New midi trouble.. device or my computer?

i recently got a plug and play midi device (alesis controlpad usb/percussion controller) that is not recognized by my macbook. ive tried all of the troubleshooting provided by alesis and what i could find online, and it seems almost nobody else online is having problems getting it to work (maybe some problems afterwards, but i cant even get it to work!). all other midi controllers i have work completely fine and confusion free. what could be wrong? ive heard something about alesis devices not being able to work on 64-bit OS's, but anyone who regularly updates their software probably has a 64-bit os, and theres not much online about problems with that. ive been sitting here trying for about 6 hours now and have literally come up with nothing. ANY and ALL help would be much appreciated.

Your psu of course does not deliver 36A on +12v. You can't add the 12v lanes. The 18A listed means one rail can be stressed up to 18A but not both simultanously. That is a common mistake people make with split rail psus. It is quite hard to check what it indeed delivers on +12v as it lists a combinded power across both +12v and +3.3v and 5v not +12v alone. As it is an older unit powering your 4870 (requiring 32A and a 500W PSU minimum) most likely stressed it to the max and made it age quickly. Quite possible it is slowly dying. Replacing the psu with a quality single rail psu like Corsair CX600 is recommended.
But I'm using the Radeon 4870 again and I can play for example Battkefield 3 for hours without any problem, and it's overclocked... So why can't I play with my new gtx 660 if it uses less power? I think it has no sense...

I have a family of seven. Five of us all have Apple Ipods or Iphones. Everytime there is a new update for itunes or any of us try to plug our devices into the computer to hook up to itunes we all have problems or it won't let us!...It's getting to the point that we don't want to continue spending hundreds of dollars on Apple products that keep giving us problems. How can this problem be fixed???!!!

What is the problem? We cant help if you dont tell us what the problem is.
Do you get an error message? Do you plug the devices in and nothing happens? Is content not syncing?
Can you elaborate more please?

You did install the latest iTunes (10.5) right? If the problem was that iTunes does not see the iPod try:
iPhone, iPad, or iPod touch: Device not recognized in iTunes for Windows
or
iPhone, iPad, iPod touch: Device not recognized in iTunes for Mac OS X

With brand new iphone 4s when plugging into computer itunes shows a blank page with an apple logo in top left and a small lock in the top right. right clicking iphone under devices shows only eject.

I am having trouble activating my new version of Lightroom on one computer where it says it has been fully installed and it is stuck on 90% on my laptop. I tried phoning the helpline but was told the number dialled was incorrect but it is the one given on the Adobe help page. So what is the correct tel no for support?

Hi Dalegu219,
Thanks for visiting Apple Support Communities.
If your iTunes library is on an external hard drive, but iTunes is not recognizing the library, first make sure the right library is selected.
You can use these steps to make sure iTunes is opening the library on your external drive:
If iTunes is running, quit iTunes.
If you're using Windows, hold down the Shift key and from the Start menu, choose All Programs > iTunes > iTunes.
If you're using a Mac, open iTunes and immediately hold down the Option key.
You should see one of these screens:
Pick Choose Library and locate the library on your external hard drive.
From:
iTunes: How to open an alternate iTunes Library file or create a new one - Apple Support
If the right library is selected, but you do not see your songs, try re-creating the library using the instructions found here:
iTunes: How to re-create your iTunes library and playlists - Apple Support
Best Regards,
Jeremy

How To Get A New Midi Keyboard Working On Mac 5G

Hello
i have a new midi keyboard ( Yamaha mx61 ) and an old mac 5g. Iv used a midi drum kit fine ( Yamaha DTX ) just plug in and play with garage ban. However, the keyboard want be found. The USB ( small ) from the keyboard to the USB to the computer , same as the drums and it's pick up as a standard typing keyboard.
Iv tried using the discs given but they won't work as this mac is running on10.4.11. Is there anyway to get it to work in garage band or is this to do with my mac being old.
thanks

Buying an Install Disc is the only way, it an Upgrade rather than an Update in strict terms.
10.4.x to 10.4.11 is an update, 10.4.x to 10.5.x is an upgrade.
Leopard requirements/10.5.x...
    * Mac computer with an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor

    * DVD drive for installation
    * 9GB of available disk space (I say 30GB at least)

HT1495 how can i sync aps on multiple devices on one computer

Trying to use multiple devices on same computer but don't want the devices to have all the same aps. how can i seperate that without having to check the aps i want each time a sync?

Assuming the photos are in an iPhoto Library on the Air and you want to import them into your iPhoto Library on your Powermac there is an application that can copy all photos in the Air library that are not in your Powermac library into your Powermac library. However, no keywords or other metadeata willl be brought over with them and they will come over in a new event each time you run it. Take a look at: Sync iPhoto libraries | SyncPhotos (formerly iPhotoSync) | Haystack Software.
There's another application, iPhoto Library Manager, that will let you copy events or albums from the Air library to the Powermac library. However, you will have to select the events/albums you want to copy. It's not automatic. This method will copy keywords and other metadata along with the photos.

i-devices are intended to by synced with iTunes (iTunes --> device), not transfer things to iTunes. For transferring songs from i-device to computer see commercial software utilities (with the exception of iTunes purchases). Examples (check the web for others; this is not an exhaustive listing):

My iphone5 no longer shows up as a device on my computer when I plug it in to a USB port on my laptop. It does not appear in iTunes as connected, either. It does show that it is connected and charging on the phone itself. This is a new problem. It used to work just fine.

