I got one of these for Christmas and at first when I connected the MIDI cables of my keyboard to my macbook pro, it was a bit fidgety but eventually connected. Now when I try, the usb light goes on for a second and then dies. I tried re-connecting everything, restarting my computer and even changed the midi cable, but nothing works. Everytime the computer restarts is the only time it actually recognizes it's there. What could be going on? Is it broken?
I had the same problem -- the following worked for me:
Go into your Audio MIDI Setup application -- there should be an item in the window called "IAC Driver." Double-click it and check the box that says "device is online." If everything else is connected/set up, this should fix the issue.

Does your keyboard have a "MIDI OUT" port? If yes, then
there is a selection to choose between USB or MIDI OUT port.
For my M-AUDIO oxygen 61 (silver), I must press the [Advanced] button then Note F3 on the music keys manual to toggle the MIDI-OUT.
If set to INT, it will not sent via USB. If set to USB it will not send via MIDI-OUT port. To use MIDI-OUT port I need external 12V DC adapter.
There are quite a few ways to do this.The simplest way is to just use the USB port on the keyboard and run that into the computer. If your keyboard has a USB, then you dont need the midi to connect to a computer. You would still use the midi however for other sound modules and items that do have a midi in port however. If you dont have a midi in then you need to get hardware that does as a computer will not have a midi in. There are basic adapters that you can get that just have a midi connector to usb adapter. There are external sound card devices that will do this like the tascam 144. There are also simple devices made my midiman such as the 2x2 midisport that allows you to connect up to 2 midi devices to a computer. The cheapest quickest method if you are just starting out is the midi to usb cable though. Places like walmart, best buy, and radio shack will generally have these. However with making digital music the cheapest is not generally ideal but will get you by in the meantime.If you ever plan on recording audio like vocals or guitar then I would recommend just getting something like the Tascam 144 MK II as it will allow you to input midi, spdif, vocals with phantom power, guitar line in, through it with 24/94 bit conversion, audio drivers, and a bit of software for simple settings configuration. This would be more of an intermediate interface. If you want some pro solutions, then I would recommend going to the pro's at a musician store and talking to them.
Are you connecting to the laptop and using it as a midi controller? You can record midi notes from the keyboard and send them to your laptop via USB using any midi sequencer program (reason, logic, etc). Create a midi track, select the input of that track as your keyboard, then hit record to play some midi notes. To hear what you record, you have to set the output of the midi track to whatever midi sounds or instrunents you have installed on your laptop.
If you are trying to record the actual audio sound the keyboard makes, use an audio program such as cubase, sonar, audacity, pro-tools, and either mic the keyboard, or connect one of the other audio outputs (1/4" TRS) to an audio input on your DAW, and record an audio track that way (as opposed to a midi track).
The keyboard will NOT show up on MY COMPUTER as it does not have memory to record and save MIDI files... It will PLAY them real time as the computer sends the data to the keyboard. You can't transfer and save the files IN the keyboard. Some higher level keyboards do have memory and even hard drives... this one does not. This one will have some built in,that you can play but even those you cannot access as if they were memory.
With the USB cable connected, you should be able to see the device listed in the device manager section of the control panel under system hardware.
I'm not familiar with that particular projector, but I believe I can help you get a couple cables to hook them up.
According to some specs I found * the projector has a VGA connection. Next we need to figure out which MacBook Pro you have. Does it have a silver keyboard or a black keyboard? If the keyboard is silver, you need a "DVI to VGA" cable, at least a metre long. You might want a longer one. If your keyboard is black, your MacBook Pro probably has Mini Displayport. That's a bit more exotic, but I'm sure you'll be able to find a "Mini Displayport to VGA" cable.
You can also get adaptors and then use regular cables.
For audio, I believe they're called 3.5 mm stereo plugs. So you'll neet a 3.5 mm stereo plug to 3.5 mm stereo plug cable. Make sure it will be long enough.
Apple sells both kinds of cables. If you want to save money, you might shop around. I don't know UK stores, so I don't know if I can help much there. I buy my cables at www.monoprice.com, an American site.
