Tap

MPX 1 tempo controls are available right on the front panel through the Tempo
LED and the Tap button. Many preset programs are designed with their own
tempo rate settings which are stored with the programs. The front panel Tempo
LED will flash in tempo whenever you load a program with tempo control. This
flashing indicates that the Tap button is active, allowing you to change tempo on
the fly. Whenever you see the Tempo light flashing, simply press Tap twice in
rhythm to establish the rate you want.
You can override these individual tempo rates with a global tempo rate in the
System Setup menu. Tempo is also available as an independent patch source
which can control any effect parameter. (See Chapter 4: Patching and Chapter
5: System Controls.)

A/B

A/B is a unique glide function which allows you to morph between selected
parameters. Most effect parameters (or groups of parameters) can be patched
to the A/B controller. Once a parameter is patched, the A/B controls in Edit mode
allow you to select the rate at which you want to glide from A to B and from B to
A when the front panel A/B button is pressed. You can also assign the glide
function to be triggered by any internal source, such as input level, or by an
internal or external controller.
Many of the presets are designed with A/B patches that allow you to morph
between two effects, glide from slow to fast rotary speakers, start and stop loop
delays, etc. Loading any program with A/B control assigned, will cause the front
panel A LED to light, indicating that the A/B function is active. Press A/B to
activate a glide from the parameter values assigned to A to the parameter values
assigned to B. Press A/B again to glide back to the A parameter values. (When
you want to change the A/B parameters, control A/B remotely, assign a trigger
source, or alter the rate of glide, refer to Chapter 4: Patching and Chapter 8:
MPX 1 Internal Controllers.)
