Keymap and Sample Editing
The Keymap Editor
using the LoKey and HiKey parameters on the LAYER page in the Program Editor. If each layer
covers the entire range, then each note you played would trigger 20 voices (one for each layer).
You would only hear one drum per note because all the other layers are triggering “Silence.”
Because of the voice-stealing algorithms in the PC3A, the voices would almost immediately
become available again, since they have no amplitude. But for one brief instant, the voice would
be triggered, which could cause other voices to be cut off.
You can also create multi-velocity keymaps—that is, keymaps that will play different timbres
depending on the attack velocities of your Note On events. Program
6 Pop Power Piano
, for
example, uses a keymap with three velocity ranges. Each key range in a multi-velocity keymap
contains two or more distinct sample roots that the PC3A chooses between, according to the
attack velocity of the note. See
Velocity Ranges (VelRng)
on page 14-5
for details.
The Keymap Editor is nested within the Program Editor. The first step in using the Keymap
Editor is to select the keymap you want to edit. This is done on the KEYMAP page in the Program
Editor, using the Keymap parameter. Once you’ve done this, just press the
Edit
button, and you’ll
enter the Keymap Editor. If you want to edit a different keymap, press the
Exit
button to return to
the KEYMAP page in the Program Editor and select the desired keymap. If you want to build a
keymap from scratch, start with the keymap
999 Silence
(see
Building a Keymap
on page 14-7
).
This keymap template contains one key range from C 0 to G 10, and is a convenient starting point
for adding key ranges and assigning sample roots. The Keymap-editor page looks like this:
