+#X text 261 20 CONTROLLING OUTPUT AMPLITUDE;
+#X text 25 263 In this and subsequent patches \, we'll use a subwindow
+\, "output" \, to control overall amplitude. The amplitudes are in
+decibels \, with 100 being full blast. In this example \, you can't
+actually push the output amplitude past 90 or so without clipping.
+You'll know you're clipping if \, instead of an A major chord \, you
+hear a single \, distorted tone two octaves down. The clipping happens
+at Pd's last stage of audio output. All audio signals internal to Pd
+have essentially no level limit.;
