Effects and tempo
synchronization
Some of the 01V96i’s effects allow you to synchronize the
effect 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 syn-
chronization.
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 rele-
vant only for delay-type effects,
and FREQ. is relevant only for
modulation-type effects.
How the parameters are related
Tempo synchronization uses TEMPO and NOTE to calcu-
late a value that will be the basis for the tempo, and contin-
ues making adjustments so that this tempo basis stays
essentially the same as the DELAY (or FREQ.). This means
that when TEMPO, NOTE, and DELAY (or FREQ.) are
synchronized, and you change any of these values, the
other parameters will be re-set in order to maintain the cor-
rect relationship. The parameters that are re-set and the cal-
culation method(*a) used are as follows.
If you turn SYNC on NOTE will be set
If you edit DELAY (or FREQ.) NOTE will be set
In this case, the NOTE value is calculated as follows.
NOTE = DELAY (or FREQ.)/(4 x (60/TEMPO))
If you edit 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)
If you edit TEMPO DELAY (or FREQ.) will be set
In this case, the DELAY (or FREQ.) value is calculated as
follows.
DELAY (or FREQ.) = original DELAY (or FREQ.) x
(previous TEMPO/new TEMPO)
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= original DELAY x (previous TEMPO/
new TEMPO)
= 250 x (120/121)
= 247.9 (ms)
Thus, the TEMPO will change from 250 ms to 247.9 ms.
*a: Rounded values are used for the calculation results.
Ranges of the NOTE and TEMPO values
The ranges of the NOTE and TEMPO values are limited by
the ranges of the DELAY or FREQ. values. You cannot set
NOTE or TEMPO values that would cause DELAY or
FREQ. to exceed their maximum possible values when syn-
chronized to tempo. This limitation also applies even when
SYNC is OFF.
Special characteristics of the TEMPO parameter
The TEMPO parameter has the following characteristics
that are unlike other parameters.
It is a common value shared by all effects
You cannot stored 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
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 differ-
ently when recalled than when it was stored. To prevent the
effect from changing in this way between store and recall,
the 01V96i 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.
= 1/48
= 2/1
= 1/16= 1/24 = 1/12
= 3/4= 3/16 = 1/2
= 3/32 = 1/6
= 1/4
= 1/8
= 1/1= 3/8
