Help with usb Midi controller on brand new machine! Please!!

I just unboxed my macbook pro 13" non-retina and updated to 10.9.1, installed a few of my apps, etc. I'm having a meltdown over my midi-controller not being recognized. It is a Roland A-49 USB Midi Keyboard controller that is not powering on. It runs off bus power just fine in my older 15" MBP and also from my '12 Mac Mini. When I pull up the system profiler, under USB it reads to me:
How can I get this working properly?

Hi there, been a viewer of the discussions here for a while & felt compelled to finally sign up to hopefully offer some help with this problem as I had exactly the same when I first got Logic Pro.
The problem is more to do with the sound setup than the controller keyboard as logic is sensing midi data as you have seen in the transport.
I would suggest firstly (Hopefully Pro & Express are the same in these respects) clicking on the Logic Express tab in the top left, then Preferences, then Audio.
In the box that appears select the Drivers tab. Then make sure that the Core Audio check box is ticked. Under that make sure that you output source is selected (ie your interface if using monitors, or built in Audio if not)
Hopefully this should help.
The simplest to test your sound is by clicking on the Audio tab (3rd or 4th along at top) & opening the Loop Browser, choosing a catagory & draging a sound onto a track.
Remember to click on the track you will be dragging onto to select it & in the Loop Browser Blue loops go onto audio tracks & green onto instrument tracks.
Now with testing the controler keyboard...
Click on an instrument channel, then goto the bottom left of the screen where you will see that channels fader.
Above the fader click on the I/O (you may have to click & hold here) choose either mono or stereo, then choose say the EXS24 & try you keyboard.
Hit * on the numeric keypad & play something, then hit space to stop & you will have your 1st region.
I hope this helps with you problem, Logic can be confusing at times but is worth sticking with.
Good luck

Hi
does anyone know how to fix the message on my iMac:
"Because a USB device was drawing too much power from your computer, one or more of your USB devices have been disabled."
This is a brand new machine and did not have anything attached to the USB ports"
Thanks for any help

If you are getting that message on a brand new Mac with nothing connected to the USB ports, take it back. It is broken.

If you look at the feed, and look at the entry 'The end to an exciting field season in Aulavik National Park' you will see the line:
<pubDateFri, 29 Jul 2011 04:00:00 GMT</pubDate>
You have not closed the 'pubdate' tag - there should be a '>' as the 9th character. Because the tag has been left open, it invalidates everything which follows it, and thus the entire feed. iTunes therefore cannot read it, which is why the Store has not updated. Add the '>' and republish, and all should be well.
It's always worth checking your feed by subscribing manually, from the 'Advanced' menu, or by clicking the 'subscribe free' button on the Store page (both do the same thing) - if you can subscribe to the feed it should be OK.

Hi,
To access the MIDI ports you will need to call the Windows SDK. To send MIDI commands is relatively easy, here is an example that shows you how to send data to a MIDI controller or keyboard.
As far as input goes, this is the hard part. There are a series of functions that you need to call to open up the device, set some buffers and and possibly a callback to get notifications on the incoming data.
Reading MIDI data will not be an easy task, your best bet will be to implement this in a DLL and call that DLL in LabVIEW, there should be some code available o the web.
= "http://msdn.microsoft.com/library/default.asp?url=/library/en-us/multimed/htm/_win32_multimedia_... is a link to the Windows multimedia functions that you could use for MIDI input.
Let me know if you have any further questions.

Do you have a wired USB mouse to try?
It seems to me that the drivers from the WIFI mouse is not of the correct version for the OS you are running on.
You may want to google for the correct drivers as well.
I have tried a wired usb mouse and that wont work either :(
There are only 1 set of drivers for the wifi mouse I have, checked on the manufactures website and the driver version is the exact same one as I have on disk. The mouse worked on my other pc with the exact OS
A ps2 wireless mouse works but that mouse has no range :(

Hi - I hope this helps. The problem may be hardware related in which case I can't help, but if not, try this.
Right click and delete both of the yellow mouse HID drivers in device manager. Then do a normal shutdown and Restart with the keyboard using Ctrl-Alt-Del to bring up Windows Task Manager.
This should force the system to reinstall drivers when it next boots.
You may find that a simple Scan for Hardware Changes also works after you have deleted the yellow drivers.
Another trick is to try the mouse in other USB ports - sometimes the system just gets confused and sets the device to a particular port. If it is put in another port it often can't find the device.
Good Luck
I have tried the wireless mouse in every usb port, also uninstalling them in device manager - all had no effect :(

