DAW Octave Conventions (Critical)

The MIDI standard defines note numbers 0-127, but DAWs disagree on how to label octaves. Middle C is always MIDI 60 and always 261.63 Hz, but your DAW might call it C3, C4, or C5. This causes endless confusion when collaborating or following tutorials from different DAWs.

DAWMiddle C labelOctave offset
Ableton LiveC4 = MIDI 60Standard (octave -1 to 9)
FL StudioC5 = MIDI 60Shifted +1 octave
Logic ProC3 = MIDI 60Shifted -1 octave
Pro ToolsC3 = MIDI 60Shifted -1 octave
ReasonC3 = MIDI 60Shifted -1 octave
Cubase / NuendoC3 = MIDI 60Shifted -1 octave

The MIDI note NUMBER (0-127) is always universal. Only the octave label shown in the DAW UI differs.

GM Drum Map (Channel 10)

General MIDI defines a standard drum mapping on MIDI channel 10. Most drum machines, sample packs, and drum VSTs follow this convention. Note: octave labels shown in Ableton notation (MIDI standard). FL Studio users: subtract 1 from the octave number. Logic/Pro Tools users: subtract 1 also.

MIDI to Hz Formula

Hz = 440 x 2^((MIDI - 69) / 12)

This is the equal temperament formula. A4 (MIDI 69) is the reference at 440 Hz. Every 12 MIDI steps = 1 octave = doubling the frequency. Every 1 MIDI step = 1 semitone = a frequency ratio of 2^(1/12) = approximately 1.0595.

Example: MIDI 60 (middle C)
440 x 2^((60-69)/12)
= 440 x 2^(-9/12)
= 261.63 Hz
Example: MIDI 36 (808 root C2)
440 x 2^((36-69)/12)
= 440 x 2^(-33/12)
= 65.41 Hz
Example: MIDI 81 (A5 in Ableton)
440 x 2^((81-69)/12)
= 440 x 2^(12/12)
= 880.00 Hz

Frequently Asked Questions

What MIDI number is middle C?

Middle C is MIDI note 60. Its frequency is 261.63 Hz. Ableton Live calls it C4, FL Studio calls it C5, and Logic Pro / Pro Tools / Cubase call it C3. The MIDI number 60 is always the same regardless of which DAW you use.

What MIDI note is A 440 Hz?

Concert A (440 Hz) is MIDI note 69. Ableton calls it A4, FL Studio calls it A5, Logic calls it A3. This is the international standard tuning reference and the anchor point for the equal temperament frequency formula.

What MIDI note is a kick drum?

In the General MIDI (GM) drum map, the standard kick drum (Bass Drum 1) is MIDI note 36 (C2 in Ableton). MIDI 35 is an alternate bass drum. Most drum machines, Drum Racks in Ableton, and sample packs follow this convention, though custom kits may differ.

How many MIDI notes are there?

There are 128 MIDI notes, numbered 0 through 127. This covers roughly 10.5 octaves, from C-1 (8.18 Hz, below human hearing range) to G9 (12,543.85 Hz). A standard 88-key piano covers MIDI notes 21 (A0) to 108 (C8).

Look Up Any Note or Frequency

Enter any note name (A4, C#3, Bb5) or frequency (440, 261.63, 130.81) to get instant results with MIDI number, enharmonic, cents deviation, and nearest semitone.
