controlling Ableton with APC 40 and UC-33 at the same time?

[mwap]

Hi there...

I`m trying to control the Ableton Live with two controllers which are APC 40 and UC-33... But when i try this they both share the same faders even i change the assignments from the midi preferences... How can it be solved? Thanks?

did you try "midi mapping"? and reassigning those faders?

[mwap]

yeah i did... clearly my problem is just on faders. both apc 40 and uc33 are using the same channels on the faders assignment... and i dont know how to change the channels... just the fader mappings collides. the knobs are not!

Hi, You can change the channel on the UC-33 on the device itself and iirc, if you have a UC-33e then you can use the Engima editor to do this quickly. It's all in the UC-33 manual...

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.

But it might also be that the remote surface instant mappings are colliding as well... have you tried testing disabling those in Live's midi preferences?
