What is oscillator modulation?
A modulating oscillator is one that we don’t listen to directly, but instead we use its output to control some feature of the sound we do want to hear. …
What is modulator device?
A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector) is a circuit that performs demodulation, the inverse of modulation. These were the earliest types of modulation, and are used to transmit an audio signal representing sound, in AM and FM radio broadcasting.
What is cross modulation synth?
A common voice architecture for analog synths is to have two VCOs which are both available as audio signal sources, but it is also possible for one VCO to serve as a frequency modulation source for the other. When implemented in this way, the result is often referred to as “cross modulation”.
What does a synth modulator do?
In synthesis, to modulate means to change or control. Here, the control signal generated by one synth component is used to cause a change in another component, and that’s what modulation is all about. Whenever you hear a change in pitch, timbre, amplitude, duration, something is being modulated.
What do LFO’s do?
Low-frequency oscillation (LFO) is an electronic frequency which is usually below 20 Hz and creates a rhythmic pulse or sweep. This pulse or sweep is used to modulate musical equipment such as synthesizers to create audio effects such as vibrato, tremolo and phasing.
Where is modulator used?
RF modulators are used to convert signals from devices such as media players, VCRs and game consoles to a format that can be handled by a device designed to receive a modulated RF input, such as a radio or television receiver.
What are the two types of modulators?
Different Types of Modulation
- Amplitude modulation (AM)
- Frequency modulation (FM)
- Phase modulation (PM)
How does cross modulation work?
An unwanted effect which can occur when two or more (sound) signals present in an amplifier modulate one another, giving additional outputs which are the sum and difference between the signals. In particular, a type of distortion peculiar to variable area optical recording.
What does cross modulation mean?
Cross-modulation is an effect in which amplitude modulation (AM) from a strong undesired signal is transferred to a weaker desired signal. This undesired AM signal is increased in strength until an unwanted AM output 20 dB below the desired signal is produced.
What are the six synth families?

- Paraphonic.
- Polyphonic.
- Number of voices.
- Note priority of synthesizer.
