User manual ALESIS PHOTONX25 ASIO

[. . . ] USB MIDI Controller and Stereo Audio Interface Driver Installation Guide Plug-and-Play Connection to a Computer Driver installation is not required on Windows XP since the Photon is supported by the default audio drivers, but we highly recommend installing the Alesis audio drivers. Our drivers will yield significantly lower latency and better performance. [. . . ] Your sound module or software should respond to the Photon X 25's MIDI data. If not, refer to the troubleshooting instructions later in this guide. Experiment with the Photon X 25's OCTAVE buttons and pitch and modulation wheels. Since the two wheels are mapped to MIDI's standard pitch and modulation commands, they should work for you in most cases right off the bat. 2. 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 RECALL 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. Each layer is independent (though a knob can be assigned to the same controller value on two or three of the layers). The row-selection lights on the top and bottom always move together. It's not possible to select, say, Layer 1 on the top row of knobs and Layer 2 on the bottom row. 3 3. Audio Recording and Playback To record, connect the OUTPUT from an audio device to the AUDIO IN jacks of the Photon X 25. The Photon X 25 will "slave" to this setting (so long as it is not out of the Photon X 25's range). Adjust the gain of the incoming audio signal using the Photon X 25's INPUT knob. [. . . ] A little time spent experimenting with these settings can yield big improvements in sound quality. 24-bit audio output to 16-bit recording programs The Photon X 25 always sends audio to the computer at 24 bits (high resolution). Some recording programs will only record the 16 most significant bits (compact disc resolution), ignoring the eight additional bits sent by the Photon X 25. [. . . ]
