There's plenty of different midi file formats. I'm imagining a program that can go into a midi file, find some moment where, say, the notes C4, E4, and G4 (midi numbers 60,64,67) are sounding simultaneously, and change the midi file so that sound of the E4 for that moment is lowered by 13.686¢, and the sound of the G4 is raised by 1.955¢ (frequency of note number 64 lowered from 329.627557 Hz to 327.031957 Hz, frequency of note number 67 raised from 391.995436 Hz to 392.438348 Hz) in order to create a justly tuned major triad.Īre midi files formatted in such a way that you could open them as a plain text file, find a moment like the one I specified, and make the desired alteration to the file so that the sound is altered upon importing the midi file for playback? How would I go into that midi file and adjust the pitch associated with specific note or notes up or down by a certain number of cents? Or does midi work in raw frequencies rather than cents? Either one would work.
#Midi note number to pitch software#
Say I export a score that I'm writing with music notation software as a midi file (or I suppose any midi file, but that's where my midi files will come from). Or you could do it earlier in the process, with the Time Quantize section next to the Flex Pitch editor. You can do this by viewing the generated MIDI region in the Editor panel, selecting all of the notes, and choosing a beat size in Time Quantize at the left. You will probably want to quantize your notes too, which makes notes start on the beat.
This will generate a MIDI region with the notes Logic can detect from your audio.
Right-click the audio area and choose “Set all to Perfect Pitch”įrom the Edit menu of the Editor area, choose “Create MIDI Track from Flex Pitch Data”, at the bottom
Confirm “Turn on Flex”.Ĭhange the Flex pop-up menu at the top of the Editor from “Flex Time – Automatic (Slicing)” to “Flex Pitch” You will be asked ‘Do you want to turn on Flex for track “Audio 1”?’.

Here’s how to do it in Logic Pro X (where it’s different from earlier versions):ĭouble-click the clip to view it in the Editor panelĬlick the Show/Hide flex button near the top left of the editor window, to the right of the menus
