[. . . ] External Adapter Jack ­ Plug in the AC adapter if you don't want to power the Photon 25 through either the USB connection or four "C"-size batteries. Power Source Selector ­ Press this switch IN to power the Photon 25 from either four "C"-size batteries or an optional external power adapter. If both an AC adapter and batteries are present, the AC adapter will be used rather than the batteries. Leave this switch OUT to power the Photon 25 from a computer's USB connection or to turn off the unit when USB power is not present. [. . . ] Press the encoder to toggle between parameter and value assignments and to accept your entries. Both Windows XP and Mac OS X see the Photon as a plug-and play MIDI controller. Simply plug the Photon into your computer using a USB cable and allow the operating system to install it automatically. Depending on your operating system, the Photon 25 may be identified by your MIDI software applications as either a "Photon" controller or a "USB Audio Device. " No need to worry: the Photon will work regardless of its designation. The Photon is not compatible with earlier versions of Windows or Mac OS. Using the Keyboard with your MIDI software Once you're plugged in and powered up, go to your sound module or software application and set the incoming MIDI channel. If you're using software, you will probably need to configure it to use the Photon or "USB" device. Look for the MIDI device setup menu in your application and ensure that the Photon is designated as an active MIDI device before proceeding. On the Photon, press MIDI CHANNEL and turn the clear encoder knob to select the MIDI channel you specified in your sound module or software. Your sound module or software should respond to the Photon 25's MIDI data. If not, refer to the troubleshooting instructions later in this guide. experiment with the Photon 25's OCTAVE buttons and X/Y joystick. Since the joystick is mapped by default to MIDI's standard pitch and modulation commands, it should work as expected in most cases right off the bat. Using the Knobs with the Supplied Controller Templates If one of the supplied template sets matches your MIDI software, lift the plastic template covers with your fingernail, position the templates, and then replace the covers. Press the PRESET button and turn the clear cursor knob to reach the program number indicated on the templates. You should now be able to control the software according to the templates. Press the LAYER button as needed to cycle through the three knob layers. Each layer is independent (though a knob can be assigned to the same controller value on two or three of the layers). The lights on the top and bottom rows are simply duplicates of one another. It's not possible to have, say, Layer 1 on the top row and Layer 2 on the bottom row. Press MIDI CHANNEL and MIDI PROGRAM at the same time to send the ALL NOTES OFF command to your computer and external devices. [. . . ] If you are using the 5-pin MIDI OUT port to connect to another MIDI device and another device is connected to the Photon's MIDI IN, the MIDI OUT port only sends information from the MIDI IN device, not the Photon. Ensure that any 5-pin cables are connected to the proper inputs and outputs. Photon's 5-pin MIDI OUT not connected to sound source's MIDI IN. Turn the unit's power off, wait a moment, and then turn it on again. [. . . ]
