Chapter 20 Editing MIDI Events in the Transform Window 505
 Max: Parameter values that exceed the set value are replaced by it. Smaller event
parameter values remain unaltered. This could be used to restrict filter resonance
modulation events above a value of 100, for example, resulting in a softer filter
sound.
 Flip: All parameter values that match the conditions are reversed around a pivot
point (the value defined here). Events above this value are moved by the same
distance below it and vice versa. As an example, you could move a note from E3 to
G#2, if the pivot point value was set to C3. Effectively, the E3 event, which is 4 (pitch)
values above the C3 pivot point is flipped to 4 values below (G#2). This can also be
used to reverse selected note positions around a particular bar or beat, as another
example.
 Mul: The parameter value is multiplied by the set value (accurate to four decimal
places). The effect, and use, of this operation is best illustrated by the Half Speed
preset.
 Div: The parameter value is divided by the set value (accurate to four decimal
places). The effect, and use, of this operation is best illustrated by the Double Speed
preset.
 Scale: The parameter value is multiplied by the top value, and the bottom value is
then added. This is a combination of Mul and Add. If you enter a negative number
here, values can be subtracted from—rather than added to—the value resulting
from the multiplication.
 Range: Parameter values outside the set value range are replaced by the values of
the (range) limits (combination of Min and Max).
 Random: Random values are generated within the set limits.
 +—Rand.: A random value between zero and the set value (positive or negative) is
added.
 Reverse: The parameter value is reversed within its value range (no value can be set
here).
 Quantize: The parameter value is quantized to a multiple of the set value.
 Qua & Min: Like Quantize, but the quantization does not fall below the set value (a
combination of the Quantize and Min functions, with the same set value).
 Expon.: 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 selection condition is selected
(crescendos need start and end points.). Crescendo creates a smooth alteration of
the current parameters, between the set value boundaries.
