+#X text 12 41 In this example we use two cascaded bandpass filters
+to troll for partials in Jonathan Harvey's famous bell sample.;
+#X obj 78 487 r totsamps;
+#X text 14 82 Note that filters can give unexpected level changes.
+The bp~ object is designed to have roughly unit gain at teh pass band
+\, so the higher you set "Q" the more amplitude is lost. YOu can correct
+for this by pushing the output amplitude \, but be sure to remember
+to reset the output amplitude before you reduce Q again. I set the
+Q to 100 and the output amplitude to 110 or 120 (with the room gain
+way down.) Then holding the shift key \, slowly drag the center pitch
+upward listening for modes.;
+#X text 16 233 You can hear partials around 48 \, 51.3 \, 55 (faint!)
+\, 57 (fainter!) \, 60 \, two beating partials around 65 \, 67 \, 69
+\, 70.9 \, 71.75 \, 72.6 \, 74 \, 74.65 \, 75.6 \, 77 \, 81.2 \, 84.6
+\, 86.5 \, and probably many more. There's also one down at 36 \, but
+it's easier to see it on the meter than hear it.;
