Exponent.
The parameter value is scaled exponentially. The extreme values (0 and 127) remain
unaltered. The set value determines the shape of the curve. Positive values result in the
exponential scaling of data (increasing input values remain lower for longer, and then
rise quickly), and negative values result in the logarithmic scaling of data (decreasing
input values remain higher for longer, and then drop off more quickly).
Crescendo
This only works if the Inside position condition is selected (crescendos need start and
end points.). Crescendo creates a smooth alteration of the current parameters, between
the set value boundaries.
Rel.Cres
This only works if the Inside position condition is selected. The effect is similar to that
achieved by Crescendo, but the previous values of the parameters being altered are
taken into account when the crescendo is created, preserving the relative feel of the
original.
Use Map
The set Map will be used when this operation is selected.
Parameter Sets
Presets
The twelve items in the pull-down menu are write-protected presets. You can alter the
presets temporarily, but any changes you make will be discarded when you leave the
preset. Here is a list of the Presets:
• Crescendo
• Scale 14 bit PitchBd (Pitch Bend data will be scaled, keeping the 14 bit information
intact)
• Double Speed (doubles the tempo by halving positions and lengths)
• Half Speed (halves the tempo by doubling positions and lengths)
• Humanize (adds a random value to the position, velocity, and length of notes)
• Reverse Position (reverses the positions of notes within a section)
• Reverse Pitch (inverts the pitch)
• Transpose (transposes the notes)
• Exponential Velocity (alters the scaling of the velocity curve)
• Velocity Limiter (limits the velocity)
• Fixed Note Length (creates constant note lengths)
• Maximum Note Length (limits the maximum note length)
• Minimum Note Length (limits the minimum note length)
• Quantize Note Length (quantizes the note length).
