of a system

Limiting: A circuit is limiting when a signal amplitude is limited (clipped or compressed) at a predetermined power level

MIDI: Musical Interface Digital Instrument. Industry standard for sound-module/keyboard computer I/O (Input/Output) via an interconnect cable

Multitimbral: Multiple instrument sounds being played on different MIDI channels simultaneously from the same synthesizer

SCSI: Small Computer System Interface

Signal-to-Noise: (s/n), the amount of power in a signal compared to the noise of the system
