Unitor 8 + AMT 8 intermittent

When I boot my computer (10.5.8) and Logic 9 my Unitor 8, stacked with an AMT, is not recognised (used to be until 6 months ago) I can fix this by turning the Unitor 8 off/on and doing a re-scan in AudioMidi but every time I re-boot it is missing again.
The AMT is always recognised. The AMT is plugged directly to my MacPro via USB and the Unitor is connected to the AMT via RS 422 as per Unitor/AMT manual (instructions for stacking)
I've tried re-installing the emagic midi driver (latest version 2.2) and deleting AudioMidi preferences but it will still not recognise the Unitor 8 unless I do the re-scan.
Any ideas anyone?
Thanks
Julian

Hi Bee Jay,
Thanks for that. Does appear to cover the problem. I'm not in the studio at the moment but will try this tomorrow.
The strange thing is that my set-up has been stable for years (both units recognised until a few months ago) so it was working in Logic 6,7 and 8. The Apple support page you linked to is dated 3rd September 08 and it was working post this.

AudioMidi slow

Every time I launch Logic it is really slow scanning midi devices. I've tried uninstalling/re-installing the Unitor 2.5 driver but no difference.
It's not a necessarily a Logic thing as it is slow if I launch any app that uses midi. It's still slow if my Unitor + AMT 8 are turned off. Also if I try a midiscan in AudioMidi or change the configuration it also hangs for about a minute. Deleted AudioMidi preferences and configurations but no improvement.
An earlier boot disc with 10.5.8 doesn't have the same problem (but I can't see any difference between the midi drivers) but it has been present in most recent 10.6 variants.
Any thoughts anyone?
Thanks
Julian

Found the problem!
It was a set of USB Lacie speakers plugged in the Mac keyboard. Must have been creating an issue every time the midi scanned the usb bus. Removed speakers problem gone.

Tiger OSX Driver for eMagic AMT-8 - AMT no longer seen in AudioMidi

Can anyone here tell me where to find the driver for the AMT-8? It seems "missing" from the Apple and Emagic websites. AudioMidi is still not seeing the interface although "About this Mac" sees it just fine.
Also, no driver for it in the Library like my other interfaces.
All previous links to the driver are no longer valid.
Thanks!

That link to the Apple site I've looked at a hundred times. You know, if I look one more time MAYBE it will be there this time. The ONLY one I've seen on there that is close is the Unitor Command software, but that's not quite it. Is it hiding in one of the other 3 folders and I'm just too blind to see it?
If you can email it to me that would be great. Just use the: "[email protected]" address so that I can grab it on the road easier.
Thanks Much!

What happened to Emagic's good old AMT = Advanced Midi Timing in Logic 7, 8

I wonder if anybody knows if Apple dropped the AMT-algorithm enabeling Emagic's AMT 8 and Unitor 8 Mk 1 and 2 to be more accurate in Midi timing than ordinary interfaces without AMT are. The last button/check box that was related to AMT (Advanced Midi Timing) I saw was in Logic 6. Steinberg and Motu had their own timing accuracy systems then.
Since in the whole Logic Studio manual AMT is not mentioned a single time I supposed this very useful tool has been sacrificed by Apple's dingy future spirit.
Not to be misunderstood: I know the interfaces can be installed and are supported and be run by the actual machines and systems as normal Midi interfaces .

Just having a random search around:
http://developer.apple.com/audio/pdf/coreaudio.pdf
"The MIDIPacketList are a time-stamped list of packets to or from one endpoint.
All MIDI I/O functions use this structure. The MIDIPacket contains one or
more simultaneous MIDI events."
Also, back when Logic was first going in OSX, emagic had an article about this as well, although that's long since gone.
OSX's time stamping isn't exactly the same as AMT in detail, but is in essence the same thing. AMT works by time stamping events ahead of time, so the interface can fire them off as close to perfectly as the current MIDI stream allows. If you have two events at 1 1 1 1, but on different ports, an AMT interface can fire those events at precisely the same time, which can't happen with a regular (non-timestamped) MIDI stream, as the stream is serial in nature.
Because OSX has time stamping built in to the MIDI server, theoretically all MIDI output operations under OSX should take advantage of this - but at the geeky levels, I haven't been programming with this so I'm not completely up on all the details - it maybe that programs have to be written specifically to take advantage of it.
In any case, it's these reasons why AMT was never supported in Logic under OSX - it was basically redundant.

