I tried to activate midi feedback, but it doesn't seem to work.
I've created Library\Live 5.0\Options.txt but nothing has changed.
Does it only take effect on MIDI notes?

I made a custom controller that triggers clips via midi note messages.
What I wish I could do is to put LED's over my buttons, showing which clips are playing or not.

As quoted at: http://www.teragon.org/wiki/index.php?title=Options.txt

The MIDI feeback option is not necessary anymore, since Live 5 this is enabled anyway. The options.txt stuff is a bit tricky. Things might change here from verision to version... so you can never be sure it does what you think it will do. We implemented this hidden feature to allow modifications of the software which are only usewful for a very smal user group with a very specific setup and for us to have an easy way to test some details. Things we do not want to put in prefs like: enforce compatibility to audio driver X while running under os Y if soundcard Z used port A.... any feature which might be useful for more then ten customers at some point ends up in "public" and not inside the options.txt Robert

Should work out the box.

Hi DJ Grobe, you should allways get the right status info back, but depending on the MIDI driver / hardware we currently cannot ensure 100% that the order of MIDI messages is correct. A solution is to slightly delay all feedack data > 0.(5ms should do the job). This ensures the clip stop message from the currently running clip ( "0" ) will allways be overwritten by the statt message ( "127" ) from the new one.

Hope that makes sense. Happy new year to everybody.

Robert

Well i test now with mac osx, with windows, with m-audio card conectted to monitor etc etc etc.
Multiple configurations....

The first clips played with global play escene, its ok, but after the first, all times i play clips, y have retrun error wrong

TIMESTAMP IN PORT STATUS DATA1 DATA2 CHAN NOTE EVENT
0006D45E 3 -- B0 01 7E 1 --- CC: Modulation
0006D8A5 3 -- B0 01 7F 1 --- CC: Modulation
0006D8A5 3 -- B0 01 00 1 --- CC: Modulation *


This 0 value make my software show the play buttons like off, when ableton continue playing.
Why this robert? why ableton back with 0?
What is the reason for that?

0= clip stoped, so why use 0 on play scene buttons?

I think this its a bug form ableton, because the first time i press play, all its ok, this start happen after start use for secodn ore more times any play scene button.

If you replay same clip, the result its ok, when change to other scenene clips the result its 0.....i think this its bug, robert can confirm why thsi happen?

I cnat understan how delay can fix the situation.........the last message i recive its 0 so mesage its 0.

I tested on 3 machiens with diferent hadware and differents OS and result its the same.

I think real bug exist here.
Please if another person can repeat this same test, that can be usefull.

Seems like a bug to me, delay won't help, like you said, it's the last message.

Roll out Ableton 6.04 :lol:

My controller doesnt use Global Plays but people could do, hope they fix it soon :)