USB MIDI Controller no longer working after Logic 8 upgrade

Hello, my M-Audio O2 USB MIDI Controller worked brilliantly with Logic Pro 7 after simply plugging it in. I never needed to install any drivers or do any setup. Now, after upgrading to Logic Pro 8 it isn't recognized and does not work. Does anyone know what's going on and can anyone please give me some advice on how to fix this problem? Thanks

Go to Logic-Pro beside the Apple Logo at the top of your screen to the Left,
then Preference,
then scroll to Control-Surface settings,
now select set-up
From there delete and then reinstall your control-Surface, do it manually as the Scan doesn't work all the time,

USB MIDI CONTROLLER- LOGIC PRO 7- I CAN SEE THE LIGHTS BUT NO SOUND OUT?

I just got logic pro 7.2 so i am very green, garage band automatically recognizes the usb midi controller and i can hear it,
in logic it recognizes it i can see the lights for sound levels but no sound is coming out, ive been trying to figure this out.

Heck, if loneliness is your thing... more power to ya!
now why cant i hear the midi
MIDI doesn't make a sound. You either need to assign a software instument to it or use an external device, all depending on the track you chose. If you, perhaps elaborate a little more as to what you did (typing with your caps lock released), there's a better chance of getting your problem solved. If you're hearing your recorded guitar, then there's a chance you selected the wrong type of track to record to as far as MIDI tracks go (there is a difference in Logic).

Dirty environment found on brand new machines

Hi
I'm doing a deployment purely from USB onto a brand new machine and after the first reboot following the OS installing I get an error about dirty enviroment found. The google results all point to this being due to files left over from a previous deployment
but this is happening to brand new machines.
The USB drive is the first boot device and I'm trying to install Windows 8.1 using MDT 2013.
If I dont make the USB first boot device, after the OS install it just boots into Windows and fails to carry on.
Any suggestions?
Thanks
Chris

I'm not 100% sure about what the problem is from your question.
However, as a general rule of thumb... you should never make the USB device the 1st boot device in the BIOS of a computer (For security reasons and others), instead most (good) BIOS/Firmware makers supply the ability to temporarily boot to any device. For
my Dell and HP devices, I press F9, for Lenovo I press the blue THinkVantage button, for my ASUS Motherboard devices, I enter the BIOS via "DEL" and select the boot device there.
IF you change the boot order in MDT, and reboot without changing the boot order back, the BIOS will boot back into WinPE, instead of booting into the OS.
If you are still having problems, remove all the \_SMS* and \MININT folders from the machine and restart.
If you are still having problems, copy the newest bdd.log file from the machine (search everywhere), and copy to a public site like SkyDrive, and share the link.

The problem doesn't lie with your feed, although it does contain an error - you have given a non-existent sub-category. You need to stick to the categories and sub-categories listed here:
http://www.apple.com/itunes/podcasts/specs.html#categories
Subscribing to your feed from the iTunes Store page work as such, but the episodes throw up an error message. The problem lies with your episode media files: you are trying to stream them. Pasting the URL into a browser produces a download (where it should play the file) of a small file which does not play and in fact is a text file containing (in the case of ep.2) this:
[Reference]
Ref1=http://stream.riverratdoc.com/RiverratDoc/episode2.mp3?MSWMExt=.asf
Ref2=http://70.33.177.247:80/RiverratDoc/episode2.mp3?MSWMExt=.asf
You must provide a direct link to the actual mp3 file. Streaming won't work. The test is that if you paste the URL of the media file (as given in the feed) into the address bar of a browser it should play the file.

Big Problem with brand new iPod please help ME!!

Hi, I just today got a brand new iPod. I pluged it into my computer and put on about 700 songs immediatly. Then, I tried to put video on my iPod. It said it would not do this because it's not the right type of iPod. But it is a 5th Gen. iPod and it can play video. Anyway, I installed the latest iPod updater. Now, it says to install the new iTunes 6.01. So I tried but it says my disk is full. It is not full. Also, do I have to keep my previous "iPod for windows" files that are occupying space on my disk?

