4.6 MIDI Note Naming Reference
MIDI notes are numbers between 0 and 127, while music notes are lettered A through G# (in traditional
Western notation) —!there must be a way to convert between the two. There are actually multiple
standards for naming MIDI note numbers, which can make things tricky.
KMI follows the C3=60 standard for naming/numbering notes. Below is a chart that can help with
converting note numbers to note names and vice versa.
Note: Other software/hardware may follow the C4=60 naming scheme (or even C5=60), which can lead to
some confusion when MIDI mapping or setting up 12 Step. All MIDI notes will appear to be an octave off (by
name), but in MIDI-land they have the same note number —!which is all that matters.
