Logic Pro 9 Using transformer to randomize only later in time

Had a student ask me today how to use the transformer to randomize note positions. He wanted to randomize only later in time, so the stock preset of +/- doesn't work. I futzed around for a minute or two but had no luck. Any tips? He's using Logic 9.1.7.

Until somebody comes up with a more elegant solution (hopefully), just add a track or region delay equal to the randomise amount.

Thanks Pete, that's an idea. That would advance all notes in the region. I believe randomization doesn't necessarily affect every note, so you'd end up displacing everything, affected and unaffected notes. Not sure that would be a problem, just a thought.

He was able to do this in DP 7, which is why he asked me about it in Logic. Logic is so worthless.....;)

No it includes the actual note. Say you have chosen a position randomness factor of 5, that would include all notes within a range of 5 ticks. That would be from 2 ticks earlier than the note to 2 ticks later 2 + 1 + 2 =5. The notes would be distributed randomly within that field,but that does of course include the note itself. So in this case you would have a delay equal to 2 ticks - then the random notes that were 2 ticks earlier become the "main note" on the beat, and the other notes take up random positions up to 4 ticks later. Hmmm... I think that makes sense.

Just thought I'd jump in here....

Yeah, Pete what you're describing seems like it would work. And kudos on a very thoughtful workaround! The only thing is that the user would have to always mentally divide in half the number of ticks he wants for the randomization range, since the other half will be compensated for by the delay parameter.

So, if he wants to randomize only later in time by up to 10 ticks, he'd have to apply a +/- value of 5 in the Transform window, and then offset by 5 ticks in the region parameter box. So it works, it's just a small extra mental calculation the user should be aware of having to make.

And BTW, this is a very cool feature in DP! :D

Actually, the randomness factor I'm looking at in the transform window is a +/- and does vary either side of the original note placement by that much, not half that much.

So, if +/- 10 is used, you'd need to advance the notes by 10 ticks to ensure all were not played earlier that their original position.

Pete, thanks for the suggestion, I didn't bother to think outside the transform window to work on a solution.

Eli, congrats on your DP 8 series being released!
