Type:
accel: segment x integer x integer -> segment
accel: sequence x integer x integer -> sequence
Call syntax:
accel(segm,
int_1,
int_2)
Description:
accel returns the segment which is obtained
from segm by combining it with a linear
tempo profile (accelerando or ritardando)
from int_1 to int_2
quarters per minute.
The values of the tempo parameters int_1 and int_2 have to be between 1 and 255 and indicate the tempo in metronome units (quartes per minute).
This function can also be applied to sequences instead of segments.
Error conditions:
Illegal values for int_1 or
int_2 may cause arbitrary
results; however, no error condition occurs in these cases.
Attention!
This function is based on a music represention model which
will soon be replaced by the more powerful GUIDO Notation
Format; very likely, it will be not supported in this form
in future versions of SALIERI.
