User Guide Addendum

Version 1.10 Features

MPX R1 Compatibility

Version 1.10 software enables two-way communica­tion with the MPX R1 MIDI Remote Controller.

When the MPX 1 and the MPX R1 are connected, the
MPX 1 will automatically detect the MPX R1. If, for any
reason, connection is broken, the MPX 1 will display

Remote Connection Lost

Improved Knob Ballistics

Improved Knob ballistics speed up the selection of
programs in any of the Sort and Search functions.

New Parameters
A Bypass Level parameter (in the Audio row of the
System menu) allows smooth program load when the

MPX 1 is used in a guitar amp effects loop.
An MPX1/MPXR1 parameter in the Initialize row of the

Sytem menu allows you to reinitialize the MPX 1 for
use with the MPX R1.

New Presets

New factory presets have been designed to take ad­vantage of the MPX R1's remote capability. The MPX
1 presets have been re-ordered so that all of the guitar
presets are grouped from 100-159. The Preset Menu
has been revised accordingly.

Other than those listed here all presets are identical but
may be in new locations. Any program created in
Version 1.0 will work in Version 1.10 with the following
exception:

Programs created with 3 merges in the Routing Map
will be reduced to 2 when loaded. (None of the Version

1.0 presets used more than 2 merges.)
