Delay (Virtual Analog Delay)
This effect simulates the compact analog delays used for
guitars in the 1980s. This imparts the analog delay’s
characteristic mood, giving you that soft, velvety sound.
Repeat Rate
Value: 0–100
This corresponds to the delay time in a current delay
effects unit. The higher the value selected, the shorter
the interval of the delay sound.
Echo Level
Value: 0–100
Sets the volume of the delay sound.
Intensity
Value: 0–100
Sets the repeat time of the delayed sound. This is
analogous to a current delay effect’s feedback setting.
Raising this value increases the number of repeats.
Direct Level
Value: 0–100
Sets the volume of the source sound.
• This reproduces such parameters as the frequency
response of the BOSS compact analog echo in the middle
80’s. As it simulates the limitation of the performance of
“BBD (analog IC)” as well, delay times are shorter than with
other delay effects. Although the actual unit had no direct
level setting, it is included in this algorithm in the interests
of convenience.
Chorus (Virtual Analog Chorus)
This algorithm reproduces the sound of the BOSS CE-1
Chorus Ensemble. It adds a vibrating effect and breadth to
the source sound.
Mode (CE Mode)
Value: Chorus, Vibrato
This switches the sound between chorus and vibrato
modes.
• 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.)
Chorus Intensity
Value: 0–100
When CE Mode is Chorus, this sets the pitch vibrato
speed.
Vibrato Depth
Value: 0–100
When CE Mode is Vibrato, this sets the pitch vibrato
depth.
Vibrato Rate
Value: 0–100
When CE Mode is Vibrato, this sets the pitch vibrato
speed.
Direct Out
Value: Off, On
This switch determines whether or not the source sound
(although monaural) is mixed in. On the original CE-1
this was fixed at On.
