band-pass filter
a modifier module in the synthesis process which permits frequencies within a specified bandwidth to pass and removes or attenuates frequencies outside this bandwidth.

band-reject filter
a modifier module in the synthesis process which removes or attenuates frequencies within a specified bandwidth and permits frequencies outside this bandwidth to pass unaltered.
Go to Topic: Band-reject Filters
the band of frequencies comprised of all frequencies between a defined upper frequency and a defined lower frequency.

basic synthesizer
a simple configuration of the oscillator, filter and amplifier modules.
Go to Topic: Basic Synthesizers
one of the two values, 0 or 1, that are used in the binary number system.
Go to Topic: MIDI Data
a group of eight bits that forms a value from 0 to 255.
Go to Topic: MIDI Data
1/100th of a semitone.
Go to Topic: Oscillators
in reference to a MIDI sequencer, small, equally spaced time divisions of a quarter note.
Go to Topic: MIDI Sequencer
a synthesis module that combines the audio signals from several or many sources. Often a combiner is given a formal name within a system, and many times the combining function occurs transparently without the user having to include it in the synthesis process. Also called a mixer.

complex waveform
any waveform comprised of multiple frequencies.

computer music
used to refer to any type of music composed with a computer. In some cases the actual sound production arises from the computer itself, and in other cases the computer is functioning as a control unit.

constructive interference
when the amplitude of one wave or frequency combines with the amplitude of one or more waves or frequencies to create an increase in amplitude.

Control change message
a type of three-byte MIDI command that sends information on a specified channel about how a particular musical parameter on the corresponding channel should be changed over the course of time.

control signal
the signal output by a time-variant controller.

cutoff frequency, fc
the specific frequency above which, or below which, (depending on the filter type) frequencies are removed or attenuated.
Go to Topic: Low-pass Filters
a single, complete occurrence of a waveform pattern.
