Boss PS-5 Owner's Manual page 3

Features
The compact Boss PS-5 pitch shifter is
equipped with a high-performance 24-
bit DSP (digital sound processor) chip,
and features numerous functions with
high-quality sound.
Select from five modes to use - PITCH
SHIFTER, HARMONIST, DETUNE,
T.ARM, and FLUTTER (new effect).
You can get split functions on this one
device, with the Pitch Shifter going into
effect when chords are played, and
Harmonist when playing single notes.
You can even use the Harmonist post-
distortion effects devices. *1
Delay control and stereo outs provide
even more effective detuning.
Effects simulating guitar arming
(T.Arm and Flutter) are included.
With an expression pedal (Roland EV-
5; sold separately) connected, you can
get continuous control of the amount
of pitch shift while you play.
*1 In HARMONIST mode, the instrument's
scale is detected and harmonies are added
to the output. Make sure the instrument is
tuned correctly in this mode. Errors in
tuning will cause the harmonies to be out
of tune as well. In addition, tune the
instrument by setting the reference pitch
A4 to 440 Hz.
Monitor post-distortion volume levels
with the PS-5 after a distortion effects
device in the signal path. Excessive
volume levels can cause the harmony
tuning to slip.
