MIDI Frequency Calculator

Calculate the resulting frequency of any MIDI note number using up to six MIDI parameters. This is useful for MIDI musicians as well as audio engineers for recording.

DETAILS

Snapshots 1 and 3 show the extreme ranges; however, only the support of a ±12 semitone range for Master/Channel Coarse Tunings is required by the current General MIDI Level 2 Specification.
Snapshot 2 shows the MIDI Specification defaults as applied to A4 (440Hz).
For practical use, referencing an 88-key keyboard, only MIDI note numbers 21 (A0) to 108 (C6) are useful (where C4 is Middle C). The use of Master/Channel parameters is cumulative, thus supporting twice their ranges when used together. The Fine Tuning parameters allow up to a two-semitone offset from the base tuning reference of A = 440Hz. In all cases, the further use of Pitch Bend Sensitivity and Pitch Bend can extend the playback range by another octave.
