6. Editing
There are no hard-and-fast rules for effect editing. As you
gain experience you'll undoubtedly develop a style that suits
your individual needs. In general, however, you'll need to
divide the process into several steps:
3.
4.
Decide which effects you need.
Decide how they should be connected (i.e. which
algorithm and how the effects are assigned to the
algorithm blocks).
Edit the effect parameters if necessary.
Store the effect.
In some cases you'll also need to make controller
assignments, and you can use the UTILITY mode TITLE
EDIT function (page 42) to give your effect an original name.
In this section we'll cover the operations necessary to
complete the basic editing sequence described above.
■ Effect Group Switching
The FX900 effect groups — and therefore the currently active
effects in each group — can be individually turned ON or
OFF by using the EFFECT ON keys — [DYN], [REV1],
[MOD], and [REV2]. Pressing any of these keys alternately
turns the corresponding effect group ON (key lit) or OFF (key
out). When a stage is turned OFF, it is bypassed and
essentially "removed" from the algorithm. This makes it
possible to hear the various effects in an algorithm
individually or in any desired combination. You won't always
want to use all four effects for every program you create, so
unneeded effects should be turned OFF.
NOTE: The ON/OFF status of each effect is stored to the
RAM memory along with all other effect data when a
STORE operation is performed (see "Memory Store"
on page 18).