Kenny,
If you can back your songs up, and you have not rated a slew of them already, it might be a good idea to uninstall iTunes, then reinstall it and use the ipod updater to wipe the iPod. Just make sure you download and install 6.01 before you plug the iPod in. Maybe that will get you past the disk full problem. Just something to try.

USB MIDI controller no longer recognized by mac (not even in System Information).

Hello!
I have an M-Audio Keystation 49e that I have been using with my MBP (early 2008 model) for a few years with absolutely zero problems ever. I recently bought a very generic Chinese MIDI interface ("Sanoxy" brand) to go between my full-size Yamaha and mac so that performances of parts into logic would be on weighted keys and such.
For a while I used both the MIDI interface with the Yamaha and the little 49-key MIDI controller (via USB and also powered by the USB) with no problems. I believe this problem occurred when I tried to use both the MIDI interface and MIDI controller on one USB port using a Targus external number pad (unpowered) that has two USB ports on it (bad idea I'm sure). I did this because my MBP only has two USB ports on it and I was using the other for my audio interface.
I have reset PRAM more than a couple times, reset SMC, cleaned caches (even though this could be done more thouroughly maybe with a recommended program besides Cocktail - trial is expired), even replaced AppleMIDIUSBDriver.plugin from my parents iMac which the MIDI controller still works on. All this and nothing. The keyboard is not recognized as even being plugged into the USB port on System Information even though the lights are on, much less AMS.
Any other information you need I'd be happy to let you know.
Super thanks!

Why does OCR crash with Acrobat XI on a brand new Mac. It happens almost every time on a long document.

Brand new Macbook Pro, running OS X Mavericks. Latest trial version of Acrobat Pro. I need to make lengthy (say 1,000 pages) document searchable. OCR crashes after a couple of hundred pages every time. I get an error like this:
abort() called
terminating with uncaught exception of type IDRS::CIDRSException

I've had a similar problem. I was going to start a new thread but I think I'll just include my problem here.
I am OCRing (if you'll allow me to turn OCR into a verb) a large number of documents. Every once in awhile Acrobat crashes. It gives the message that I've pasted in below. There was some discussion about this in a previous thread, but that concerned Acrobat 9, and an Adobe representative responded to the thread, saying that the problem would be fixed with 9.1. There was talk there of the problem being one of resolution of image, but that possibility seemed to have been ruled out. This problem usually occurs with larger files (greater than, say, 25 GB), and rarely with smaller ones. (I should mention that I'm OCRing Japanese language documents, but this really shouldn't make a difference.)
Other threads about this: Acrobat 9 crashes on OCR and OCR CrashingCan anyone help me with a problem I am having with the current OCR engine crashing, I have a lot of difficul….
If Acrobat simply skipped the problem pages it wouldn't be such a problem, as I'd simply have, say, three or four non-OCR pages in a 500-page document, but that's not the case. Instead it crashes and I then have to go back and actually watch the OCR process, waiting to see which page is the problem so that I can manually skip it. This turns a process that ideally is one my computer does while I cook dinner or do other work into a time-consuming endeavor.
Any help would be greatly appreciated. If I need to post an example of the problem page here I can do so.

USB Midi Controller not recognized by Mac?

hey there
I have just attempted to plug in my trusty Edirol PCR300 to my mac for the first time. It currently works on my PC
I installed the 2.0.0 driver as per instructions on Edirol website, rebooted, plugged in and turned on the device.
The device is recognized in the system profiler (about this mac etc etc Hardware > USB) however it is nowhere to be found on the midi page of the Audio Midi Utility. One would expect it to turn up here when i press Rescan Midi.... and needless to see it's not turning up in Logic and nor is it an input option on the PCR Editor software.
Obviously i've tried turning it off and back on etc etc.
Running the latest Lion, latest Logic and latest Edirol driver on a Macbook Pro i7 with 8GB RAM.
Any help would be appreciated, i've been trying to get this working for 4 hours now!

Hi Guys
I have a PCR connected up here, running OSX.7.3, it works fine:
It does need drivers, as discussed in my earlier post.
The OP's issue is probably down to incorrect driver installation, or possible some conflict with other MIDI drivers. If the OP has not solved the problem, I suggest using the Edirol driver removal software, and then re-installing the drivers.
(Always assuming that the keyboard does work OK on another computer, and that the cable is OK).
