# Effects And Tempo Synchronization - Yamaha RIVAGE PM10 Operation Manual

Plug-ins  Using the Tap Tempo function
The average interval (BPM) at which you press the key will be calculated, and that value will be
applied to the BPM parameter.
The average interval will be input to the parameter.

NOTE
If the average value is outside the range of 20–300 BPM, the tapping sequence will be ignored.

## Effects and tempo synchronization

Some effects 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 parameters 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
parameter values.
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)

from the TEMPO and NOTE
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.
Example 2:
When SYNC=ON, DELAY=250 ms, NOTE=8th note, you change TEMPO from 120 to 121
DELAY = NOTE x 4 x (60 / new TEMPO)
= (1/8) x 4 x (60/121)
= 0.2479 (sec)
= 247.9 (ms)
Thus, the TEMPO will change from 250 ms to 247.9 ms.
Special characteristics of the TEMPO parameter
The TEMPO parameter has the following characteristics that are unlike other parameters.
• The TEMPO parameter can be shared by multiple effects.
• You cannot store it to or recall it from the Effects Library. (You can store it to and recall it from
a scene.)
This means that the TEMPO value may not necessarily be the same when an effect is recalled as
when that effect was stored. Here is an example.
Store the effect: TEMPO=120  Change TEMPO to 60: TEMPO=60  Recall the effect:
TEMPO=60
Normally when you change the TEMPO, the DELAY (or FREQ.) will be re-set accordingly. However
if the DELAY (or FREQ.) were changed, the effect would sound differently when recalled than when
it was stored. To prevent the effect from changing in this way between store and recall, the RIVAGE
PM10 system does not update the DELAY (or FREQ.) value when an effect is recalled, even if the
TEMPO is no longer the same as when that effect was stored.
* The NOTE parameter is calculated based on the following values.
