Sonar bug in PitchBend handling with CS API

[azslow3]

MIDI PB message can not be blocked. If assigned in CS plug-in (Generic Surface, AZ Ctrl or any other), it is still "leaking" to the MIDI track input. Switching wheel off in Preferences does not work, since it also block the signal to the CS Plug-in.

I guess the origin is in the filtering code: it uses 2 bytes comparison. For other messages (Note, CC, etc) that is ok. But in Channel Pressure and Pitch Bend the second byte is a part of value... and so only one value is blocked instead of the whole range.
