Velocity Map
The Velocity Map parameter determines the way the PC4 SE generates MIDI velocity
information. Different maps generate different MIDI velocity values for the same physical
key strike velocity.
The default map (Linear) provides the widest range of velocity expression, but you may want
to choose a different map if the default does not suit your playing style. You can select from
any of the following settings:
Light3
Light2
Light1
Linear
Hard1
Hard2
Hard3
PianoTouch
Easy Touch
GM Receive
Intonation Map
Most modern western music uses what is known as equal temperament. This means that
the interval between each semitone of the 12 tone octave is precisely the same as every other
semitone.
However, many different intonation intervals have evolved over the centuries and across
cultures and instruments, so equal temperament will not sound appropriate for certain styles
of music. The PC4 SE supplies you with 18 different factory intonation maps which are
useful for a range of different styles. Each of these maps defines different intervals between
each of the semitones in a single octave (used for all octaves) by setting pitch offsets for each
note in cents.
6-6
Makes it increasingly easier to produce high MIDI velocity values for the
same key strike velocity (with Light3 being the easiest). These maps work
best for those with a light touch.
The PC4 SE default map. Linear, allows MIDI velocities to pass unchanged.
It follows a linear response.
Makes it increasingly harder to produce high MIDI velocity values for the
same key strike velocity (with Hard3 being the hardest). These maps work
best for those with a heavy touch.
Simulates the general velocity response of an acoustic piano, and is best
suited for playing acoustic piano programs.
Similar to the Light1/Light2/Light3 settings. Makes higher velocities easier
to play, but allows more sensitive control over playing high velocities by not
boosting the MIDI velocity for fast strike velocities as much as it does for
medium strike velocities.
Mimics the velocity response commonly used by keyboards that use the
General MIDI (GM) sound set. The GM Receive map makes medium strike
velocities produce higher MIDI velocities compared to the Linear map.
