Midi notes hanging with Logic X

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.

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. :/

Jesse,

You aren't the first to have this problem with new apple hardware and MOTU MIDI interfaces, there was someone about a month ago with the same/similar problem.

The last I heard MOTU was looking into it, I'll see if I can find the thread.

I just checked with a client of mine who has a 2013 iMac and 128 Express and his advice is...

Contact Motu Support as I think they are now privately or semi publicly testing some new Beta drivers that resolve this issue with the 128 and the latest Mac hardware / 10.9.4 or later...

Apparently this issue is caused by changes made by Apple to the USB routines in 10.9.3/4

MOTU is asking if I tried running the Express 128 through a powered USB 2.0 hub... I am away from my home studio, but really curious if that will help at all? Maybe they're suggesting that too long a USB cable, or improper cable, could be the issue? Just thought I would share.

Jesse

I did find a temporary work around though.

I use all my usb devices that have MIDI ports as well (i.e. Focusrite 18/8i, Akai MPK25, Arturia Mini Brute), as an interfaces for all my "retro-like" MIDI gear. I then saved a template file in logic, once I had everything setup (physically and virtually) in my studio. I actually don't get any hanging midi notes with this frankenstien's monster of a configuration. Here's how I have everything plugged in physically... if it helps?

Hello Art Of Noise,

you seem like a clued upfellow. I'm having all sorts of sync problems fro m pro x to my roland drum machines (TR707 & R8) they dont stop start correctly or run in sync. But the strange thing is , I have a MFB 522 drum computer running on the same daisy chain and its running in sync just fine?

VEry strange. I have got a cheapo USB to midi lead tho. Also if I try to send a midi patern out to my MFB it has no polyphony. Only one instument sounds at a time.

my heads gonna explode I think lol

aly feedback would be greatly appreciated

TThank you Art Of Sound,

you ou have restored my faith and confidance in logic. Excellent response my friend. the R8 is a more modern roland drum machine and should have no problems if the Tr707 can sync. I'm gonna go for the iconnect as the midi USB interface. Hopefully this should solve the issue.

thanks again 🙂

Firstly, you are welcome!

Additional..

If you have an iPad/iPhone (and from your post and the "TThank you Art Of Sound," which shows you are suffering from the annoying bug with this forum and iOS devices, it seems you do) and use Midi apps on it..and can afford the extra expense.. I'd highly recommend the iConnectMidi2+ as it's ability to pass through Audio from the iPad to Logic as well as being very stable Midi connectivity wise.. is excellent..and it's built like a tank. So much so that I have two of the 2+ models... and will be buying the larger 4+ version in the next couple of months to take out on the road...

But if not the basic iConnect1 is apparently very stable too... from other reports I've read... though i have no personal experience with that particular model...

Cheers..
