Changing The Global MIDI Channel
The X-Session’s global MIDI channel affects only the controllers that have the individual MIDI channel assigned to value 00, as described in the
previous section.
Here is how you change the global MIDI channel:
1. Press GLOBAL CHANNEL (ASSIGN and CHANNEL together). The LCD will display the KEYBOARD and CHAN symbol. The 3-digit display will
show the currently selected global channel, proceeded by a ‘c’.
2. Type in the MIDI channel number (01-16) using the numeric keypad or the +/- keys.
Example: MIDI channel 01 is assigned as global MIDI channel.
Using a combination of global MIDI channel and individually assigned MIDI channels can be a great way of
navigating through your system. With multitimbral instruments such as Reason, it can be easier to just change the
global MIDI channel on the X-Session in order to jump to the next device, rather than operating the software.
Setting Toggle Values For The Buttons
The 10 assignable buttons can each be assigned to toggle between two values. You may for instance want to send out value 15 when you first
press the button followed by value 74 when you press the button for a second time. This is how you do it:
1. Press the Function button labelled DATA MSB 2 times.
2. Type in 15 using the numerical keypad or the +/- keys.
3. Press the Function button labelled DATA LSB 2 times.
4. Type in 74 using the numerical keypad or the +/- keys.
If you want the button to send the same value every time you press it, simply type in the same value both times.
RPN/NRPN, GM 1+2 SysEx & Other Messages
As already described, the standard MIDI controller numbers range from 0 to 131. We have extended the list of MIDI CC’s that can be assigned to
the controllers of the X-Session to include RPN/NRPN, MMC and General MIDI 1&2 SysEx messages.
These advanced messages are as easy to program as a regular MIDI CC instruction by entering values 132 to 152 when programming MIDI CC’s.
The charts on page 4 and 5 (or Appendix B) show you what number correspond to each message.
To program the values required for these advanced messages, the X-Session requires you to press the PROGRAM, DATA LSB and DATA MSB
buttons twice respectively. Pressing only once will send the program and bank change instructions “on the fly” as described earlier.
Lets look at a couple of examples to see how this works. Please refer to the chart in Appendix B so you get to grips with the principle:
Assigning MMC Control To A Button
1. Select the button you want to control the MMC message.
2. Press “ASSIGN” on the X-Session.
3. Type in “149” using the numerical keypad. This is the number that corresponds to the MMC instruction, as per the chart on
page 4 and 5.
4. Press “Channel” once.
5. Type in “127”, using the numerical keypad. This ensures that the message is set to all device ID numbers. For more information about this,
please read “About SysEx Messages & Device ID” on page 7.
6. Press the “DATA LSB” button twice.
7. Enter a number from the chart on below to select the MMC message you want:
