Effect settings for the AUDIO INPUT
(requires the EXB-SMPL option)
Even in modes other than Sampling mode, the TR's
effects can be applied to the external audio source con-
nected to the AUDIO INPUT 1 and 2 jacks. The effect
section of the TR can be used as a 2-in 4-out effect pro-
cessor.
Routing
In modes other than Sampling mode (i.e., in Combina-
tion, Program, and Sequencer modes) the audio input
routing from the AUDIO INPUT 1, 2 jacks is specified
in the GLOBAL 1.1: System, Audio In page.
1 Enter Global mode from Program mode.
If you enter Global mode from Sampling mode,
the "Input 1" and "Input 2" settings of Sampling
mode will be maintained, and you will not be able
to hear the settings made in Global mode. You
must move here from a mode that can access exter-
nal audio signals (Combination, Program, or
Sequencer). In Sampling mode, the settings you
make here are ignored. AUDIO INPUT 1, 2 set-
tings for Sampling mode are made by the "Input
1" and "Input 2" parameters in the In/Pref page of
SMPL 1.1: Recording (
p.114, PG p.128).
2 Select the GLOBAL 1.1: System, Audio In page.
3 Set the parameters for "Input1" and "Input2."
"Input1" corresponds to AUDIO INPUT 1 jack and
"Input2" corresponds to AUDIO INPUT 2 jack.
"Level": Set the signal level from AUDIO INPUT 1
and 2. Normally you will set this to 127. If the sound
is still distorted even when this level is lowered sig-
nificantly, it is possible that the distortion is occur-
ring before the AD converter. Adjust the [LEVEL]
knob or the output level of your external audio
source.
"Pan": Set the panning of the signal from AUDIO
INPUT 1 and 2. When you are inputting a stereo
audio source, you will normally set Input 1 to L000,
and Input 2 to R127 (or Input 1 to R127, and Input 2
to L000). When you are inputting a monaural audio
source, you will normally set this to C064.
"BUS (IFX/Indiv.) Select": In the same way as for
the oscillator of a program, specify the bus to which
the external audio source from AUDIO INPUT jacks
1 and 2 will be sent (
p.112).
"Send 1," "Send 2": Specify the send levels from the
AUDIO INPUT 1, 2 (external input sound) to the
master effects, in the same way as for the program
oscillators. This setting can be made only if "BUS
(IFX/Indiv.) Select" is L/R or Off (
If "BUS (IFX/Indiv.) Select" is set to IFX, this is set
by "Send1 (MFX1)" and "Send2 (MFX2)" (Setup
page) after the sound has passed through the insert
effect.
About dynamic modulation
(Dmod)
Dynamic modulation (Dmod) is a function that lets
you use MIDI messages or the TR's controllers to con-
trol specific effect parameters in realtime.
BPM/MIDI Sync is another function that controls
effect parameters, and is used to synchronize the LFO
speed of modulation-type effects or the delay time etc.
of delay-type effects to the tempo of the arpeggiator or
an external sequencer.
For details on each of these functions, refer to PG p.221.
Setting example:
We will show how you can use dynamic modulation to
control an effect parameter in realtime.
1 As described in the procedure for "Effect settings
for a program" (
Delay. Verify that a delay sound is being output.
2 Select the PROG 7.1: Ed-InsertFX, IFX page.
Using the Dmod function to vary the delay level by
pushing the joystick
3 Set "InLvl Mod" to +100.
4 Set "Src" to JS+Y#1.
The joystick will control the input level to the effect.
When you set "Src" to JS+Y#1, the delay sound will
no longer be output; however it will gradually
increase as you move the joystick away from your-
self.
p.113).
If "BUS (IFX/Indiv.) Select" is set to other than Off
and "Level" is raised, the external audio source
will be input to the TR. At this time, if audio cables
are connected to the AUDIO INPUT 1, 2 jacks, any
noise component will be input to the TR even if
there is no actual audio input, and (depending on
the settings) will be output from the AUDIO OUT-
PUT L/MONO, R, 1, 2 jacks. If you are not using
an external audio source, and are playing only the
internal programs, combinations, and songs, you
should set "BUS (IFX/Indiv.) Select" to Off, or set
"Level" to 0.
If audio cables are not connected to the rear panel
AUDIO INPUT 1, 2 jacks, the input to the TR will
be 0.
p.112), set "IFX" to 49: LCR BPM
