[PD] Granular Synth

[Kyle Klipowicz]

Looking in Frank's tutorial for making a drum machine
(/dir/to/pd/doc/tutorials/footils/pddrums), he shows the use of some
cool subblock external objects, t3_line~ and t3_bpe (a breakpoint
envelope), found in iemlib.  These may be what you need to generate
interesting envelopes at a granular level.
