+#X text 37 515 A more sophisticated way to control foldover in sawtooth
+waves is to replace the once-a-cycle jump with a bandlimited transition.
+To get a band-limited transition we synthesize a band-limited square
+wave and harvest the transition from the middle of the top half to
+the middle of the bottom half. Here we use a square wave at SR/10 \,
+so that only partials 1 and 3 fit below the Nyquist. The transition
+should take 1/2 period \, or 5 samples. The table is calculated and
+stored in the "transition-table" subpatch.;
+#X text 40 767 The "band limit" controls how fast the transition table
+is read. If it is set to the Nyquist frequency the table is read at
+0.4 times the Nyquist \, or five samples a cycle. Lowering the band
+limit cuts off the partials of the generated sawtooth wave at frequencies
+below the Nyquist.;
