What I really want to do is to be able to select a whole passage that I've played consisting of varying note lengths and just neatly snap all of the ends to the nearest 16th, 8th or whatever I choose. Is this possible?
Thanks! Tom
AJ's suggestion is the right track. The Quantize note length preset is what you need. Unfortunately you can't do both eights and sixteenths in the same pass. You'll need to set it for each.
So, just to point you in the right direction, try this:
1. Choose the quantize note length preset from the Transform Window.
2. Uncheck the hide unused parameters at the bottom.
3. In the upper row, under the Length field, choose "inside" from the drop down menu
4. Set it to, for example . . . 0 ticks in the top filed and a little bit over 240 in the bottom field. Maybe something like . . 1 80. This way all the notes that are approximately a sixteenth note long (240 ticks) will get selected and acted upon.
5. In the bottom row, directly under that length filed, choose quantize from the drop down menu.
6. Set the value to . . . 240 ticks.
7. Press select and operate. That should quantize all your short notes to even sixteenths in length.
8. Reset and repeat for eighth notes. Instead of . . . 240 (or . . 1 . ; which is only one tick longer). You need to use a setting of . . 1 240 (or . . 2 . )
HTH.
