Power Supply; Section 2: Basic Midi Control From Your Axiom - M-Audio Axiom Line User Manual

1.5 Power Supply

If you are using your Axiom with a computer via its USB port, there is no need for an external power supply. Your Axiom will draw its
power from the computer.
However, if you are intending to use your Axiom without connecting to a computer's USB port, then you will need to use an external
power supply. No power supply is included in the box, so please select one that meets the following requirements:
12V DC 250mA – 300mA

Section 2: Basic MIDI Control From Your Axiom

Your Axiom controller will not make any sound unless it is connected to a computer or other external MIDI gear. This is because the
Axiom sends MIDI data when you play it and does not produce sound on its own. Instead, it is used to control a virtual instrument on
your computer or a MIDI sound module to generate sounds.
Programming MIDI data can get complicated at times, so with the Axiom range of keyboards, we have strived to make MIDI programming
as simple as possible. In this section we look at the most common MIDI messages and how to program them on your Axiom.
So to begin, you should familiarize yourself with the function button panel.
This is a good place to introduce you to the way we approach the differences between the Axiom 61 and 49 and the Axiom 25. The
appearance and functionality of the Axiom 61 and 49 are the same, it's just the size of the keyboard that is different, thus when we
give instructions for these models, they are always grouped together. The Axiom 25 looks different and a number of its functions are
accessed in a different way, so for this model we will always give you a separate set of instructions.
