Building a Keymap

Building a Keymap
Read below for detailed directions on manually creating and editing a keymap. To build
a keymap, start in Program Mode and select program 999 Clear Program. Then go to
Program Edit Mode by pressing the EDIT soft button. Next press the KEYMAP soft
button, and the KEYMAP page will appear. The Keymap parameter 999 Silence will be
automatically selected. This makes it easier to recognize the key ranges that have samples
assigned to them when you start assigning samples. You can actually choose any program or
keymap you want to start with, but by choosing these, you are starting with a "blank slate."
With the Keymap parameter still selected, press the Favorite1 button, and you'll enter the
Keymap Editor. The Key Range parameter will be automatically selected, and you see its
values: C 0 to G 10 (the entire MIDI keyboard range). The Sample parameter will have a
value of 999 Silence-C 4.
Now you're ready to start assigning samples to key ranges within the keymap. We'll assume
that you've loaded samples with roots at C 1, C 2, C 3, etc. and that you plan to assign a
root to each octave. To begin, press the ASSIGN soft button. The display will prompt you
to select a sample. Use the Alpha Wheel to scroll to one of your samples, or type its ID on
the alphanumeric pad and press Enter. When you've found the sample you want to use,
press the OK soft button. The display will say "Strike low key..." Trigger A 0 (MIDI note
number 21, the lowest A on a standard 88-note keyboard). The display will change to say
"Strike High Key..."Now trigger F 1 (MIDI note number 29). The display will return to
the Keymap-editor page. The Key Range parameter will show A 0–F 1, and the Sample
parameter will show the sample you selected when you started the range assignment.
Each sample in a key range is automatically transposed based on each sample's RootKey
parameter so that it plays at the correct pitch on the keyboard relative to its root key (see
Editing Samples for details on the RootKey parameter). Other keys within the key range
transpose the sample chromatically relative to the root key. Automatic transposition based on
each sample's RootKey is important if you want your sample to play in tune with other Forte
programs or other instruments. The Forte makes this easy if your samples have the correct
RootKey settings (as the Forte's factory samples do). Generally you should set a keyrange so
that the sample's RootKey (displayed at the end of the sample name) is in the middle of the
range. If you set a key range that does not cover the sample's RootKey, the sample will have
to automatically transpose by many semitones, and will likely not sound correct. Samples
are also limited to an octave of upward transposition from the sample's original pitch. If you
set a keyrange too high based on the Root Key, some samples may not be able to transpose
upward far enough to play in tune, and many keys may play the same note (the highest note
that the sample can be transposed to). Automatic transposition relative to the root key can be
offset using the Coarse Tune and Fine Tune parameters on the Edit Keymap page (see Coarse
Tune and Fine Tune on page 9-6).
