Roland FP-4 Midi Implementation

21
MIDI Implementation
●0121: Auto Wah
Cyclically controls a filter to create cyclic change in timbre.
●0103: Humanizer
Adds a vowel character to the sound, making it similar to a human voice.
●012b: Ring Modulator
This is an effect that applies amplitude modulation (AM) to the input signal, producing bell-
like sounds. You can also change the modulation frequency in response to changes in the
volume of the sound sent into the effect.
●0125: Tremolo
Cyclically modulates the volume to add tremolo effect to the sound.
●0126: Auto Pan
Cyclically modulates the stereo location of the sound.
No Parameter Value Description

Lpf: The wah effect will be applied
over a wide frequency range.

switch (note)
8 Depth 0 - 127 0-127 Effect depth
9 Input Sync Sw 0 - 1 Off, On Determines whether the LFO for
switching the vowels is reset by the
input signal (ON) or not (OFF).

applied
11 Manual 0 - 100 0-100 Point at which Vowel 1/2 switch
49 or less: Vowel 1 will have a
longer duration.
50: Vowel 1 and 2 will be of equal
duration.
51 or more: Vowel 2 will have a
longer duration.

No Parameter Value Description
1 Frequency #1 0 - 127 0-127 Adjusts the frequency at which
modulation is applied.
2 Sens 0 - 127 0-127 Adjusts the amount of frequency
modulation applied.
3 Polarity 0 - 1 Up, Down Determines whether the frequency
modulation moves towards higher
frequencies (Up) or lower
frequencies (Down).
4 Low Gain 0 - 30 -15- +15 dB Gain of the low frequency range
