The KEYMAP Page
6-25
When you set this parameter to On, the KEYMAP page changes slightly:
EditProg:KEYMAP||||||||||||<>Layer:1/1||
KeyMap1:1|Grand|Piano|||||||||||||||||||
KeyMap2:None|||||||||||||||||Stereo:On||
Xpose|:0ST||||||||TimbreShift|:0ST||||||
KeyTrk:100ct/key||AltAttackCtl:OFF||||||
VelTrk:0ct||||||||PlayBackMode:Normal|||
SmpSkp:Auto|||||||||||||||||||||||||||||
<more||ALG||||LAYER||KEYMAP|PITCH||more>
An additional Keymap parameter appears. The two keymap parameters are distinguished as
Keymap 1 and Keymap 2. The KEYMAP page parameters will affect both keymaps. When the
Stereo parameter is set to On, the OUTPUT page for the current layer will show an additional
pair of Pan parameters.
To get the samples to play together, set the Stereo parameter to On, and select the same keymap
as the value for both the Keymap1 and Keymap2 parameters. (With some imported sample
formats, such as Akai, you’ll have two keymaps for a stereo sample—for example, Piano L and
Piano R. In this case, select the left keymap as the value for Keymap1, and the right keymap as
the value for Keymap2.) If you select a keymap as the value for both Keymap1 and Keymap2,
the K2661 automatically uses the left side for Keymap1, and the right side for Keymap2.
Once you have the keymaps assigned, go to the OUTPUT page and set the panning for each
sample as desired. Keep in mind that using stereo keymaps reduces the polyphony of the
program. For example, if you had a two-layer program with stereo keymaps in each layer, each
note you play would use 4 of your 48 voices, allowing a total of 12 notes before all the voices
have been used.
If you’re not using stereo samples, you should set this parameter’s value to Off.
Timbre Shift
This parameter works only on multi-sample keymaps, and changes the root selection for each
key you play. With this parameter you can radically alter the current layer’s timbre (basic sound
characteristics). The nature of the change depends on the timbre itself, so this parameter calls for
experimentation. Basically, timbre shifting changes a note’s timbre by imposing different
harmonic qualities onto the note. A timbre-shifted note retains its original pitch, but its
harmonics are those of the same timbre at a higher or lower pitch. Positive values for this
parameter tend to brighten a sound, while negative values darken.
Here’s an example. If you shift the timbre up 4 semitones, then playing C 4 will result in the pitch
C 4, but will actually play the sample normally assigned to G
#
3, and shift its pitch up four
semitones. This will increase the playback rate of the sample, so although the pitch remains
normal, the timbre is brighter. You’d get the same effect by setting the Xpose parameter on the
KEYMAP page to -4 semitones, then setting the Adjust on the PITCH page to +4 semitones. For
multi-sample layers with narrow key ranges, large amounts of timbre shifting will cause
different sample roots to be played back.
