Plug-ins  Using the Tap Tempo function
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 DELAY will change from 250 ms to 247.9 ms.
*a: Approximate values are used for the calculation results.
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 Plug-in 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.
