accel: segment x integer x integer -> segment
accel: sequence x integer x integer -> sequence
accel(segm, int_1, int_2)
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.
Illegal values for int_1 or int_2 may cause arbitrary results; however, no error condition occurs in these cases.
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.
