User manual M-AUDIO O2

[. . . ] O2 User Guide English Introduction Congratulations on your purchase of M-Audio's O2. The O2 follows in the footsteps of the mobile USB MIDI controller that started it all--the Oxygen8. Small enough to fit in a bag along with your laptop, the slim-line M-Audio O2 is perfect for throwing down bass lines, programming drum patterns, triggering effects and tweaking virtual studio parameters--anywhere, anytime. You get 25 full-size, half-action, touch-sensitive keys, along with eight fully assignable knobs, 8 fully assignable buttons and other real-time control features for performance and programming. [. . . ] Assign the two toggle values for press (DATA 3) and release (DATA 2) as described above. Program Changes Send out a program change message to the sound card, sound module, instrument or other MIDI device that will receive this standard MIDI message. The program change will be sent on the global MIDI channel. Type in the program number you wish to send, using the numerical data entry keys, or the Preset +/- buttons. Press the ENTER key to confirm. The assignable buttons can be programmed to send out fixed program messages to individual MIDI channels. For further information regarding this method, please refer to the "MIDI Messages Explained" section of this manual Bank Changes If the receiving device has more than 128 programs, access the additional banks by sending out Bank Change LSB and MSB messages. Press the BANK LSB or BANK MSB key on the keyboard. Type in the bank number you wish to send, using the numerical data entry keys, or the Preset +/- buttons. Press the ENTER key to confirm.

RPN/NRPN, GM 1&2, Sys Ex and Other Messages The standard MIDI controller numbers range from 0 to 131. The list of MIDI CC's that can be assigned to the controllers of the keyboard has been extended to include RPN/NRPN, MMC, and General MIDI 1&2 Sys Ex messages. These advanced messages are as easily programmed by entering values 132 to154 when programming MIDI CCs. The charts in Appendix B show which number corresponds to each message. To program the values required for these advanced messages, press the ADVANCED FUNCTION button to enter Program Mode. After entering Program Mode, press the DATA 1, DATA 2 or DATA 3 button.

We strongly recommend a proper soundcard. Refer to www. m-audio. com for a selection of USB, PCI and FireWire audio cards. If you already have an adequate sound card, try reinstalling the latest drivers for the sound card, or try reducing the buffer sizes of the audio drivers. 11 Contact M-Audio If you have any questions, comments or suggestions about this or any M-Audio product, we invite you to contact us by using the following information: M-AUDIO U.
