The KEYMAP Page
Use the AltControl parameter to specify a control source that will cause the sample to begin
or end at the Alt point. Then use the AltMethod parameter to choose between switched and
continuous calculation of the Alt point. If the value of AltMethod is Switched, the Forte SE
will use the Alt point when the relevant control source is at a value greater than 64 at Note
Start. If AltMethod is Continuous, the Alt point will vary depending on the value of the
relevant control source at Note Start.
As an example, suppose you're working with a flute keymap and wish to control the amount
of chiff heard at the beginning of the sound. On the KEYMAP page in the Program Editor,
set AltControl to MWheel. Now the Mod Wheel controls how much of the initial sample
attack is used. If you set AltMethod to Switched and move the Mod Wheel at least half-
way up, at Note Start the sample will begin at the pre-set alternate start point (in this case,
slightly past the initial chiff). If you set the AltMethod to Continuous, the Forte SE will
interpolate the sample's starting point based on the position of the Mod Wheel. If the Mod
Wheel is 75% of the way up at Note Start, the sample will begin 75% of the way between
normal and alternate start points.
Emulating Legato Play
If you place the Alt point after the initial attack transients of the sample, then you can use
the Alt Switch to emulate legato playing in an acoustic instrument. Setting the AltControl
parameter to Chan St (Channel State) will cause the alternate sample start point to be used
whenever another note is already being held. (Chan St sends a value of 127 whenever at least
one note is being held in the program's MIDI channel.) This allows non-overlapping notes
to use the sample's standard start point, while overlapping notes will use the alternate start
point. Most of the Forte SE's ROM samples have their Alt points set for purposes of legato
play. In most cases the difference in attacks is subtle, but for some sounds, like drums, the
difference can be more noticeable.
Pno.Resonanc (Kurzweil 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 Pno.Resonanc 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 F, and the effect can be enabled or disabled with assignable switch