Unitor 8 Mk2 Advice...

Hi,
Long time Unitor 8Mk2 user, with a few questions:
1. Can the Unitor take advantage of AMT (Active Midi Timing) in OSX, (or was this an OS9 feature only)?
2. Any ideas if the Unitor will be 64 Bit compatible now or in the future, & are the current 2.5 Unitor Drivers compatible with Mountain Lion?
3. I've read the Motu Midi Express is a lot tighter than the Unitor 8 - any Motu users care to chime in. (I know the Motus are USB2, compared to the Unitors USB1, but if you've a lot of USB2 connected, this could possibly negate any USB speed advantage - especially as the Unitor has it's own power supply).
4. I've also read that PCI-e audio cards (with a midi connection) are the tightest midi solution of all. The audio side would be redundant, as I'm already using Apogees, but could I run such a card alongside a Unitor?
All of the above might seem like overkill, but midi is very important to me - particularly for syncing my MPC3000. (I also have a lot hardware synths).
Any advice would greatly appreciated...
Thanks!

CoreAudio has always been using AMT on OSX. And it's not just about daisy-chained devices, a single device can already have significant delays between the channels.
Unlike audio, midi is not locked to a clock source but simply transmitted when available. The time stamped processing of AMT (or other similar systems) introduces a clock that makes sure that processing buffer granulation in audio hosts or scheduler time slices don't create timing jitter.
This is why midi timestamping is essential for all modern DAW midi use. The default CoreMidi compliant USB driver even supports time stamping. But it's not realized in hardware but at a low granularity kernel level directly before the data goes out over USB.
So these days midi timing is not as good as it could be, but time stamping is highly relevant for getting good results, *because* of the issues introduced by other parts of the system.

Does Emagic's AMT (Active Midi Transmission) work with Logic 8?

Is Logic 8 able to utilize Emagic's AMT (Active Midi Transmission) technology as used by it's Unitor 8 & AMT8 midi interfaces? (Similar to Digidesign's Midi Time-Stamping)

it was shown before( as unitor 8 though) but not anymore.
Ok, so it's not installed, and your computer doesn't know about it.
rescan midi doesn't find anything more,
No it won't. OSX can only communicate with an interface through a driver. No driver, no interface.
read somewhere that AMT 8 is not compatible with logic pro, which is odd.
Absolutely incorrect. And mine is working fine with all Logic versions, thank you very much!
Ok, trash you MIDI driver, which should be at:
/Library/Audio/MIDI Drivers/ EmagicUSBMIDIDriver.plugin
Also trash
/Users/you*/Library/Preferences/ByHost/com.apple.MIDI.
/Users/you/Library/Preferences/com.apple.audio.AudioMIDISetup.plist
Reboot. Reinstall the Emagic MIDI drivers from your Logic or GB installer. Reboot.
Check the AMT now shows up in the Audio MIDI Setup utility. If it does, you should be good to go.
Edit: Oh, before you do all that, check that the USB cable hasn't just fallen out..!

