[comp.sys.mac] Question: Sound Driver and LSC

tedj@hpcid.HP.COM (Ted Johnson) (10/02/87)

Has anyone implemented the LSC sound driver example (by Jan
Eugenides) in the Sept. 1987 issue of "Nibble Mac"? (It uses the
square wave synthesizer to play a 5 note scale, in any one of 5
octaves).  I did, and I kept getting a wierd high-pitched squeal
between the 3rd and 4th notes, on all 5 octaves.
Does anyone know why this occurs? I implemented the program with
LSC v.2.01, and ran it on a Mac SE HD20 with system/finder 4.1/5.5.

This problem also occured when I ran the same program on a MacPlus
running 4.1/5.5.

Any clues are greatly appreciated.

	-Ted
