No effect will be applied. When a GM System On or GS Reset
messages (p.152) is received, 00 Thru will be selected for
Insertion Effect.
Effects that modify the tone color (filter type)
01: Stereo-EQ (Stereo Equalizer)
[01H, 00H]
This is a four-band stereo equalizer (low, mid x 2, high).
fig.9-1
Low Freq (Low Frequency)
200/400 [1 (40 03 03)]
Selects the frequency of the low range (200 Hz/400 Hz).
Low Gain
-12–+12 [2 (40 03 04)]
Adjusts the gain of the low frequency.
Hi Freq (High Frequency)
4k/8k [3 (40 03 05)]
Selects the frequency of the high range (4kHz/8kHz).
Hi Gain
-12–+12 [4 (40 03 06)]
Adjusts the gain of the high frequency.
M1 Freq (Mid 1 Frequency)
200–6.3k [5 (40 03 07)]
Adjusts the frequency of Mid 1 (mid range1).
M1 Q (Mid 1 Q)
0.5/1.0/2.0/4.0/9.0 [6 (40 03 08)]
This parameter adjusts the width of the area around the M1
Freq parameter that will be affected by the Gain setting.
Higher values of Q will result in a narrower area being
affected.
M1 Gain (Mid 1 Gain)
-12–+12 [7 (40 03 09)]
Adjusts the gain for the area specified by the M1 Freq
parameter and M1 Q parameter settings.
M2 Freq (Mid 2 Frequency)
200–6.3k [8 (40 03 0A)]
Adjusts the frequency of Mid 2 (midrange2).
M2 Q (Mid 2 Q)
0.5/1.0/2.0/4.0/9.0 [9 (40 03 0B)]
This parameter adjusts the width of the area around the M2
Freq parameter that will be affected by the Gain setting.
Higher values of Q will result in a narrower area being
affected.
M2 Gain (Mid 2 Gain)
-12–+12 [10 (40 03 0C)]
Adjusts the gain for the area specified by the M2 Freq
parameter and M2 Q parameter settings.
+Level (Output Level)
0–127 [20 (40 03 16)]
Adjusts the output level.
02: Spectrum
[01H, 01H]
Spectrum is a type of filter which modifies the timbre by
boosting or cutting the level at specific frequencies. It is
similar to an equalizer, but has 8 frequency points fixed at
locations most suitable for adding character to the sound.
fig.9-2
Band 1 (Band 1 Gain)
-12–+12 [1 (40 03 03)]
Adjusts the 250 Hz level.
Band 2 (Band 2 Gain)
-12–+12 [2 (40 03 04)]
Adjusts the 500 Hz level.
Band 3 (Band 3 Gain)
-12–+12 [3 (40 03 05)]
Adjusts the 1000 Hz level.
Band 4 (Band 4 Gain)
-12–+12 [4 (40 03 06)]
Adjusts the 1250 Hz level.
Band 5 (Band 5 Gain)
-12–+12 [5 (40 03 07)]
Adjusts the 2000 Hz level.
Band 6 (Band 6 Gain)
-12–+12 [6 (40 03 08)]
Adjusts the 3150 Hz level.
Band 7 (Band 7 Gain)
-12–+12 [7 (40 03 09)]
Adjusts the 4000 Hz level.
Band 8 (Band 8 Gain)
-12–+12 [8 (40 03 0A)]
Adjusts the 8000 Hz level.
Width (Band Width)
0.5/1.0/2.0/4.0/9.0 [9 (40 03 0B)]
Adjusts the width of the frequency bands whose gain is
being modified (common to all bands). Higher settings will
make the frequency band narrower.
+Pan (Output Pan)
L63–0–R63 [19 (40 03 15)]
Adjusts the stereo location of the output sound. L63 is far
left, 0 is center, and R63 is far right.
#Level (Output Level)
0–127 [20 (40 03 16)]
Adjusts the output level.
