Here's something I noticed: I created a degenerate AUX envelope with all
levels set to +0. Then I patched the envelope to control pitch. Since
the envelopes are bipolar, I would expect all possible modulation types
(AuxEnv<, AuxEnv+ and AuxEnv+-) to have no effect, since the envelope
is flat and centred. In practice, AuxEnv+ does this, but AuxEnv< and
AuxEnv+- shift the pitch. I can only assume that the envelope is not
regarded as bipolar for the purposes of setting the modulation limits
(in other words, the envelope is treated as +0..+100). If I get a
chance, I'll try it on the Audity as well.
