NOTE
• If the EFFECT EDIT popup window used to set TAP TEMPO is open, this popup window is not
displayed.
• With QL V3.0 and later, the delay value (msec) is also shown in the popup window.
Effects and tempo synchronization
Some effects of the QL series can be synchronized with the tempo. There are two such types
of effect; delay-type effects and modulation-type effects. For delay-type effects, the delay time
will change according to the tempo. For modulation-type effects, the frequency of the
modulation signal will change according to the tempo.
Parameters related to tempo synchronization
The following five parameters are related to tempo synchronization.
1) SYNC 2) NOTE 3) TEMPO 4) DELAY 5) FREQ.
SYNC: ......................... This is the on/off switch for tempo synchronization.
NOTE and TEMPO: .... These are the basic parameters for tempo synchronization.
DELAY and FREQ.: ..... DELAY is the delay time, and FREQ. is the frequency of the
modulation signal. These directly affect the way in which the
effect sound will change. DELAY is relevant only for delay-type
effects, and FREQ. is relevant only for modulation-type effects.
How the parameters are related
Tempo synchronization calculates the DELAY (or FREQ.) value
*a
from the TEMPO and
NOTE.
Turn SYNC ON
Change NOTE  DELAY (or FREQ.) will be set
In this case, the DELAY (or FREQ.) value is calculated as follows.
DELAY (or FREQ.) = NOTE x 4 x (60/TEMPO)
Change TEMPO  DELAY (or FREQ.) will be set
In this case, the DELAY (or FREQ.) value is calculated as follows.
DELAY = NOTE x 4 x (60/TEMPO) sec
FREQ. = (TEMPO/60) / (NOTE x 4) Hz
Example 1:
When SYNC=ON, DELAY=250 ms, TEMPO=120, you change NOTE from 8th note to
quarter note
DELAY = new NOTE x 4 x (60/TEMPO)
= (1/4) x 4 x (60/120)
= 0.5 (sec)
= 500 ms
Thus, the DELAY will change from 250 ms to 500 ms.
