5.Enter your RPN/NRPN MSB value and press the ENTER key to confirm.

6.Press the ADVANCED FUNCTION button, then the DATA 2 key. This assigns the number for the RPN/NRPN LSB.

7.Enter your RPN/NRPN LSB value and press the ENTER key to confirm.

8.Finally, press the ADVANCED FUNCTION button, then the CHAN ASGN key.

9.Enter the channel that the message should be sent on.

10.Press the ENTER key to confirm your selection.

Note: Many specification sheets for synthesizers and other MIDI devices make use of NRPN messages and will give the MSB and LSB values that should be entered for DATA 3 and DATA 2 (See Appendix G). Some sheets may only list the values in hexadecimal format, but the M-Audio KeyStudio 25 requires each value to be entered as a decimal. Use Appendix C at the end of this User Guide to convert hexadecimal values into decimal.

About SysEx Messages and Device ID

MIDI SysEx messages (memory dump, all notes off, master tune, etc.) are global MIDI messages that are not MIDI channel-specific. This means SysEx messages are not transmitted on specific MIDI channels. Instead, SysEx transmits a Device ID number along with any SysEx message. This ID is used to uniquely address a particular destination device within your MIDI setup. Device IDs range between 00–127. To send a SysEx message to a particular device in your MIDI setup, find out which Device ID it responds to, then assign the same Device ID to KeyStudio 25 before starting the transmission.

For most devices, the Device ID is pre-configured at 127 at the factory. Device ID 127 plays a special role, as it can be read by all connected devices, regardless of their individual Device ID setting.

As an example, a device with device ID 50 will not only accept messages that are using Device ID 50, but also messages with Device ID 127. SysEx messages with any other Device ID are ignored.

The Device ID for a SysEx message assigned to a controller can be changed using the DEV ID key. This key is used for varying the global Device ID of the M-Audio KeyStudio 25.

Assigning the Device ID

Press the ADVANCED FUNCTION button, then the DEV ID key to assign a Device ID to the M-Audio KeyStudio 25. When the DEV ID key is pressed, the LED display indicates the assigned Device ID. It is possible to enter a new device ID using the numerical data entry keys, or the +/- buttons. Press the ENTER key to confirm.

If a SysEx message is sent from a device with a Device ID of 127, that message can be read by all attached MIDI receiving hardware regardless of their Device ID settings. If a SysEx message is created by a device with a Device ID other than 127, the SysEx message will only be processed by devices with an identical Device ID. The sent SysEx message will be ignored by devices with a Device ID that doesn’t match that of the sending device.

Memory Dump

Press the ADVANCED FUNCTION button followed by the MEM DUMP key to send out a number of SysEx data packets that represent the 5 user-defined or factory-set presets of the M-Audio KeyStudio 25. This can be used for storing or backing up the contents of the memory presets externally.

It is possible to record a Memory Dump to a standard MIDI sequencer track, much like how you would record notes on a MIDI sequencer track. You can recall the Memory Dump you recorded by playing back the MIDI track containing the recorded Memory Dump, making sure that the M-Audio KeyStudio 25 is selected as the MIDI output for that particular track.

The current controller assignments are not immediately affected by a Memory Dump, or a memory location that is sent to the keyboard. You first need to recall a preset to access the uploaded new settings after a memory dump has been sent to the keyboard.
