p. 86
Check the send level to each eect.
The eect won’t be obtained if the send level to that eect is set
at 0. Even if the send levels to the eect is set above 0, the eect
won’t be applied if the multi-eect output level, or reverb level
are set to 0. Check each of these settings.
p. 59
You specied a delay time
value (for example for
multieect 43: DELAY) as
a note value, but there’s
a limit beyond which the
delay time will not change
Check the delay time setting.
Increase the tempo.
Since the delay time has an upper limit, specifying the delay time
as a note value and then slowing down the tempo may reach
this upper limit. The maximum delay time is the highest value
that can be specied numerically (i.e., other than in terms of a
note value).
