I noticed that oscil3 produces waves less sharp than oscili, but not enough smooth as the
smoothness of cubic interpolation routines provided by GEN06 and GEN08. I tested it with
four-point and two-point sine tables, and compared it with tables generated by GEN06 and
GEN08. I opened a wave editor and zoomed the waveform to few cycles to see the sharpness.
Is it normal or we have to deal with a wrong formula?

I tested it with this .csd file (with DirectCsound 2.502, which implements the new opcodes
of 3.50 canonical version).
I attached the example to this message. Any idea?
