Midi notes hanging with Logic X

I have a clean install of Mavericks 10.9.1 and Logic Pro X 10.0.6 and I too have been getting the 'midi stuck notes' problem.

This has occurred using either my midi interface built in to my Focusrite Saffire or via the Logic Control app on my iPad 2.

This strikes me as being a bug in Logic Pro X as I've had no problem with this in Logic Pro 9.

This is truly annoying.. I'm having same problem in main stage 3 and logic X. Its really horrific when you're performing and this happens. Has anyone heard of a fix. Is apple planning on fixing this one??

I've had soo many problems with this new version of Logic X. I hope the bugs are worked out soon. I've had to re start logic X, 20 times more than I had to restart Logic 9 because of lock ups and crashes.

No problems with stuck midi notes here.. via Ultralites... nor iConnectMidi2+s and certainly not had this issue using LR at all.. (which i have been using quite a lot recently)

Typically this will be related to the midi interface... and it's drivers... or it's one of the basic USB cable types... which have a rep for issues with the later OS X versions... or some similar issue.

Does the midi 'panic' button in LPX not work when this occurs?

Unfortunately this happens with the Logic Control app on the iPad too so I'm thinking it's not midi interface related as the iPad uses WiFi. The 'panic' button doesn't make any difference so I have to quit Logic Pro X and restart.

Well, it can happen whenever the midi signal gets interupted and that could be caused by many things and not just LPX itself.

As I said, i use the LR a great deal and never had this issue with LPX nor have I had a probem using my midi keyboards or controllers and hung notes so i suspect something else is going on... but as to what is the root cause, it's hard to say in your case. I don't believe it is a specific bug in LPX itself... but of course, I could be wrong.

One possibily unrelated but maybe might help in part tip: Make sure that when you finish using Logic Remote to 'force quit' the app on your iPad after you have finished using it rather than just closing it, so it stops running in the background.. otherwise it can accidentally continue to send data.... and that can cause all kinds of weird problems I have found. The same applies to any other iPad apps that interact or send data to / from your Logic Pro X / Midi keyboards... such as iPad synth apps etc... Always make sure you force quit them on the iPad after use as they can continue to send data and that could be interupting the midi data causing such an issue as you are seeing.

Finally, the fact that panic doesn't work.. is very odd... as that should normally kill all midi data...(It does here every time I try it with both internal and external midi data) which again points me to something else going on...

Can you recommend an inexpensive Midi Interface around the $30 range ?

I don't need another firewire unit as I already have one for my MACBOOK. I'd like to get an additional 5PIN DIN -> USB for my iMAC.

Hello Art of Sound: you have hit the nail on the head. But what inexpensive midi interface will work? I have a robust Focusrite Saffire PRO 24 Firewire unit with a Midi Interface on the back, and it works great although it was about $400. I'd like to spend about $30 tops for another interface just to convert MIDI 5 PIN DIN to USB. I agree those interfaces for $3 that they are promoting all over the web DO NOT WORK anymore. I've looked at iConnect for $89, and Midi Solutions For about $60, yet it seems we shouldn't have to pay $60 just to get a 5PIN DIN to USB CONVERTER that works, agree? btw - I have Logic Pro9 and only got stuck notes with the $3 Midi Interfaces I got on the web after the OSX upgrade as you mentioned. I never got stuck notes before that, and I never get stuck notes on my Focusrite Saffire. Let us know what reasonably priced midi interfaces with drivers that you have found please, Thank you friend. Rock on

Referring to post from Art of Sound: "Just as a bit of additional info on this.. Apple changed the USB 'libraries' in Lion and Mountain Lion to handle USB3 as well as USB2. In doing so they broke some of the not 'completely official' ways some developers implemented USB2 which then requires a firmware update for the USB2 device, a change to the physical hardware itself or a driver update for that device to correct the issue. Not all midi interfaces (and other non midi USB2 devices for that matter) are affected by this because many Devs correctly implemented USB2 handling in the first place rather than take a few 'short cuts' along the way which is why this issue only affects a small number of devices. The 'cheap' midi USB interface Pancenter described, is one of those USB devices that cannot be fixed because of the way it was initially designed and implemented... and doesn't have the capability to be upgraded via firmware nor use drivers.... to resolve the issue"

Doug,

One of the 'things' I tend to harp on about...

...is that i cannot understand why some people spend between 1k and 2k on a Mac.. and then go and want to spend a paltry $30 or $40 on a midi interface and expect then to work without issue...

As I have said often before... Its kind of like buying a Ferrari for 150K and then putting $100 tires on it and expecting it to drive well... The tires will work (sort of) but you are degrading the performance of the Ferrari so much that you might as well be driving a 30K Mustang....

The iConnect Midi 2 + I have, works great.. Cost about $100 and has proven itself to be extremely reliable... and also provides for connectivity with my iPad via both Midi and audio pass thru... A great deal indeed!

Any reasonable priced Midi interface such as the Motu.. will also work well but dont expect to pick one up for $30...

There is a reason why they cost more.. Quality design.. quality development... quality firmware/drivers... quality support.. and so on.... It all adds up to a quality experience in most cases...

Just my opinion... Yours may differ....

Hi Art of Sound -

LOL, Ok I see your point, and I did see that comment before.

I hadn't comprehended that we're really talking about the tires on a Vette or Ferrari. Good point. I just ordered the MOTU as opposed to iConnect for my second interface. Glad it's not firewire as it's a pain rebooting everytime you have to reconnect it. Appreciate the support and connecting. all the best. Doug

There are certain *notes* that (in my case f2 & g2) that

1) either arn't recognized - ( nothing displays in monitor window of clicks and ports environment view)

2) send only a note off command

3) send a note (rarely) that hangs

If I change the octave setting on the controller (Oxygen 49) the problem follows the notes, not the physical keys.

This issue renders my complete keyboard - logic setup useless.

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...

i have a minibrute and the same thing happens it has to be something to do with logic as i can use it fine in ableton 😟

joemars...

Again.. read my last post.... and try deleting prefs including the cs ones..

Yeah will try this, but I should of said, this only happens when I'm using the minibrute synth itself not when using it to control plug ins, etc,

Weird

I've been using Logic Pro X on my MacBook Pro for a year, with no problems what-so-ever. Until last week, when I got a brand new iMac 27" along with a MOTU MIDI Express 128. Now all my MIDI gear freezes up. I have yet to test direct USB from my keyboards (at least the two that have it), but so far MIDI is just out of the question. :/

Did you install the latest motu 10.9 midi drivers?
