Roland TD-25 Parameter Guide

Multi Eects
21
STEP RINGMOD
This is a ring modulator that uses a 8-step sequence to vary the frequency at which modulation is
applied.
Parameter Value Explanation
Mode RING MOD, ENV OSC
RING MOD: Applies amplitude modulation to the input signal
ENV OSC: Outputs oscillation corresponding to the input signal
Freq Modify -64–+63 Increases/decreases value for all steps
Attack 0–127 Speed at which the modulation frequency changes between steps
Rate 0–127 Rate at which 8-step sequence is to be repeated
Freq Step 1–8 0–127 Frequency of ring modulation at each step
PITCH SHIFT
Shifts the pitch of the original sound. This pitch shift can add two pitch shifted sounds to the original
sound.
Parameter Value Explanation
Pitch1 -24–+12 semi Adjusts the pitch of Pitch Shift 1 in semitone steps.
Pitch1 Level 0–127 Volume of the Pitch Shift 1 sound
Pitch2 -24–+12 semi Adjusts the pitch of Pitch Shift 2 in semitone steps.
Pitch2 Level 0–127 Volume of the Pitch Shift 2 sound
DlyTime 0–1300 msec
Adjusts the delay time from the direct sound until the Pitch Shift sound
is heard.
Feedback -98–+98 %
Adjusts the proportion of the pitch shifted sound that is fed back into
the eect.
Negative (-) settings will invert the phase.
Wet Gain Low -15–+15 dB Amount of boost/cut for the eect sound’s lower range
Wet Gain High -15–+15 dB Amount of boost/cut for the eect sound’s upper range
AUTO PAN
Cyclically modulates the stereo location of the sound.
Parameter Value Explanation
Rate 0–127 Frequency of the change
Depth 0–127 Depth to which the eect is applied
OVERDRIVE
Mildly distorts the sound. The tone quality of the distorted sound is adjusted with a lter.
Parameter Value Explanation
Pre HPF BYPASS, 16–1000 Hz
Frequency of the lter that cuts the low-frequency content of the input
sound (BYPASS: no cut)
Drive 0–127 Amount of distortion
Tone 0–127 Tone quality of distorted sound
ISOLATOR
This is an equalizer which cuts the volume greatly, allowing you to add a special eect to the sound by
cutting the volume in varying ranges.
Parameter Value Explanation
Boost/Cut Low -64–+63
Boosts and cuts the low frequency ranges.
At -64, the sound becomes inaudible. 0 is equivalent to the input level
of the sound.
Boost/Cut Mid -64–+63
Boosts and cuts the middle frequency ranges.
At -64, the sound becomes inaudible. 0 is equivalent to the input level
of the sound.
Boost/Cut High -64–+63
Boosts and cuts the high frequency ranges.
At -64, the sound becomes inaudible. 0 is equivalent to the input level
of the sound.
RING MODULATOR
This is an eect 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 eect.
Parameter Value Explanation
Mode RING MOD, ENV OSC
RING MOD: Applies amplitude modulation to the input signal
ENV OSC: Outputs oscillation corresponding to the input signal
Frequency 0–127 Adjusts the frequency at which modulation is applied.
Sensitivity 0–127 Adjusts the amount of frequency modulation applied.
Polarity UP, DOWN
Determines whether the frequency modulation moves towards higher
frequencies (UP) or lower frequencies (DOWN).
