Logic Pro 9 Score question

Is it possible to detach the score notation notes from the the actual recording in the arrange and piano Roll?

What I mean is that I recorded a piano performance using the pedal. The goal was originally a for an album, but now I want to extract the music parts.

However, the score writes a 1/4 note when I want it to write a 1/2 note. Now I know that I can extend that note in the piano roll, but I don't want to change my recorded performance, I just want the score to write it in a musical way.

Is there a solution for that or should I deduct that I should always create a different session when it's time to extract parts from a recorded session?

It strikes me that if you played a 1/4 note with sustain pedal and now you want it to score as a 1/2 note you won't appreciably change the performance by changing the note in the piano roll, as the software is already doing that with the sustain pedal. That said, when I have run into the same issue in the past, I've usually made a silent (muted) copy of the performance track and used it to make my score edits in. That way I keep the correct score within the same song file. HTH

Yeah, I'll do that on the copy.

Doing it on the original would probably not change much, but I just don't like the idea of changing my original performance.

Also I wonder what hapoens when your sustain is the gradual continuous controller. That could modify the performance I think, but probably not much.

I think Doug's answer is exactly what you want, and it won't change the performance. It lenegthens notes to their actual sounding length (with the sustain) and removes the sustain info. It makes the piano roll (which doesn't display sustain) look correct re: note lengths.

It won't necessarily make your score look correct depending on overlapping notes, but it does make editing easier and it would make some aspects of the score look correct. there is always some editing to be done when you want to generate sheet music from a performance.

Also I wonder what hapoens when your sustain is the gradual continuous controller. That could modify the performance I think, but probably not much.
Sustian is not gradual, it's either on or off (0- 63 =on, 64 - 127 = off, or is it vice versa?)

Pete,

I'm pretty sure that if you have a continuous controller sustain pedal, the sustain will be of various length depending on where it was when you hit the note. It is not just an on/off switch.

When we use "Sustain Pedal to note length", it will extend the note until CC64 reaches 0, but when we use Half Pedal, sustain does not necessarily wait until that point before it goes off.

Also, Ivory Piano (and other piano samplers I presume) can release some pedal noise when pedal is released. That would obviously be lost with "Sustain Pedal to note length".

Granted, it would not change much and could go unnoticed, but there is a difference.

I don't know about Ivory, but I use EXS24, and trigger pedal noise as a release sample with note off. I'm sure something similar must be possible with piano VIs.
