APPENDIX G

USING THE MULTIVERB ALPHA 2.0 WITH AN X-15 ULTRAFOOT

When an ART X-15 ULTRAFOOT is used with the ALPHA 2.0, remote

control of the parameters and the ability to turn on and off the

effects themselves greatly extend the capabilities of the ALPHA

2.0. More than half of the ALPHA 2.0's factory presets are set up

with MIDI controllers providing you instant access to the

parameters with your X-15.

You do not need to reprogram the X-15 ULTRAFOOT for use with the

ALPHA 2.0. All programming and setup is done with the ALPHA 2.0.

Add a MIDI Controller to the ALPHA 2.0 preset and edit the

parameters. The default settings allow for almost instantaneous use

with both devices. Refer to the example in Appendix B, Adding

Performance MIDI to an Existing Preset.

To correctly hook up the two devices, two MIDI cables should be

used (see the hookup diagram on the preceding page). Both the ALPHA

2.0 and X-15 "talk" to each other keeping their status' up to date.

When the X-15 is in Effect Mode, it will display which effects in

the preset are active by lighting the associated pad's LED. If you

add, delete, or change the status of an effect with the ALPHA 2.0,

the X-15 will monitor and display (or not display if you remove or

turn off an effect) the change.

All of the presets in the ALPHA 2.0 with MIDI controllers assigned

to them are set to be controlled by MIDI Controllers (MC) 4 and 11.

On the X-15, the left expression controller is MC 4 and the right

pedal is MC 11. When adding a MIDI controller to a preset in the

ALPHA 2.0 the default value for the MIDI controller (screen 2,

CONTROLLER IS) is MC 4, Foot Controller. To select another MIDI

controller, use the Encoder to change the Value while editing this

screen.

Every time a message is sent from the X-15 to the ALPHA 2.0, the

Alpha's LCD displays the message sent. Effects on and off messages

and real time pedal values will be displayed, program change

messages (preset changes) will not be displayed. For effects on and

off messages to be displayed the X-15 must be in Effect Mode.

Anytime either foot controller is moved, the ALPHA 2.0 displays the

parameter name and value.

To control the output level of any ALPHA 2.0 preset, assign two

MIDI controllers to the preset, use one pedal as the controller,

and control the Dry and Efx parameters of the Mix. See Example 6 in

Appendix B for setting up a preset for level control.
