What is control voltage on a synth?

What is control voltage on a synth?

Control voltage (CV) indicates which note (event) to play: a different voltage for each key pressed; those voltages are typically connected to one or more oscillators, thus producing the different pitches required. Such a method implies that the synthesizer is monophonic.

What is a VCO in synths?

VCOs are used in synthesizers to generate a waveform whose pitch can be adjusted by a voltage determined by a musical keyboard or other input. A voltage-to-frequency converter (VFC) is a special type of VCO designed to be very linear in frequency control over a wide range of input control voltages.

How many volts per octave does a typical analog synthesizer use?

one volt per octave
Frequency and one volt per octave To make the relationship more manageable for synthesizers, an important de facto standard was settled early on—one volt per octave control.

What is control voltage?

Sometimes abbreviated CV, Control Voltage is a DC electrical signal used to manipulate the values of components in analog circuits. Control voltages are used in numerous ways in many different types of electronic circuits for all sorts of purposes.

Can a synth go out of tune?

Analog synths can go out of tune. However digital synths, virtual analogs and wavetable synths etc do not go out of tune.

What is oscillator detune?

Detuning is what happens when you go to transpose an oscillator but stop before you reach a full semitone. It’s a subtle shift in pitch that, when added to another sound, will thicken it in a similar way as two people trying to sing the same note.

What is a VCA in a synth?

It’s the Voltage Controlled Amplifier, or ‘VCA’, and it is an important element in the operation of any analogue synthesizer.

What is the difference between DCO and VCO?

VCO (voltage controlled oscillator) DCO (digitally controlled oscillator): Oscillators that are digitally controlled, but have analog wave shaping. DDS (direct digital synthesizer): Oscillators that are both digitally controlled and produce wave shapes digitally.

What is controlled voltage?

What is 1V Oct?

To be more specific, 1v/oct stands for 1 volt per octave. It is a system that Moog came up with in the early days. One volt corresponds to one musical octave.

What is an analog oscillator (VCO)?

For this example, let’s presume that you have an analog oscillator (or VCO, which stands for “voltage-controlled oscillator”) whose pitch is being determined by the voltage coming from the keyboard. On a 61-note keyboard (five octaves, C to C), the lowest note sends 0 volts and the highest note sends +5 volts.

What is a control voltage and why do you need one?

What makes control voltages so interesting and powerful is that they allow you to experiment with lots of CV sources (the things that send various voltages) going to lots of CV destinations (the things that change based on how much voltage they’re currently getting). Here are some basic examples of CV uses:
