EDIT SAMPLE
PITCH SHIFT
Pressing PITCH SHIFT will display this screen:
This process is a variation on timestretch. However, the ‘stretch factor’ in PITCH SHIFT is described
in terms of transposition. For example, if you have a sample in the key signature of C which you
want to use during a key transposition of a song where everything is transposed up a tone to the
key of D, set a SEMITONE TUNE value of +02 semitones.
Similarly, if you have a sample that is slightly out of tune, use the FINE TUNE parameter to bring
it back into tune by an appropriate amount.
The AUTO TUNE function allows you to set whether the new sample will automatically be
transposed. For example, let’s imagine you have a set of backing vocals sampled on C3 in the key
of C that you want to transpose so that they can be used during a 2 semitone key change in the
song. With AUTO TUNE set to OFF, after the pitch shift process is complete, if you press C3, the
sound will not be transposed - it will still play in the key of C on the ‘physical’ key C3 only slower. In
order to play the processed sample in the right key in the song, you will have to play D3.
With AUTO TUNE set to ON however, in the same example, after the sound has been processed,
when you play C3, it will automatically play 2 semitones higher in the key of D.
You may prefer that after processing the sample, it automatically transposes to the new pitch.
However, it could be that you find it odd playing the note C3 when the song is now in the key of D
so you may prefer to leave AUTO TUNE off and actually play the note D3 to hear it at the correct
pitch and speed.
As with the TIMESTRETCH page, a series of presets optimised for certain sounds is provided.
The ADJUST parameter is available via the PRESET parameter’s WINDOW function.
Pressing RETUNE SAMPLE will initiate the pitch shift. You will see the usual “Processing sample”
progress display followed by the PLAY/KEEP ORIGINAL/NEW/BOTH and RENAME prompt.
Respond accordingly.
NOTE: It is not possible to retune just a portion of the sample.
NOTE: When pitch shifting a sample that has loops, you may find that the processed version’s
loop points are slightly disrupted and exhibit clicks. To overcome this, visit the LOOP page and
try AUTO FIND and/or a CROSSFADE - this should restore the loop farily easily. However, a
bit of work may be necessary to get a perfect loop again.
