Logic 9 piano roll: spacing note equally

    Hi, I have a bunch of notes in the piano roll editor.
    I would like to space them equally.
    (like using a mathematical function...)

    How would you guys do that?

    Help appreciated.:brkwl:

    That's really going to depend on how they're spaced now. Are they anywhere close to the tempo grid? If not, you may have to SMPTE-Lock them and change the tempo until they line up as closely as possible with the grid, after which you can unlock them again and Quantize them. (Sometimes this requires manually moving some blocks of notes that Logic interpreted as, for example, a quarter-note 'early' back to where they need to go) Once you've got them quantized to equal 'spacing' you can alter the tempo to whatever it needs to be.

    Thanks for you answer.
    Quantizing does not solve my problem though.
    I was looking for a function that would horizontally evenly space the selected notes in the piano roll editor, using the left most and right most notes as boundaries.
    That's because I recorded a free piece, without a tempo, so I cannot use the grid as a positionning tool (like in other cases where notes are being positionned on the grid right from the beginning).

    Anyway, I suppose that this function does not exist yet, so I will do that work manually.

    Maybe I have misunderstood, but I think my strategy will still work, or at least save you a lot of time manually repositioning notes. First select-all and move the first note to 1 1 1 1. Then exit piano roll back to the Arrange page and make sure the region is selected. Select Lock SMPTE Position (Command-L, or select in the Region menu) and go back into Piano Roll view. Now drag the tempo up and down a bit, releasing between changes until the tempo grid visually aligns more-or-less to the piece you've played. If there are parts that are dramatically out of whack, you may need to break your original performance into pieces, but you'll see where you have to do this at this point. Once you're more or less lined up with at least a piece of the original performance, you can select the part that's somewhat lined up and quantize just that. (You'll have to Unlock first - Command-U) Now put the Lock back on and keep tweaking the tempo until the next bit is lined up, and so on.

    Well, thanks again for your time.
    I'm sure your workaround works fine, and may help future readers.
    My case scenario is possibly be much simpler that what you might expect: here it is:


    In this image, there are three notes selected, I was just curious about a "simple" way to align those three notes horizontally.
    I have to admit that I find your solution very complex, although I'm grateful for it.

    Oh, goodness me, I've given you the Calculus equation to solve 1+1 haven't I? If you really want to align them, just hold Shift-Option while you drag their position in the numerical display, but I suspect you want to do something more like averaging them, in which case I guess you should just move them manually.

    Actually, the goal was to fix some imperfections (and there are a lot...) that I did while recording the piece through a keyboard via midi.
    I hoped that by applying a mathematical function I would have a perfect triplet for instance instead of a "sort of triplet".
    Triplet was the simplest example, but I have more complex similar examples where such a function would have been useful.
    Don't worry, I have noticed that audio software (I use finale too),
    altough very capable and powerful, are generally less gui intuitive than a photoshop for instance. It seems that some basic features are simply missing (I would argue). So I am kind of used to it.
    I should probably make suggestions (and complaints) to the logic audio team...

    Can't you just select those three notes in the Piano Roll Editor and use the Quantize tool to quantize them to triplets? If they stack as a chord as a result, just hit Undo, spread them out a bit more before re-selecting, and then try quantizing them again to triplets.

    That's what I ended with.