Macbook Air 2012: intermittent, random freezes of trackpad and keyboard lasting a few seconds each

There have been a few other people to have reported this problem, but there has been no consistent solution for me on my Macbook Air 13" 2012, running 10.8.4.
What happens is this: while typing, the built-in keyboard and trackpad will suddenly lock up at the same time, randomly, intermittently, and for just a few seconds before returning to normal. This has been true through all the updates of 10.8.x since I bought the system last year.
During the freeze, one of the three behaviors occurs:
1) both keyboard and trackpad are completely unresponsive
2) both keyboard and trackpad get really slow, with high latency. Keys pressed show up much later or have to be pressed several times before registering. Trackpad is jumpy if it moves at all.
3) key gets stuck, sometimes the BACKSPACE key, which usually results in several dozen emails getting deleted or entire paragraphs, or rows and rows of the same stuck key. Pressing other keys does nothing.
I've spoken online with various other people who have the same problem and confirmed that the built-in keyboard and trackpad seem to be joined together whenever this problem strikes. You never see one freeze without the other also freezing.
Also, these commonly-recommended solutions don't work:
a) Reset PRAM. Done this many times. Does nothing.
b) Bring it in to Apple. Did this too. They replaced the keyboard and trackpad but the problem remains.
c) Clearing caches in safe mode. No improvement.
d) Removing "com.google.keystone.deamon.plist" and "com.google.keystone.agent.plist" doesn't seem to work either, even though the errors and behavior are exactly the same for me as for george.e.gonzalez in this thread: https://discussions.apple.com/message/19702976#19702976
These files do come back, though, thanks to Google Software Update. The keystone software appears to be part of Google Chrome, although I cannot confirm this.
e) I DO have Google Android File Transfer installed like one other person reported; they said uninstalling it fixed the problem. Unfortunately, that has not worked for me. Also, Android File Transfer is installed (same version 1.0.50.2266, same Mac OS 10.8.4) on an older 2008 Macbook, and it works fine, which points to something on just this Macbook Air as being the cause.
f) I don't use the Radio Silence firewall app--can't remove it.
g) I don't have the telldus device or whatever it is, so I don't have the "com.telldus.service.plist" to remove.
h) Completely clearing out /Library/LaunchAgents, /Library/LaunchDaemons, and /Library/StartupItems doesn't do anything.
i) Repairing permissions or repairing the volume does nothing.
j) Reinstalling the OS fresh does nothing.
k) I don't have an external trackpad, mouse, or keyboard for testing while the freezing happens, but the machine itself seems to be working, just not the built-in input devices, which are on the same USB bus.
l) Pressing ESC does not stop the key stuck situation, as it does for some people.
It feels to me like a hardware problem, not an OS problem, and it feels like a USB bus issue. I have noticed that when I insert USB flash drives, I get the same lock-up for a few seconds, something which my other Macs don't do.
I've also noticed various USB errors in the Console around the same time (same as george.e.gonzalez):
7/26/13 1:20:04.000 AM kernel[0]: AppleUSBMultitouchDriver::_deviceGetReport - DeviceRequest for reportID 0x0 returned with result 0xe000404f - retrying
7/26/13 1:20:05.000 AM kernel[0]: USBF: 844075.636 AppleUSBEHCI[0xffffff80157f1000]::Found a transaction which hasn't moved in 5 seconds on bus 0x1a, timing out! (Addr: 2, EP: 0)
But I'm not able to precisely correlate these errors to the pause.
Is anybody else having this problem that can shed more light on it than these other suggested repairs? This has been frustrating for quite a while, but I've had the stuck BACKSPACE key delete hundreds of emails on a webmail platform that I was unable to recover using Undo and out of the trash, and that's just no longer tolerable...
Thank you, thank you, thank you, if anyone can help me fix this!

Hi, Dan--
Nope, none of those four... I do have Dropbox but never installed it on this machine. The other three are services I've never signed up for.
I am basically using these apps up-front:
Mail.app, Safari, Notes, Terminal, maybe LibreOffice 4.0.x, maybe Sublime Text 2, Console.
And the freezes happen about twice a day, usually when I'm in Mail or Terminal, but that's because those are the ones where I'm typing the most and can see immediately when the freezes happen. It could be happening even more frequently while I'm browsing, but I might not know it because I'm merely reading what's on the screen.
This is a list from Activity Monitor of what I'm using right now, which is very typical of what I use all day:

IMac doesn't recognise the internal hard disk (intermittent)

