For example, if you shift the timbre up 4 semitones, playing C 4 will result in the pitch C
4, but will actually play the sample normally assigned to G
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 Transpose parameter
on the KEYMAP page to -4 semitones, then setting the Pitch parameter on the DSP CTL
page to +4 semitones.
Playback Mode
Setting Playback Mode to Normal plays samples in the selected keymap from their start
point to their end point.
Setting Playback Mode to Reverse plays samples in reverse, from their end point to their start
point.
Setting Playback Mode to BiDirect (bidirectional) causes the samples to loop infinitely,
alternating between normal and reversed playback.
Setting Playback Mode to Noise replaces the samples with a white noise generator.
String Resonance
Sympathetic string resonance in an acoustic piano is the phenomenon of undamped piano
strings resonating as a result of sound from other notes/keys. This can be observed if one
plays a C, continues holding down the key after the sound has decayed, and then forcibly
presses and quickly releases another C key. The undamped strings of the held-down C key
will audibly ring, providing a highly tuned "echo", commonly known as sympathetic string
resonance.
The String Resonance parameter works in conjunction with the FX preset "600 String
Resonance" to emulate the sound of strings resonating in an acoustic piano. When
combined, these two components create KSR (Kurzweil String Resonance). Factory programs
in the Piano category are set up to use KSR, and they provide a good example of how the
two components should be used. When making your own program with KSR, it may be
easiest to use an FX Chain from one of these programs, since they already contain controller
assignments for KSR. In these Programs and Chains the dry/wet mix of the KSR effect can
be controlled with Slider 6, and the effect can be enabled or disabled with assignable switch
button 6. When making your own Chain, the FX preset "600 String Resonance" should be
used for the first box of the Program's insert Chain.
When a layer has the String Resonance parameter set to On, the FX preset "600 String
Resonance" monitors which keys are being held on that layer and uses them to tune the
algorithm in the FX preset. Any audio that passes though the FX preset while these keys are
held will cause emulated strings to resonate based on this tuning. When using KSR, layers
which contain samples of piano notes should have the String Resonance parameter set to
On. Layers that do not play samples of piano notes (such as layers for mechanical key release
