#X text 35 6 PITCH ENVELOPES;
#X text 125 24 For pitch envelopes \, unlike amplitude envelopes \,
discontinuities are allowed and sometimes you would rather the envelope
generator actually jump to zero when it's triggered. The "adsr" object
does this for you if you send a negative trigger instead of a positive
one:;

#X text 363 331 pitch env;
#X text 37 377 We have added a new table \, mtof \, for converting
audio signals from pitch to frequency. Its range is 1-127 \, so you
want to add a base pitch in before you start reading from it.;
#X text 37 443 This is an extreme use of pitch enveloping. In a real
situation you might want an envelope controlling vibrato depth or the
like instead of straight pitch.;
