Section 6: Troubleshooting

The Axiom has been designed to give you high performance MIDI control. It has been tested under a wide range of systems and operating conditions. However, there are virtually limitless numbers of operating scenarios, any of which could affect your system’s performance. Though this section cannot cover all possible situations you may encounter, we would like to offer some suggestions for dealing with common problems.

If you are connecting to a computer, we recommend that you avoid connecting too many devices to your computer at the same time. The more devices you have connected to the computer, the greater the load on the computer’s CPU. Although it is possible in theory to connect multiple USB devices at the same time, doing so may degrade your system’s performance.

My Axiom suddenly stopped working after having performed well since installation on a computer.

<Switch off the unit and leave it off for 10 seconds. Then restart your computer, power up your Axiom and try again. If the problem persists, you may have to reinstall the drivers for the unit. The latest drivers are available at http://www.m-audio.com.

I have plugged in a Sustain pedal to my Axiom, but it works backwards.

<The polarity of the Sustain pedal is calculated by the Axiom when it is powered up. On power up, the Sustain pedal is assumed to be in the off position. So, if you want the Sustain pedal to be off when it is not depressed, make sure not to press the pedal when you power up.To reverse the pedal polarity, just press and hold the pedal when you power up. Note: this will have to be done each time you power up the Axiom.

I have connected the Axiom to my computer. When I press a key, there is a delay before I hear any sound.

<This delay is known as latency. Latency with MIDI signals is caused at the computer and is not coming from the Axiom. This may be due to the CPU load of the soft-synth you are using. MIDI data is simply control data. MIDI data is read by the soft synth; the soft synth then completes a large number of complex calculations in order to produce the sound you hear, and all of this processing activity takes time. If you already have adjusted the appropriate parameters relating to latency on your sound card, try re-installing the latest drivers for the sound card, or try reducing the buffer sizes of the sound card. If you are using a host application, check its buffer size settings as most applications allow for user adjustment to improve timing.

<PC only: If your soundcard supports ASIO or WDM then you should use these drivers. It is suggested that you avoid using the MME drivers which are older and less efficient in design and will have a much higher latency. In the audio settings for your application please select the ASIO driver if available.

<For more information on latency reduction please consult the knowledgebase at http://www.m-audio.com.
