6. Output Mode
This switches the output format (mono/stereo). This
includes two different stereo settings.
Value Explanation
Mono Output is monaural.
Chorus sound of the pitch vibra-
tion which phase is inverted be-
tween left and right is mixed
St-1(Stereo-1)
with the source sound. This is a
broader chorus, with a weaker
feeling of placement.
The left output contains the
St-2(Stereo-2) source sound, and the right side
has the wavering chorus sound.
This algorithm faithfully reproduces the sound of
the original CE-1 based on the specifications when it
was developed. In Chorus mode (Chorus), you can
get the effect of pitch vibrato chorus added to the
source sound. In Vibrato mode (Vibrato), the
waveform and rate of the wavering of the pitch
differ from those of chorus. (Although later BOSS
vibrato effects do not mix in the source sound, the
CE-1 mixed the source sound when switched to
vibrato as well.) The output mode was added to a
later model, the CE-3. (The sounds of the CE-1 are
reproduced by "Mono" and "St-1.")
