Analysis Grabber


I am having some problems using the AnalysisGrabber (LiveGrabber) plug-in for MaxForLive.
First, I am receiving only 3 signals through OSC. (LoFollower, MidTrigger, MidFollower), I don't receive anything from the other ones. See Attachment.

One more thing, I added one AnalysisGrabber plugin on each of my 4 channel. One detect the bass, one the drum, one the voice and the last one the keyboard. I am sending all information on the same port but with different sender name.
drums/LoFollower 0.232323
keyboard/LoFollower 0.232323
voice/MidTrigger 0.232323
bass/MidTrigger 0.232323

Nevertheless, When I just play one Channel, and stop the 3 others, I keep receiving datas from the playing channel.
For instance I play the drums only, and I am receiving the drums datas to my voice channel. See Attachment

I don't know if there is a way to fix this problem or if I am doing something wrong.

Many Thanks.

Hi Mathieu,

Try the following:
- remove the GrabberSender plugins from your audio tracks.
- put one GrabberSender on your Master track.
- in the various AnalysisGrabber plugins, change the Addresses to be unique. So for example, in track 1, name them /LoFollowerDrums, /LoTriggerDrums, etc. In your voice track, change them to /LoFollowerVoice /LoTriggerVoice, etc.

Does this solve your problem?

Hi Mattjis,

Thank you, It resolved my problem of receiving datas even when my channel wasn’t playing.

But I still don’t receive any information from

For all my channel..

Any Ideas ?

Hi Mattijs,

i think i found two small bugs in version 2.7 of your AnalysisGrabber.amxd:

You have a “prepend 4″ instead of a “prepend 5″ at the output of your hi frequency biquad filter. That routes messages to “MidTrigger” instead of “HiFollower”.

And your “change 0.” prevents the triggers to be sent out to “LoTrigger”, “MidTrigger” and “HiTrigger”.

Or did i use on old version?

Hi Karl,

Many thanks for spotting this and isolating the cause! I’ll be checking it tomorrow, hope I can do an update by then.

Hi Karl and maotik,

I updated the plugins, v2.8 should fix the issues.

Thanks again for checking this and isolating the problem!

Thanks for updating so fast and of course for the whole LiveGrabber stuff. I will use the AnalysisGrabber and add pattrstorage preset saving for a current project. Will contribute as soon as i find the time to make it work in a general and reliable way.
