The wet position specifies how the delay’s wet signal is related to the position of the DPF (Damp Filter).
With the PRE DPF (Pre-damp filter) setting, the signal before passing through the damp filter is used as the
wet signal. In this case, the damp filter is applied only to the delay feedback.
With the POST DPF (Post damp filter) setting, the signal after passing through the damp filter is used as the
wet signal. In this case, the damp filter is applied to all of the delay sound.
As delay units, you can use msec, Meter, Feet, Frame (24, 25, 29.97, 30fps), or Note. The M-400’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
Delay [msec] = Delay [Meter] x 1000 / 343.59 [Meter/sec]
Feet
Delay [msec] = Delay [Feet] x 1000 / 1127.26 [Feet/sec]
Frame (24, 25, 29.97, 30fps)
Delay [msec] = Delay [Frame] x 1000 / FrameRate (24, 25, 29.97, 30) [Frame/sec]
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.
