Logic 9 Must ask as I am stuck

    I am sorry to bother you all again, but I am stuck with a Piano Roll problem I cannot resolve. I have a piece in 3/4, and on each quarter note it needs 6 16th's. When written in the score it looks fine, but I know that isn't where the music comes from,in the Piano Roll the there is no room for 3 sets of 6 16th's in each bar. I have tried many ways to get this done,including that old Logic Pro Help file that is supposed to add equal lengths for all note lengths via the drop down Transform menu,it did turn the first 2 beats into what I need but it doesn't sound right on playback. The midi note objects overlap and are never shown in a way that produces the effect one see's in the score. In the event list they have a value of 0!?! Also in the yellow help box. If they were to overlap in a way that sounds like 6 16th's that might work, as the end of each would fall under the next 16th. Is there not a better way? I don't seem able to find the right combination of quantize value and n-tuplet values to get this done.

    can you explain what you mean by "where the music comes from". The music comes from the score just as much as the piano roll. Though as we know, pedantically speaking, the actual music is not MIDI information, or even the digital waveform, but the sound coming out of our speakers.

    I think if you want semiquaver triplets, the best way to write them (given that you understand notation, is in the score. Or maybe I'm misunderstanding the question.

    In the piano roll, for any notes too long or short, assuming you want legato, I would use note force legato.

    Hi Pete, thanks for the reply. Where the music comes from refers to the fact that things may look right in the score but the actual sounds[music] are determined by what is in the MIDI matrix[sorry-Piano Roll].
    The triplets look great in the score but don't sound the way they look,so I must make changes in the Piano Roll to get the sounds I see in the score. This allways makes the score look unusually complicated, but that's the way it works as taught to me by you and Colin and Eli,etc.
    I am not using legato,the notes are played by the strings and they are so fast that the idea of their being legato is not any help,but many thanks for trying.

    I still don't quite understand.

    If I write semiquaver triplets in the score that is how they look and sound (given a 16/24 display quantise). And if I choose 1 1/24 grid, they appear correct and on the grid in the piano roll.

    I understand that if you played them in unquantised, they may appear as semiquaver triplets if accurate enough, and could be quantised to 1/24 .

    Thanks Pete, considering how much you have already done for me I am very appreciative of your taking the trouble to do this again. I must remind you that I mouse input only[unless it's a wind solo then EWI]
    I will try to upload some examples to make it more clear. I uploaded 2 screenshots-piano roll and score, plus a zip mp4 of the violin playing the piano roll. If these were uploaded you should be able to hear that the violin is OK in the first 2 quarters but the 16th's,which should all be the same length and velocity, are not what they should be when played back. I had divided 3840 by 24 and got a 16th length of 160,but I am old and sick so I forgot the piece is in 3/4 so I will do the math again tomorrow and see if this can be fixed like that via the event list.

    Pete, You must be a great teacher, you let me find the answer myself instead of jumping in to show off your superior knowledge,thanks for that lesson. Re doing the math reduced the 16th size from70 to 40, after that all is going well, lots of copy/ paste,but getting the work done properly now.

    haha, you're welcome

    One thing puzzles me about your example, you have entered the notes not as 1/16 triplets, but as n-tuplets.

    I would think it is better to use the triplet value, as it's already there as a default i the partbox. There is no real need to show the denominator (6:4) as any musician who can read music would know how to play a 1/16 triplet, and that six fit into the duration of four.

    Yes Pete, I am an idiot, as I was finishing the last sextuplets in the cello part I saw the triplet option and kicked myself for having messed up something so simple, I blame it on the strong benzodiazepam pain medication, but I have too much pain without them to walk more than 380 meters. I still think you are a good teacher because you didn't suggest the obvious and forced me to see it later, oh well, the music is nice. And playing arias originally for a castrato singer on a WIVI soprano sax is great fun!

    I am having an issue with MIDI notes having sudden unplanned velocity changes, have you heard of this before in Log accompanimentic?

    About those triplets, no musicians will be hurt in recording this, the sequencer plays the string accompaniment.