Had 3G, moved to 3GS. Backed up 3G and restored 3GS from backup with no problem. When I want to add songs, I get itunes message that the new iphone is synced to another computer and now wants to erase everything. How can I add music?

Had 3G, moved to 3GS. Backed up 3G and restored 3GS from backup with no problem on a Dell computer. But now when I want to add songs, I get itunes message of death that the new iphone is synced to another computer and now wants to erase everything. How can I add music without erasing everything on my new iphone?

Yes, I was aware of this but the phrase "Any items imported from audio CDs or acquired from other sources will not copy from your device to the iTunes library." is what worries me. Will this eliminate my Notes, Calendar Events, etc or will it apply mostly just to the music?

How do I select a midi input device and record midi?

I have several midi input devices connected to my computer. I use them regularly with Digital Performer. I am trying to record a single midi track in Garage Band using an Oxygen 8 keyboard. In the preferences GB says that it sees 7 midi devices. How do I route midi with Garage Band and how do I tell Garage band which midi device to record from? When I create a midi track (well...I think that it is a midi track) and I try to record I do not see any midi notes being recorded.
Searching the help file for midi provided surprisingly little information. I am sure that this is simple stuff...perhaps so simple that I am missing something obvious.

Yes, if the controller sends the right MIDI messages
What do you mean by "the right midi messages"?
I have a virtual instrument (with for example) a delay effect knob. I would like to turn a knob on my midi controller and adjust the delay in the virtual instrument (as I can in just about any other sequencer). Can GarageBand do this, if so, how?

You need to copy everything form your old computer, or your backup copy of your old computer to your new one.
The iphone is not a storage/backup device. it simply mirrors the selected content of the computer to which it is synced.

Best way to transfer from mid 2012 macbook pro retina to new mid 2014 macbook pro

I'm updating to a new 2014 macbook pro. am i better off using a migration assistant from one to another, or restoring from Time Machine (with ethernet to thunderbolt adapter)? Or some other method?
thanks,
ptkmac

I have used the Setup Assistant during setup of OS X and I would use a current Time Machine back up to point to during Setup Assistant. I have also manually copied data and apps over from another Mac while on my network. Both take some time and both were equally successful.
So, you have a choice after backing up your current Mac:
Have both Macs on your network, run setup on your new Mac and afterwards manually copy files from the old to the new Mac.
Run setup on your new Mac and use the Setup Assistant to migrate from a Time Machine back up all your user accounts, data and settings.
Question on a similar line except I wanted to partition the drive that came on the new Mid 2014 MBPro (2.8 GHz, 1 TB SSD, 16 GB RAM). Migrating from the old computer b/u seems pretty straight forward, but once the drive that come with the new MBPro is partitioned an install of OS X needs to be done. Here's what I did, I installed the Mavericks I had purchased from the App Store when it came out. Now, from reading here in the Communities, some have indicated the shipped Mavericks version is not the same as the App Store version. Now that the shipped Mavericks is history (after the partitioning) should I try somehow to restore that from the Recovery HD/process? Or ???
This isn't my first rodeo, so I just went full speed ahead and did the partitioning and copied the former MBPro (early 2011) disk created by Carbon Copy Cloner over to the new boot partition. It was suggested that an Erase and Install OS X could be done, but I don't see how that would bring the shipped Mavericks version for this new MBPro, unless the Recovery HD suite of utilities would go and grab that from Apple via Internet; which would be fairly lengthy since it would be via Internet connection.
I'll back up a bit here for a second... I"m not experiencing any problems (kernel panics, etc.) but not sure if the system now is as it should be. Hindsight being what it is I should have made a CCC copy of the shipped volume of Mavericks; if this is an issue.
The system seems to be running fine, and some of my "issues" (for lack of a better term) could be just the way the new Mid 2014 MBPro is handling things - like memory allocation (i.e. using close to the 16 GB most of the time) and kernel_task using 1 GB of memory - more at times). Possibly if I wasn't a regular watcher of Activity Monitor I would just be plodding along, since the system seems to be working fine. Occasionally some apps or their processes take a longer than I feel is what should be normal to do, hence looking at the Activity Monitor to see what is going on.
Sorry for the long ramble. Trying to see if I really have a problem that would necessitate a reinstall of Mavericks via Recovery HD; which could take up some valuable computer work time (which I'm also using posting here <grin>).
Thanks in advance for any ideas, suggesting, etc. Also, to the person who posted to my other question on this another thanks for those suggestions. None of which I've done - yet.
Take care all - and thank you again for all the great minds who make these Community Boards work.

I want to mirror an iOS device to my computer for demonstration and training purposes. I cannot use Airserver as my company VPN does not allow the connection. Is there a hardware solution instead?

Shoeb, hi.
Thanks for replying and apologies for my tardiness in responding. I have just completed a re-creation of my web page using CSS/HTML rather than XML/XSLT and now I find that when saving in MHT format the watermark/background image is saved, which is nice, but trying to save it as 'webpage complete' under 'save as' in the browser still does not work. (For those who are new to Firefox, MHT files are not supported by the browser, but using the FF extention UnMHT one can open such files and save web documents as MHT files, meaning no accompanying folder is required to properly view the file.)
