The A/B Glide controller is linked to the front panel A/B button and LEDs.
Pressing the button toggles the state of the controller between A and B, as
indicated by the LEDs.
When the controller is at A, its output is 0. When it is at B, its output is 127.
Controls are provided to allow you to determine the rate at which it glides from
A to B and from B to A.
Of the many presets in the MPX 1 that use this controller, the most straight-
forward example is Rotary Cab. In this preset, A/B is used to glide between the
fast and slow rates of a rotary speaker effect. Different A and B rates are used
to simulate the mechanical inertia of the real thing. Note that you can use the
OnSrc parameter to select other controllers to initiate the glide.
