-The range of this appears to be 0 to 360 (in degrees) as implemented in ARIA, and 0 to 1 in sfizz. Cakewalk range and behavior need to be confirmed.
+This opcode behaves in two different ways in ARIA: non-negative values from 0 to 360 set the phase in degrees, while any negative value randomizes the phase. As implemented in sfizz as of version 1.2.3 the range is 0 to 1 which behaves the same as ARIA's 0 to 360.
