*1: This setting is specified as a note value relative to the sequencer's tempo.
Note values that you can specify:
Thirty-second note Sixteenth note
Eighth note Quarter-note triplet
Half-note triplet Dotted quarter note
Whole note
However, you can't select a setting that would cause the delay time to exceed approximately 2,000 msec.
*2: Choose from the following Timing Patterns.
P01
P02
P03
P04
P05
P06
P07
P08
The cycle of the Timing Pattern is based on a 4/4 time signature.
You can use Rate to adjust the synchronization speed as follows.
Rate maximum: One cycle of Timing Pattern corresponds to one measure.
Rate minimum: One cycle of Timing Pattern corresponds to a 32nd note.
By changing the Rate setting you can change the cycle in the range between a 32nd note to one full measure.
*3: Set Balance to the center value, adjust PITCH to raise the frequency of the sine wave, and set Threshold so that the sine wave is heard appropriately for the input source.
After you've finished setting the Threshold, adjust the Pitch and Balance. This is a useful way to strengthen a kick drum.
