Roland FP-4 Midi Implementation

MIDI Implementation
●0159: Tape Echo
A virtual tape echo that produces a realistic tape delay sound. This simulates the tape echo
section of a Roland RE-201 Space Echo.
●015a: Reverse Delay
This is a reverse delay that adds a reversed and delayed sound to the input sound. A tap
delay is connected immediately after the reverse delay.
●0172: Lo-Fi
This is an effect that intentionally degrades the sound quality for creative purposes.
●0175: Telephone
●0156: Gate Reverb
This is a special type of reverb in which the reverberant sound is cut off before its natural
length.
No Parameter Value Description
1 Mode 0 - 6 S, M, L, S+M,
S+L, M+L,
S+M+L
Combination of playback heads to
use
Select from three different heads
with different delay times.
S: short
M: middle
L: long
2 Repeat Rate #1 0 - 127 0-127 Tape speed
Increasing this value will shorten the
spacing of the delayed sounds.
3 Intensity 0 - 127 0-127 Amount of delay repeats
4 Bass 0 - 30 -15- +15 dB Boost/cut for the lower range of the
echo sound
5 Treble 0 - 30 -15- +15 dB Boost/cut for the upper range of the
echo sound
6 Head S Pan 0 - 127 L64-63R Independent panning for the short,
middle, and long playback heads
7 Head M Pan 0 - 127
8 Head L Pan 0 - 127
9 Tape Distortion 0 - 5 0-5 Amount of tape-dependent
distortion to be added
This simulates the slight tonal
changes that can be detected by
signal-analysis equipment.
Increasing this value will increase the
distortion.
10 Wow/Flutter
Rate
0 - 127 0-127 Speed of wow/flutter (complex
variation in pitch caused by tape
wear and rotational irregularity)
11 Wow/Flutter
Depth
0 - 127 0-127 Depth of wow/flutter
12 Echo Level #2 0 - 127 0-127 Volume of the echo sound
13 Direct Level 0 - 127 0-127 Volume of the original sound
14 Level 0 - 127 0-127 Output level
No Parameter Value Description
1 Threshold 0 - 127 0-127 Volume at which the reverse delay
will begin to be applied
2 Rev Delay
Mode
0 - 1 ms, note When this is set to “note,” the effect is
synchronized with the tempo.
3 Rev Delay Time
#1
0 - 127 1-1270 ms Delay time from when sound is input
into the reverse delay until the delay
sound is heard (Hz)
4 Rev Delay Time 0 - 21 note Delay time from when sound is input
into the reverse delay until the delay
sound is heard (note)
5 Rev Delay
Feedback
49 - 89 0- +80 % Proportion of the delay sound that is
to be returned to the input of the
reverse delay
6 Rev Delay HF
Damp
0 - 17 200-8000 Hz,
Bypass
Frequency at which the high-
frequency content of the reverse-
delayed sound will be cut (Bypass:
no cut)
7 Rev Delay Pan 0 - 127 L64-63R Panning of the reverse delay sound
8 Rev Delay
Level
0 - 127 0-127 Volume of the reverse delay sound
9 Low Gain 0 - 30 -15- +15 dB Amount of boost/cut for the low-
frequency range
10 High Gain 0 - 30 -15- +15 dB Amount of boost/cut for the high-
frequency range
11 Balance #2 0 - 100 D100:0W-
D0:100W
Volume balance of the original sound
(D) and the delay sound (W)
12 Level 0 - 127 0-127 Output volume
No Parameter Value Description
1 Pre Filter Type 0 - 5 1-6 Selects the type of filter applied to the
sound before it passes through the
Lo-Fi effect.
2 LoFi Type #1 0 - 8 1-9 Degrades the sound quality. The
sound quality grows poorer as this
value is increased.
3 Post Filter Type 0 - 2 Off, Lpf, Hpf Type of filter
Off: no filter is used
Lpf: cuts the frequency range above
the Cutoff
Hpf: cuts the frequency range below
the Cutoff
4 Post Filter
Cutoff
0 - 16 200-8000 Hz Basic frequency of the Post Filter
5 Low Gain 0 - 30 -15- +15 dB Gain of the low range
6 High Gain 0 - 30 -15- +15 dB Gain of the high range
7 Balance #2 0 - 100 D100:0W-
D0:100W
Volume balance between the direct
sound (D) and the effect sound (W)
8 Level 0 - 127 0-127 Output level
No Parameter Value Description
1 Voice Quality
#1
0 - 15 0-15 Audio quality of the telephone voice
2 Treble 0 - 30 -15- +15 dB Bandwidth of the telephone voice
3 Balance #2 0 - 100 D100:0-
D0:100W
Volume balance between the direct
sound (D) and the effect sound (W)
4 Level 0 - 127 0-127 Output level
No Parameter Value Description
1 Type #1 0 - 3 Normal,
Reverse,
Sweep1,
Sweep2
Type of reverb
Normal: conventional gated reverb
Reverse: backwards reverb
Sweep1: the reverberant sound
moves from right to left
Sweep2: the reverberant sound
moves from left to right
2 Pre Delay 0 - 125 0.0-100.0 ms Adjusts the delay time from the
direct sound until the reverb sound is
heard.
3 Gate Time 0 - 99 5-500 ms Adjusts the time from when the
reverb is heard until it disappears.
4 Low Gain 0 - 30 -15- +15 dB Gain of the low range
