How can I get the pulse width mod to produce a smooth sound? I have gap sounds as the width gets close to .97. instr 2 kcps expon p4, p3, p5 ; instr 2:
kpw lfo 1, .33, 0 kpw phasor .233 a1 vco2 10000, p4, 2,kpw out a1 endin |

Won't gaps always occur if the pulse width is at times 0? Plus, the manual states that kpw should never be either 1 or 0. Does the following do what you want: instr 2 kcps = 100 kpw lfo .9, .3 a1 vco2 10000, kcps, 2,abs(kpw)+.01 out a1 endin |
