Yamaha FX900 - Manual (Page 18)

Accessing & Editing the Parameters
The FX900 edit mode provides access to several important parameters for each effect, allowing you to change the sound of each
effect over a broad range to suit your specific requirements. Once the parameters for each effect have been programmed and fine-
tuned to provide exactly the sound you want, the entire effect program can be stored into one of the FX900's USER memory
locations for later recall and use.
1. The edit mode is entered by pressing the EDIT key
corresponding to the effect group containing the effect
you want to edit — [DYN], [REV1], [MOD], or [REV2].
The parameter abbreviations are displayed on the upper
line of the LCD, and the corresponding data values are
shown on the bottom line (the parameters will be
described in detail in the following sections).

2. Use the cursor ◄ and ► keys to move the cursor to the
parameter to be edited. In most effects, two or more
parameter screens are required, so the next screen will
appear when the cursor is moved past the last
parameter on each screen. The first screen is re­
selected after the last parameter on the last screen. It is
also possible to step through the various parameters
screens by repeatedly pressing the currently select (lit)
EDIT key. The modulation stage danger effect, for
example, has the following three parameter screens:
3. Use the [DATA ENTRY] control or
[A.]
and
[T]
keys to
adjust the value of the selected parameter. If you hold
the
[A]
or [▼] key the data will scroll continuously in the
specified direction. The data will scroll faster if you press
the opposite arrow key while holding either the
[A]
or
[▼] key.
4. The sound of the edited effect program can be
compared with sound of the program prior to editing by
pressing the [COMPA] key. While the [COMPA] key is lit,
the pre-edit program is active. Press the [COMPA] key
again so that it goes out to return to the edited program.
NOTE: To prevent accidental loss of edited data, the
FX900 responds with a confirmation display —
"RECALL OK?" — if you press the [RECALL]
key while editing. If you actually intend to recall
the original (pre-edit) effect and return to the
MEMORY mode, press the [RECALL] key a
second time. If you do not want to carry out the
recall operation, simply press any key other
than the [RECALL] key.
