Effects And Tempo Synchronization - Yamaha QL5 Reference Manual

 Using the Tap Tempo function
The average interval (BPM) at which you press the USER DEFINED key will be calculated,
and that value will be applied to the BPM parameter.
The average interval will be input to the parameter.
(the average of a, b, and c)

NOTE
• If the average value is outside the range of 20–300 BPM, it will be ignored.
• If you turn on the MIDI CLK button in the special parameter field, the BPM parameter value will
change in relation to the tempo of the MIDI timing clock received from the MIDI port.
STEP
1. In the Function Access Area, press the RACK button.
2. Press the EFFECT tab in the VIRTUAL RACK window.
3. Press the rack container in which the effect you want to control is mounted.
4. Press the effect type field in the EFFECT EDIT window.
5. In the EFFECT TYPE window, select an effect type that includes a BPM parameter.
6. Set the SYNC parameter ON in the effect parameter field.
7. At the desired tempo, repeatedly press the USER DEFINED key to which you
assigned the Tap Tempo function, to set the BPM parameter.

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
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.
