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 1022 Clear Program. en go to
Program Edit Mode by pressing the Edit button. Next press the KEYMAP soft button, and
the KEYMAP page will appear. e Keymap parameter 999 Silence will be automatically
selected. is 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 Edit button, and you’ll enter the
Keymap Editor. e Key Range parameter will be automatically selected, and you see its
values: C0 to G10 (the entire MIDI keyboard range). e 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. e 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. e display will say “Strike low key…” Trigger A 0 (MIDI note
number 21, the lowest A on a standard 88-note keyboard). e display will change to say
“Strike High Key…”Now trigger F 1 (MIDI note number 29). e display will return to
the Keymap-editor page. e 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 on page 9-10 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 SE programs or other instruments. is is easy if your samples have
the correct RootKey settings (as the included 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 oset using the Coarse Tune and Fine Tune parameters on the
EditKeymap page (see Coarse Tune and Fine Tune on page 9-5).
