Sample Skipping (SmpSkp)
Sample skipping is a new feature in V2 K2500 software that allows for increased upward
transposition of samples. By using a new sample playback algorithm, the K2500 increases the
maximum playback rate of a sample from 96 Khz to a maximum of 192 Khz. Needless to say,
though, there is a tradeoff. Unwanted artifacts may be added to a note's sound as the result of
sample skipping. Therefore, the Auto value for this parameter is usually the best choice. Auto
means that the keymap in this layer will only employ sample skipping for those notes whose
upward transposition can be increased. Notes below a certain point would not benefit from
sample skipping and, therefore, Auto ensures that these notes will not use the feature
unnecessarily. The only disadvantage to using Auto sample skipping is that you cannot
pitchbend a note from below the cutoff point into the range of the sample skipped notes.
On means that sample skipping will be employed throughout the range of the keymap. This
eliminates the pitchbend limitation described above, but may add some artifacts to the sound.
Creative types may appreciate this form of distortion, however, so we've made it available.
Off means that sample skipping will not be used at all. Essentially, this means that sample
fetching will be done the same way it was done in pre-V2 software.
Stereo
You'll use this parameter when you're working with stereo samples. When you use the
optional stereo piano programs (included with the RMB-2 daughter board) or load stereo
samples from disk, the K2500 views both sides of the sample as a single sample object. When
you select a stereo sample as the value for the Sample parameter, you'll see the letter "S" as part
of the sample name (for example, "204*StratoBlaster E3 S".
When you set this parameter to On, the KEYMAP page changes slightly:

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 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 keymap as
the value for both the Keymap 1 and Keymap 2 parameters. The K2500 automatically uses the
left side for Keymap 1, and the right side for Keymap 2. Then 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.
This parameter is unnecessary if you're not using stereo samples, and should be set to Off in
that case.
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
