Almost everything on the B4 can be controlled by using MIDI controllers,
they just aren't particularly standard apart from:

Expression Pedal (11) - (MIDI Expression)
Leslie Speed (1) - (Mod Wheel - not really "standard", but intuitive)
Tube Amp Volume (7) - (MIDI Volume)

Amongst others, you have:

Upper Drawbars - 12-20
Lower Drawbars - 21-29
Pedal Drawbars - 33-38
Leslie On/Off - 68

...ad nauseum

A long as you can map these controller numbers to a physical controller on
whatever hardware you have, you can control it. Note that using B4 as a
plugin in Emagic Logic screws up all those controller numbers, as Logic
adds an offset.
