• The 

Bar#

 field:

This field shows the location within the sequence where the
currently displayed tempo change will occur. This is a
bar.beat.tick field.

• The 

%Change

 field:

This field shows, as a percentage of the main starting tempo
(either MASTER or SEQUENCE), the amount of tempo
change that the currently displayed tempo will produce.
Tempo changes are always specified as a percentage of the
main starting tempo setting (not the previous tempo
change), regardless of whether the SEQUENCE or MASTER
tempo setting is currently active. This way, all tempo
changes are automatically re-scaled when the main tempo
setting (either SEQUENCE or MASTER) is changed.

• The 

=Tempo

 field:

This field displays the actual tempo number that will play
once the tempo change is active. This number is automati-
cally computed from the displayed percentage of change
multiplied by the main playing tempo (either MASTER or
SEQUENCE).

To view the entire list of tempo changes, simply modify the

Change#

 field and notice the different settings of the other three

fields as you change it. Even if no changes have been entered, every
sequence has one change—to 100% at bar 1. This is because the
current tempo setting is always returned to when the sequence
plays bar 1, whether it does so by playing from the start or by
looping back to the start.

To insert a new tempo change, enter the location within the se-
quence where you want the change to occur into the 

Location

for inserted change

 field, which is a bar.beat.tick field.

Then press the 

<Insert new>

 soft key. Immediately, a new

tempo change will be inserted into the list, displayed on the screen
with a default value in the 

%Change

 field of 100%. You must now

enter a percentage of the main starting tempo. As you enter the
percentage, the 

=Tempo

 field will show the actual tempo. For

example, to insert a tempo change to 60 BPM at bar 5 from a main
starting tempo of 120 BPM, you must insert a tempo change with a
value of 50% at bar 5 (120 BPM X 50% = 60 BPM).

To delete the currently displayed tempo change, press the

<Delete>

 soft key.

The field at the top of the screen, 

Tempo changes

, is a choice

field with two options: 

ON

 and 

OFF

. If set to 

ON

, tempo changes are

used; if set to 

OFF

, all tempo changes within the sequence are

ignored.
