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 ********************************************************************** Ted C.