Hi, I was wondering if anyone could give me an advice on this problem.
Background: A few days ago my iMac (20-inch MA877LL) would not boot up, it would sit on the gray screen with the wheel spinning for ever. I thought the OS might have got corrupted so I tried to re-install Snow Leopard from the CD. Installation fails with a message like 'the content of HD can not be changed'. I then went to Disk Utilities trying to repair the disk but had no luck with the repair so I decided to format the disk. I managed to get into my hard disk using the cmd R key combination at power up and backed up my essential files onto a external hard disk. I formatted/erase the hard disk (zeroed out) and tried to reinstall the Snow Leopard again. The installation failed again. Rebooted the system again and tried to re instal again but this time I got as far as the 'select the disk where you want to install Mac OS' but my Hard Disk is not listed, it's a blank list! Rebooted the maching again, tried the installation, this time it sees the hard disk but the installation fails again.
I have tried to change the boot source by hodling the 'alt' key down at power up, but I am only given the option of the CD drive with installation disk as the boot source i.e. no Har Disk. It appears that the Hard Disk is intermittently recognised and hence my problem with booting the maching when the problem started.
I am happy to purchase an internal disk to replace the existing one, but I have a feeling the actual Disk it's OK, after all I managed to access my data to back up and then format it with no problem. I just think there's a problem somewhere that intemittently doesn't recognise the Hard Disk.
Any suggestions will be much appreciated.

You need to have the hard drive replaced. The one that is currently installed has failed.

Intermittent AD Authentication failures in ISE 1.2

Starting today I was getting intermittent authentication failures in ISE. It would say that the user was not found in the selected identity store. The account is there though. At one point I ran a authetication test from the external identity source menu and I got a failure and then the next time a pass. I have no idea why this is happening. I just updated to ISE 1.2 the other day. I'm also seeing what looks like a high level of latency on both of my PSN's. Is this normal? Any ideas?
Thanks
Jef

Interesting. I have one location that is not having this problem at all. The other is having it somewhat frequently. The PSN's for each location are tied to the local AD servers. I have not had this until we started getting 300-380 PC's connecting. We are a school so we are slowly getting started. It's real random. One user will work then another time they won't. Happens with admin and user. I have notices that with this new version of ISE it is complaining that it is getting accounting updates from the NAS too often, but I have not looked into this because I just installed 1.2 about 3-4 days ago and haven't had time to look into it.
When you say Multicast to you AD...how did you check that? We do use multicast.

Adobe Media Encoder - AMT Subsystem Error

X201 Fan Error when ME / AMT turned off

Well. upon further investigation I decided to deem intel AMT a security risk, as I read through countless intel docs.
So entered the config of it and set it to disabled.
Now having done this, the laptop reboots and works as usual EXCEPT the fan does not work and the device gets really hot.
Then I wanted to check in BIOS config for any Fan settings to see, when I enter "Configuration" submenu the biosmenu freezes until the laptop is powered off manually.
I tested it a few times, tested other settings that seemed to be able to have an impact on that situation to no avail.
As soon as I turned ME/AMT back on the fan works again and the config menu in bios does not freeze.
It has the latest bios and ME Firmware from the downloads page.
How can I disable ME without having the thing toast itself to death?

Add to your code following statement
set_item_property( 'EFIS_EMAIL_QUEUE.SELECTTODELETE', UPDATE_ALLOWED, PROPERTY_TRUE );
and hopefully that should take care of your problem.

After updating to windows 8.1 my wire less internet connection is getting disconnected intermittently

Classified junk mail intermittently not moving to junk folder

Hello,
I am running Thunderbird 31.3.0 and all of a sudden the junk mail (which is classified and marked) is not being moved to the junk mail folder intermittently on some of the IMAP accounts setup on Thunderbird.
Again, this problem only intermittently occurs but it seems to happen on the same couple of email accounts. The junk mail is marked and stays in the inbox but does not automatically move to the junk folder. If I unmark one in the inbox and remark it - it moves automatically. if I restart Thunderbird, all newly received junk moves as expected for a time until the problem intermittently start occurring again.

One last thing to try:
