Keymap and Sample Editing
The Keymap Editor
layer using the LoKey and HiKey parameters on the LAYER page in the V.A.S.T. 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 PC3LE, 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 PC3LE chooses between, according to the
attack velocity of the note. See Velocity Ranges (VelRng) on page 12 ‐ 5 for details.
The Keymap Editor is nested within the V.A.S.T. Program Editor. To access the Keymap Editor,
press the Edit button while in Program Mode, then press the V.A.S.T. soft button to enter the
V.A.S.T. 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 V.A.S.T. 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 V.A.S.T. 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 12 ‐ 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:
Parameter Range of Values
Sample Sample Root list
Key Range Variable from C0-G10
Low Key C 0 to G 10
High Key C 0 to G 10
Velocity Range (VelRange) Variable from ppp-fff
Low Velocity (Lo) ppp-fff
High Velocity (Hi) ppp-fff
Coarse Tune –128 to 127 semitones
Fine Tune -49 to 50 cents
Master Transpose -126 ST to127 semitones
Volume Adjust ± 24 dB
