Also \, partials can come into contact with each -other causing beating. The value of 1423 was chosen to make the beating -effect especially strong if you're running at a sample rate of 44100 -(the usual one.); -#X text 330 616 updated for Pd version 0.37; -#X text 219 245 waveforms:; -#X connect 1 0 15 0; -#X connect 2 0 1 0; -#X connect 3 0 1 0; -#X connect 6 0 7 0; -#X connect 8 0 7 1; -#X connect 9 0 7 2; -#X connect 10 0 7 3; -#X connect 15 0 5 0; -#X connect 15 0 5 1; -- cgit v1.2.1
