Setting the Root Note of a Sample

„ Setting the Root Note of a Sample
With a sample selected in TRIM mode, pressing the [WINDOW] button
will open the SAMPLE page. Here, a sample's Root Note can be edited.
This Root Note parameter selects at what note the sample will play at
true pitch when in a Keygroup Program.

This is a quote from manual
So this means the mpc will detect root note by itselef ?,
or I need to set it?

If it was set already in the sample, the MPC5000 should detect it, otherwise it will default to (from memory) C(60) and you'll have to set it manually.

So I assume that there is no chance for mpc to detect root note of a sample lifted from vinyl??

How I can find... lets say middle c note in synth program sounds????
Is there any way to identify this?
