MUIC & ACOUTIC – PIANO & KEYBOARD CALCULATOR
Synthesizer Vco Frequency
A precise tool.
What is the Synthesizer Vco Frequency & How does it work?
The VCO (Voltage Controlled Oscillator) is a core component in synthesizers that generates sound waves based on the control voltage. The frequency of the VCO can be directly controlled by this voltage, allowing for precise tuning and modulation.
In the context of MIDI notes, each note corresponds to a specific frequency. The formula to calculate the frequency from a MIDI note number is given by:
f = 440 times 2^{frac{n-69}{12}}
f = frequency in Hz, n = MIDI note number
Understanding this relationship is crucial for musicians and sound engineers to effectively manipulate the sounds produced by synthesizers.

Frequently Asked Questions
How do I calculate the frequency of a VCO using a MIDI note number?
Use the formula f = 440 * 2^((n-69)/12), where f is the frequency in Hz and n is the MIDI note number.
What is the frequency of middle C (MIDI note 60) on a synthesizer?
Middle C corresponds to a frequency of approximately 261.63 Hz.
How does changing the MIDI note number affect the VCO frequency?
Increasing the MIDI note number raises the VCO frequency, while decreasing it lowers the frequency.
Can you explain how the VCO works in a synthesizer?
The VCO generates sound waves based on control voltage. The frequency of these waves can be precisely tuned and modulated using this voltage.
What is the significance of the number 440 in the formula?
440 represents the frequency of A4 (MIDI note 69), which is the standard reference pitch for tuning musical instruments.
How do I convert a VCO frequency back to a MIDI note number?
Rearrange the formula to solve for n: n = 12 * log2(f/440) + 69, where f is the frequency in Hz.
What is the range of frequencies for standard MIDI notes?
The standard MIDI note range from 0 to 127 covers approximately 8.175 Hz (C-1) to 12543.8596 Hz (G9).
