05 Tape Echo 201
Echo (Tape Echo 201)
This simulates the tape echo part of Roland's RE-201 Space
Echo.
Mode Selector
The RE-201 had three playback heads to make different
delay times (Short, Medium, and Long delay) at once.
Use Modes Selector parameter to set the combination of
playback heads to be used. For example, when you set
"ML," the middle and long heads are selected.
Value Playback heads to be used
S Short
M Middle
L Long
SM Short and Middle
ML Middle and Long
S L Short and Long
SML All heads
Repeat Rate
Value: 0–100
Sets the tape speed. This corresponds to the delay time
in a contemporary delay effect. As the value is
increased, the interval of the delay sounds is shortened.
Intensity
Value: 0–100
Sets the repeat times of the delayed sound. This is
analogous to a contemporary delay's feedback setting.
Raising this value increases the number of repeats.
Echo Volume
Value: 0–100
Sets the volume of the echo sound. Lower it to get a
balance with the direct level.
Bass/Treble
Value: -100–100
These are the echo sound's bass and treble
adjustments. When set to 0, they make no change to the
sound.

Pan Head Short, Pan Head Middle,
Pan Head Long
Value: L63–R63
These are the pan (left–right) settings for each of the
heads for Short, Medium, and Long delay time. This
parameter does not appear on the original RE-201.
Tape Dist.
Value: 0–5
This parameter adds the distortion characteristic of tape.
It reproduces that subtle change in tone that can only be
measured with equipments. The distortion gets more
intense as the value is increased.
Wow/Flutter Rate
Value: 0–100
The wavering becomes more rapid the higher the
Wow/Flutter rate is set.
• The wavering of multiple pitches that appears from tape
wear and irregularities in rotation is called wow and flutter.
(This phenomenon is called "wow" when its occurs at slow
rotation speeds, and "flutter" when the tape is run quickly.)
Wow/Flutter Depth
Value: 0–100
The wavering deepens as the Wow/Flutter depth setting
is increased.
Direct Level
Value: 0–100
Sets the volume of the source sound.
• Since the RE-201 SPACE ECHO has been released in
1974, a great number of fans are still using. This algorithm
faithfully reproduces the sound of the original unit's tape
echo section based on the real unit and the data when it
was developed. What's more, it includes settings to
express the sway caused by the motor, distortion, and
panning for each of the three heads (something the original
lacked). Now, you can easily get this warm, Lo-Fi echo
sound, something different than the clear sound of today's
digital delays. You can change the repeat rate (tape speed)
with the Realtime Effects knobs, and enjoy the realistic
feeling of operating this vintage device.
