Troubleshooting

Axiom Pro is a professional keyboard controller that has been tested under a wide variety of conditions to ensure trouble-free performance. However, in the event that you do experience difficulty while using Axiom Pro, this section provides tips to help resolve some basic issues that you may encounter.

1.My Axiom Pro keyboard suddenly stopped working after having performed well since installation.

Close any music applications you are using, switch Axiom Pro off, and restart your computer. Once your computer has completely restarted, switch Axiom Pro back on and try again to see if the problem resolves.

2.I have connected a sustain pedal to my Axiom Pro, but its operation is reversed (i.e., the notes sustain when the pedal isn’t pressed, but the notes stop sustaining once the pedal is pressed).

The polarity of the sustain pedal is determined by the keyboard upon startup. When Axiom Pro is powering up, the sustain pedal is assumed to be in the “up” (i.e., off) position. It is important that the sustain pedal is not pressed down during startup, otherwise its operation may be reversed.

3.I have connected the keyboard to my computer with the USB cable, but I cannot locate the Axiom Pro USB keyboard in my software’s MIDI devices dialog box.

Solution 1: Axiom Pro may not be receiving enough USB bus power to function correctly. Try plugging Axiom Pro into a different USB port or use an optional 9V, 500mA power supply to see if the problem resolves.”

Solution 2: In Windows XP, Axiom Pro will appear as “USB Audio Device” if the optional drivers have not been installed. Select “USB Audio Device” as your audio and MIDI input and output device. See the printed Axiom Pro

Quick Start Guide for instructions on how to install the Axiom Pro drivers.

4.My virtual instrument software (or hardware MIDI module) always recalls the sound next to the program change number that I have sent to it from Axiom Pro. For example, if I send a program change number 40 (Violin), my MIDI module or software loads sound number 41 (Viola).

This behavior is normal. Some MIDI devices count their sound presets from 1 – 128 instead of 0-127. As a result, there may be an offset of +/-1 between the program change number sent from the keyboard and the recalled sound preset on your module.
