Algorithm The combination of a number of Operators is called an “Algorithm.”
When the waveform output from the Operator is a simple sine wave, no
harmonics are included other than the fundamental tone. However, you
can create harmonics by modulating the waveform with other Operators.
How harmonics can be created depends on the Modulators’ output levels
and the frequency rates of Carriers and Modulators. On the other hand, the
basic pitch is determined by Carrier’s frequency, and the output level is
determined by the Carrier’s output level. The figure described below shows
a basic way to create FM sound by using an analog synthesizer.
Figure 2: A basic way to create FM sound by using two operators.
A: Modulator OP: Frequency ratio of the Modulator and the Carrier
determines the base waveform including specific harmonics by the
Oscillator.
B: Modulator output level determines the Cutoff Frequency of the Filter.
C: Modulator envelope determines the Filter envelope.
D: Modulation
E: Carrier OP: Carrier Frequency determines the pitch of the Oscillator.
F: Carrier output level determines the volume by using the amplifier.
G: Carrier envelope determines the amplifier envelope.
Feedback Waveforms can be changed by feeding some of the signal generated by
an operator back through that operator. This is called “Feedback.”
Drum Key A Drum Key is the smallest unit that makes up a Drum Part.
A Drum Key is assigned to individual notes on the Keyboard. The
percussion or drum wave is assigned to a Drum Key.
