Ableton Forum

also to help with MIDI setup and debugging, a MIDI monitoring app is very helpful...

for Mac OS X, get MIDI Monitor:

for Windows, try MIDI-OX:

I can only seem to get live to recognise the default global channel (-1). I would like to have the volume sliders on channel 2 but live doesn't seem to pick them up. I'm sure i'm doing something stupid as I used to have working script for this but I can't see what I'm doing wrong now, it's a few years since I've looked at these scripts.

Here is the volume part of the script:

[MixerControls]
# Again enter the appropriate CCs for the respective controls.
# If all sliders use the global channel to send their data,
# you can leave the channels at -1. You can, of course, use
# encoders or knobs instead of sliders.
VolumeSlider1: 10
VolumeSlider2: 11
VolumeSlider3: 12
VolumeSlider4: 13
VolumeSlider5: 14
VolumeSlider6: -1
VolumeSlider7: -1
VolumeSlider8: -1
Slider1Channel: 2
Slider2Channel: 2
Slider3Channel: 2
Slider4Channel: 2
Slider5Channel: 2
Slider6Channel: -1
Slider7Channel: -1
Slider8Channel: -1

Does it need to be -2 or 02 or something else? I've tried a few versions but can't make it work.

I'm using a Evolution MK-249C.

Hi, did you already check this...

fishmonkey wrote:another thing to watch out for is getting the global channel right...

the Ableton script numbers the MIDI channels from 0-15... some controllers number the channels from 1-16 instead, if so you will need to subtract one to get the right global channel number to put in the script...

...maybe it applies to slider channel as well as global channel, just something to check...?

Thanks for the reply. Yeah I did see that, I tried each channel above and below but nothing. I can get the volume sliders to work on the global channel but it just seems to be getting anything to work on any other channel. Is the formatting right for the channel number, like just "2"? So frustrating!

Yes, I'm pretty sure it should just be 2 and not 02 or -2 or anything. Are you sure you're transmitting correctly from your midi keyboard e.g. does manual midi-mapping work (and confirms that it's using channel 2)?

Yeah it works as normal in manual mapping mode and displays the correct channel number, eg 2/10.

I think it must be something to do with the script as I tried to do the same thing with my friend's Oxygen v2 (which is why I'm back to looking at this script in the first place) and I the same thing was happening then.

I can't think of what else to try really.

EDIT: It seems to be working now, im not sure why but I must've overlooked something. Thanks for your help

One more question, is it possible use send 1 on one midi channel and send 2 on another channel?

The Oxygen v2 I'm doing this for only has 8 knobs so if they are assigned to Send 1 is it not possible to use Send 2?

I've set it up so far for Send 1 to be on the global channel (2). Maybe I could use another preset on the same channel? I only get to try this out once a week (on the Oxygen) for an hour so any help would be really helpful.

someone asked a similar question today in this thread:

http://forum.ableton.com/viewtopic.php? ... 0&start=45

the config file does imply that you can set individual channels for each control, but i've never seen any instructions on how to code it...

Cheers fishmonkey.
