+#X text 8 145 Bonk's two outputs are the raw spectrum of the attack
+(provided as a list of 11 numbers giving the signal "loudness" in the
+11 frequency bands used) \, and the "cooked" output which gives only
+an instrument number (counting up from zero) and a "velocity". This
+"velocity" is the sum of the square roots of the amplitudes of the
+bands \, normalized so that 100 is an attack of amplitude of about
+1 The instrument number is significant only if Bonk has a "template
+set" in memory.;
+#X text 580 35 Set low and high thresholds. Signal growth must exceed
+the high one and then fall to the low one to make an attack. The unit
+is the sum of the proportional growth in the 11 filter bands. Proportional
+growth is essentially the logarithmic time derivative.;

+#X text 9 33 The Bonk object takes an audio signal input and looks
+for "attacks" defined as sharp changes in the spectral envelope of
+the incoming sound. Optionally \, and less reliably \, you can have
+Bonk check the attack against a collection of stored templates to try
+to guess which of two or more instruments was hit. Bonk is described
+theoretically in the 1998 ICMC proceedings \, reprinted on crca.ucsd.edu/~msp
