Delay
As delay units, you can use msec, Meter, Feet, Frame (24, 25,
29.97, 30fps), or Note. The M-300’s delay is based on msec units,
and simply changing the delay unit parameter will not change
the delay time in msec units. This means that after changing the
delay unit, there may be a discrepancy between the msec value
and the value that is displayed in the specified units. If this
occurs, the value is shown in green. To correct this discrepancy,
please re-specify the delay time.
The relationship between Meter, Feet, Frame, and msec is
shown below. (Rounded values are shown as the calculated
results.)
Meter
[msec] = Delay [Meter] x 1000 / 343.59 [Meter/sec]
Feet
[msec] = Delay [Feet] x 1000 / 1127.26 [Feet/sec]
Frame (24, 25, 29.97, 30fps)
[msec] = Delay [Frame] x 1000 / FrameRate
If you specify Note as the delay unit, the delay time will be
determined by the relation between Tempo and Note. In some
cases, the relation between Tempo and Note may mean that the
result would exceed the maximum allowable delay time. If this
occurs, the value is shown in red.
The Note values are as follows:
Off, 1/64T, 1/64, 1/32T, 1/64D, 1/32, 1/16T, 1/32D, 1/16, 1/8T, 1/
16D, 1/8, 1/4T, 1/8D, 1/4, 1/2T, 1/4D, 1/2, 1/1T, 1/2D, 1/1
T signifies Triplet, and D signifies Dotted. For example, 1/4
means quarter note, 1/4T means quarter-note triplet, and 1/4D
means dotted quarter note.

This is a dual-mono delay.
Delay A/B
DELAY UNIT
Specifies the units for delay
Value: msec, Meter, Feet, Frame (24, 25, 29.97, 30),
Note)
TIME
Time between the original sound and when the delay is heard
Value: 0.0–1350 ms
FB (Feedback)
Amount of delayed sound returned to the input of the delay.
The feedback level specifies the amount of sound that is
returned. Increasing this setting will increase the number of
delay repetitions.
Value: 0–100
LO FREQ DAMP GAIN
Low-frequency attenuation of the delay sound
Value: -36.0–0.0 dB
LO FREQ DAMP FREQ
Frequency at which the low-frequency region of the delay
sound begins to be attenuated
Value: 20 Hz–2.00 kHz
HI FREQ DAMP GAIN
High-frequency attenuation of the delay sound
Value: -36.0–0.0 dB
HI FREQ DAMP FREQ
Frequency at which the high-frequency region of the delay
sound begins to be attenuated
Value: 200 Hz–20.00 kHz
