MarceloAn Posted February 1, 2011 Share Posted February 1, 2011 Hello I was wondering if someone could help me out here A few days ago I noticed that volume tracks in logic go down on its own. Automation is disabled and it always happens in different areas of the proyect, randomly I didn´t have this problem before, so I really don´t know what to do and I couldn´t find anything online I´m using Logic Pro , version 9.1.3 (1697.87) 32 bits Running on a macbook pro with snow leopard 10.6.6 If someone gives me a hand with this, my life would be saved! Thank you! Quote Link to comment Share on other sites More sharing options...
Scott Jackson Posted February 1, 2011 Share Posted February 1, 2011 Select one of the regions on a track where the volume changes. Then press E to open the Event List. Look for Volume data Controller 7 events. If you find them, select them and delete them. If this is not the issue, do you have a MIDI controller connected to your computer. It could be sending random MIDI events. Try unplugging the controller and see if you still have the issue. Quote Link to comment Share on other sites More sharing options...

MarceloAn Posted February 1, 2011 Author Share Posted February 1, 2011 Hey! The problem came back again. Last night i tried resetting both my midi controlled and my m-audio fast track pro, but the volume goes down on its own randomly again. Any other ideas?

Did you test to see if the problem occurs even when the MIDI controller is unplugged? If it does, then it's not your keyboard. 2. What MIDI controller do you have?

MarceloAn Posted February 1, 2011 Author Share Posted February 1, 2011 The problem is that sometimes it can go on for 10 minutes without doing it, so I´m never really sure But i just tried sliding data entry up to 125 and then the volume went up on the track view and the problem hasn´t come back yet, so chances are my midi controller is not working as it should. I got a cheap one, a 2 octave midiplus 25 Origin controller, but i´ve had it for 3 years this is the first time I run into this problem. I had no problem with it using Sonar. Also, I´m using Miroslav Philharmonik, so if the volume goes down in one track, it mutes all of the tracks because it looks like Apple hasn´t figured out a better way to work with multitimbral synths... Anyway, i´ve the same issue with audio tracks Quote Link to comment Share on other sites More sharing options...

MarceloAn Posted February 1, 2011 Author Share Posted February 1, 2011 I´ve tried it, and it doesnt do it when it´s off, but I should try it longer, and let you know what happens afterwards. thanx! Quote Link to comment Share on other sites More sharing options...
Jordi Torres Posted February 1, 2011 Share Posted February 1, 2011 Your controller is sending control change data, controller 7 (volume) to be exact. Logic's faders respond to this controller by design. You didn't experience this in Sonar because its faders don't react to CC7 (unless you want them to, I suppose). A quick fix is to go to Settings > MIDI > Input filter and check the "Control Changes" box. this will prevent the CC7 data to reach your faders. The downside is that it will also filter all other control change data (expression, modwheel, etc). Another fix that filters CC7 only, is to patch a transformer object between the physical input object and the sequencer input objects as in this pic (ignore the one labeled "Filter 10"). http://www.logicprohelp.com/files/filter_7_and_10_147.png J.
