5. Pitch Change
This function is the exact opposite of Time Compression in that it
changes the pitch of a sample without changing the time. The maximum
amount of pitch change is
±
1200 cents (
±
one octave).
1. Activate Digital Processing module.
2. Select Digital Tools II (8), Pitch Change (5). The display will
show the current amount of pitch change in cents
and signal type. (1 cent = 1/100 of a semitone.)
PITCH CHANGE
Tune: + 52cts
Type: mid-2
3. Select the desired pitch change amount. The lower line of the
display changes to show the resulting length of the compressed or
expanded sample.
4. Select the general type of sample to be processed.
The choices are:
deep Predominant deep bass (to 14 Hz)
bass Predominant bass (to 20 Hz)
mid-1 Average source material
mid-2 Average source material (high-mids)
high Source material with high frequencies
tight Maintains time accuracy - Drum loops
broad Low bass energy but critical highs
broad-smooth Both high & low frequencies - Smooth output
difficult Inharmonic or broadband material
noisy Non-pitched - Sound Effects, etc.
tight-smooth Preserves rhythmic accuracy. Use small ratios.
x-smooth Preserves rhythmic accuracy. Use small ratios.
5. If you are not satisfied with the resulting Pitch Change or want
to compare before and after, proceed to Digital Processing, Undo
