Midi notes hanging with Logic X

I am having this same issue. When I load any virtual instruments and play a few notes a single note will eventually get stuck; stuck meaning infinitely sustaining. I can only stop the note by switching patches. I am using the latest update of Logic X (10.0.2) with an Axiom Pro 61 Midi Keyboard. This happens without any Midi plugins loaded or any other effects.

Hi Jamie,

I probably not the person to try and answer your question as I tend not to use Hardware with Logic Pro X.... (I'm more an old school Hardware Sequencer person when it comes to external synths) but I can say I know of several people who use the 707 with Logic without issue.... .....so I'm guessing your issue lies with your choice of one of those really cheap usb to midi cables which are known to cause all kinds of weird issues... from hanging notes to sync problems.. and maybe a touch of User error?

So.....

Note: Make sure on the 707, you are pushing SHIFT -> SYNC MODE three times or until you get a message in the LCD that says "5-n", which means the 707 is now following MIDI clock. (I don't know much about the R8 so someone else will have to step in and advise if there are any special setups needed for that)

More detail

1) Enter Track Play mode.
2) Press the STOP button to stop the rhythm if it is running.
3) While holding SHIFT, press SYNC MODE repeatedly to change between the
different sync modes.

Display will show:

5-d = DIN Sync
5-t = Tape Sync
5-n = MIDI Sync
Number (Tempo Value) = Internal Sync

Also read up on the Sync stuff in Logic Pro

http://documentation.apple.com/en/logicpro/usermanual/#chapter=40%26section=0

This is for LP9 but it works much the same way in LPX (making sure you have turned on all the advanced features of LPX in LPX's Preferences/Advanced tab)

jakob,

Then your issue is something else entirely and has nothing to do with the Midi interface.. as there are zero issues using an iConnect Midi device with any 2009/2010 Mac with USB2 ports.....

I suspect you have something else installed in your system that is causing the real issue.... (given you got your Mac from someone else and who knows what they might have previously installed on it) but as to what that might be, is hard to say without physically looking at your Mac in person.

If I were you, I would make a backup of all personal data (Projects, Music, Docs, Photos etc..) to an external HD

Then I would wipe your Mac clean, using the Recovery partition... and then reinstall OS X Mavericks..

OS X Mavericks: Erase and reinstall OS X

Now install LPX and then the iConnect stuff and install nothing else..

Now test in LPX and see what happens.....

Im willing to bet you will then have zero midi notes hanging....

It's likely not a Logic issue..... otherwise a lot more people would have see/reported this issue and that's simply not the case...

Note:

I know it is not my MIDI hardware (MOTU Express)

Have you installed the new Beta drivers for the 128 that Motu released a few days ago to resolve some weird issues with Yosemite and 10.1?

There is a large thread here about this known issue....

Ajita,

The problem likely lies either with your Midi Keyboard, your Midi interface or your Control Surface preferences in Logic..

To test....

First shut down yur Mac.. unplug your Midi keyboard and all other Midi cotnriolelrs and restart Mac.. Now launch LPX and use the built in Musical Typing keyboard to play the notes that are currently giving you issues..

If they play normally then, as i said earlier, the problem lies with those particular items so..

Shut down LPX and delete the Logic prefs and CS prefs as described here...

Delete the user preferences

You can resolve many issues by restoring Logic Pro X back to its original settings. This will not impact your media files. To reset your Logic Pro X user preference settings to their original state, do the following:

1. In the Finder, choose Go to Folder from the Go menu.
2. Type ~/Library/Preferences in the "Go to the folder" field.
3. Press the Go button.
4. Remove the com.apple.logic10.plist file from the Preferences folder. Note that if you have programmed any custom key commands, this will reset them to the defaults. You may wish to export your custom key command as a preset before performing this step. See the Logic Pro X User Manual for details on how to do this. If you are having trouble with a control surface in Logic Pro X, then you may also wish to delete the com.apple.logic.pro.cs file from the preferences folder.
5. If you have upgraded from an earlier version of Logic Pro, you should also remove~/Library/Preferences/Logic/com.apple.logic.pro.
6. Restart the computer. (Very important to do this!)

Now launch LPX and test with your Midi keyboard connected and see what happens..

if the problem continues then the issue lies with your Midi Keyboard and/or Midi Interface

Contact the Manufacturer of the device(s) for assistance as it is not a Logic Issue...

Okay...

A few quick questions/comments..

1) Did you run Midi Monitor without LPX running and did you look for generated data like you saw in your previous post. Also test with Garageband if you have it installed along with another DAW (given you said it doesn't affect other apps) if you can... and again, watch for similar self-generated data issues...

2) Have you actually spoken with Motu support? They are really helpful once you get past the initial "Please install/re-install/reset/unplug" stage

Midi works fine with other apps,

3) Which apps specifically on this same Mac?

4) Although you didn't say so specifically, that I can find.. I assume you have already trashed both Logic's prefs and the CS files... If not, please do so and test again...

1. Quit Logic Pro
2. In the Finder, choose Go to Folder from the Go menu.
3. Type ~/Library/Preferences in the "Go to the folder" field.
4. Press the Go button.
5. Remove the com.apple.logic10.plist file from the Preferences folder. Note that if you have programmed any custom key commands, this will reset them to the defaults. You may wish to export your custom key command as a preset before performing this step. See the Logic Pro X User Manual for details on how to do this. If you are having trouble with a control surface in Logic Pro X, then you may also wish to delete the com.apple.logic.pro.cs file from the preferences folder.
6. If you have upgraded from an earlier version of Logic Pro, you should also remove ~/Library/Preferences/Logic/com.apple.logic.pro.
7. Restart the computer.

Yes, software instruments of course, as Kontakt or any other player, even the built in electric piano has randomly hanging sustain notes.

I have the same problem here, also other users reported this issue.

Was no problem in Logic 9, appears only in Logic X.

This is painful, especially when you have to deal with tough deadlines.

Please dear Logic team, get this fixed apart from many other bugs.

Habe to go back to V9 for a while :-(

No MIDI plugins before the instruments and no specific MIDI interface, just my m-audio keystation 88 keyboard via USB.

It mostly happenes during playback, in my case a string section, notes are hanging until I hit the space bar (stop).

After some more play-stop-play- procedures the notes behave as they should.

But as I said before, this slows down my workflow.

Never had this issue in Logic 9 or any other version or DAW.

Does that particular keyboard come with software to install?

I am not sure. I don't think the Axiom Pro has a driver for Logic X yet. It seemed to be working fine before I updated the firmware on the Axiom Pro and supposedly M-Audio has a Logic X driver in the works, but I don't know.

Any chance of going back to the old firmware, if not I would try the firmware update again in case any data was corrupted.

That said... some older MIDI interfaces/controllers do not seem to work correctly sice Mountain Lion, Apple changed something in their MIDI implementstion.

I'm having the same issue. In most of the virtual instruments, after I play a few notes, a note hangs (infinitely sustains) and the only way to stop it is switching instruments.

iMac running Mountain Lion, Logic Pro X 10.0.2, using a microKorg keyboard (midi to USB) controller.
