Assigning An Individual MIDI Channel
1. Select the controller you want to edit as described earlier.
2. Press CHANNEL.
The LCD will display the CHAN symbol and the 3-digit display will show the current channel assignment of the selected controller, preceded
by a ’c’. The small 2-digit display will show the currently selected controller for assignment.
3. Type the MIDI channel number (01-16) you want the controller to send to, using the numeric keypad or the +/- keys.
If the controller is assigned to channel 00, it will transmit on the global channel.
Changing The Global MIDI Channel
The UC-33’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, preceded 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 UC-33 in order to jump to the next device, rather than operating the software.
Setting Toggle Values For The Buttons
The 14 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 UC-33 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 XXX and XXX (or Appendix B) show you what number correspond to each message.
To program the values required for these advanced messages, the UC-33 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:
