I am trying to use 2 M-audio X-session pro midi mixers with Live 7.
They are both running on USB power. One on its own works fine, but when i connect the other into the 2nd USB port, Live won't recognise it.
I have tried selecting all the different ports in the midi pref's but to no avail.

Is there any way of working round this?

I am pretty sure that i changed the CC numbers on the 2nd controller, so they don't conflict with the 1st.

Any help would be grand!

thanks,
barney..

Have you changed the MIDI output channel on the second controller?

Also, there may not be enough USB power for both controllers. Have you tried using a powered USB hub?

Mac? PC?

Thanks for the quick reply!
I'm on a MacBook, 2G ram.
I tried to change the global midi channel with Enigma (the maudio software) to chan2 but it still wouldn't register. Enigma is wierd to use, almost to simple for its own good but not easy at the same time, and the xsession has no way of showing that the data uploads have been accepted.
I haven't tried a powered hub though. the power light is lit on the 2nd controller.......

b..

Enigma is useless. At least it was the last time I used it. Great idea, poorly implemented... M-Audio standard, then!

IMO, you're better off learning to edit the parameters from the X-Session itself.

yeah, i thought that!
I don't think you can edit them. ( i've looked online at the manual, and it says nothing about being able to.)
Maybe the answer lies in the audio midi setup prefs in the mac? I know that you can aggregate 2 different audio interfaces, can you do that with midi?

Aggregation isn't necessary with MIDI.

I don't know anything about your controllers, but I'd be VERY surprised if you can't edit them without software. If you can't, then Enigma must be able to work.

i can't seem to find any info about it on the net, maybe its me being stupid.

thanks for all your help though!
