Tuning flute and piano to each other

It really depends. If the flute is equally out of tune across its' range, you could insert a pith shift plugin on the Flute track. If it is only a few cents, sound quality will not suffer audibly.

For EXS instruments, there is a knob in the EXS called "Fine" that is used to fine-tune a given instance of an instrument. I'll bet Ivory has something similar.
Double0click where it says "EXS24" right below "I/O" on the channel strip to see
the EXS window.

In the Project Settings you´ll find the Tab "Tuning". See what happens if you select User and pull up the "Upper" slider to, say, 100%.

Not sure it´ll work but I would be interested to see what happens. Perhaps it will stretch the upper notes of the piano so that they don´t clash with the flute. Or perhaps the flute will follow and the result will be even worse.

Personally, I like the Hermode Tuning system, especially for sounds that are supposed to be "in tune", strings, choirs etc. Pretty tricky to mix with distorted guitars, tough.

If this is a MIDI performance of the flute then:

1) Create new track with identical settings
2) Copy flute performance region from original track to new track
3) Go into original track and use MIDI editor to lasso and delete all notes above the key you want to apply the pitch plug to.
4) Go to new track and lasso/delete all notes BELOW the key you want to apply the pitch plug to
5) Apply pitch plug to new track that has the flute notes in the higher register.

To remove any plug just select the plug "button" and while holding down the mouse you will be given the option to remove the plug.

Hope this is clear.....everything you are asking is pretty simple once you know the "trick".

If you use Pitch Shifter, you can automate the Cents value to
shift more in the higher register, and less (or none) in the lower.

Sort of an aside here, has anybody else found the logic steinway to be about 10 to 12 cents flat of concert pitch, across the keyboard. Is this much the same with most samples in logics library, or is it just every tuner i have checked it with is out?
