Values between the given points will be calculated by linear, power or cosine function interpolation. The optional interpolation exponent follows the keyword ipl . The default for interpolation is 0, that is linear. If ipl is followed by off , the result a step function instead of interpolation. A parameter file consists of one or any number of fields.
Fields are comparable to clouds or streams in granular synthesis systems.
Depending on the structure of the instrument there can be other parameters. Every field must have a header that is marked by the letter f . Then follow the start and the end time of the field in seconds. After the header begins the block with parameter descriptions for p1, p2, p3 etc. The field description ends after the last given parameter px or with a declaration of a next field.
