What you need is an USB recording interface with a microphone preamp (like M-Audio Fast Track), they usually cost $100 and up.
Try using the MIDI audio interface. There are also MIDI USB that you can just connect from your Synthesizer to your computer.Hope this help.
A USB Mixer is an audio mixer with a built-in USB audio interface. It is sometime better than a stand-alone interface since you can plug in more microphones and instruments at once. They usually get mixed to a stereo mix, so it isn't possible with most of these mixers to track a drum kit or other instrument that requires a lot of mics and individual tracks. You can't use a USB mixer with Pro Tools 8. Pro Tools LE 8 only works with the MBox and the Digi 002/003 hardware from Avid. Pro Tools M-Powered 8 works with M-Audio USB and Firewire audio interfaces. If you want to run Pro Tools 9 (the current version), you can use any USB mixer that has ASIO (PC) or Core Audio (Mac) drivers.
You don't need a mixer. You will need an audio interface (either USB or Firewire) that has phantom power, that is, 48 volt power to power this condener microphone. With the interface connected, you can use this microphone with Garageband or any other recording software that support CoreAudio hardware.
An XLR to USB cable has a converter in it. It isn't just a cable. An audio interface can be used to allow you to use any dynamic microphone or instrument and connect it to the USB or Firewire interface with an XLR cable.
1) Microphone to XLR-cable to Mixer XLR-input 2) Mixer main out or tape out to interface with RCA cable 3) Interface to computer with USB cable 4) You need to install drivers for the interface and you also need a recording software
You must have an interface which is connected to your Mac. A mixer will connected to the interface from the direct outs - normally up to 16 channel depending on the inputs of the interface). or You can purchase a mixer with usb or firewire capabilities such as a phonics helix or Allen and heath zed series.
The American Audio M-52 USB Mixer/Sound Card is best for running a mixer. anonymous@oola.com
The Xenyx 1622FX comes with an external USB audio interface that connects via RCA cables to the mixer's tape in/out jacks. The mix recorded to the computer will be a stereo stream of the main mix output, so all the instruments will be combined together. Beheringer does not (yet) sell a mixer with multi-channel USB or Firewire audio output.
You will need an audio interface with an XLR input and phantom power to connect the MXL 990 microphone. The Steinberg CI-series of USB interfaces are perfect for this, and are designed for Cubase.
Very few powered mixers have a USB audio connection, but you can connect the line output out of almost any mixer to the inputs on the Mac to record with GarageBand.
To connect a crystalline microphone, first locate the input port on your recording device (such as a computer or audio interface). Then, use a compatible cable to connect the microphone's output to the input port. You may need an adapter or interface depending on the microphone's connection type (e.g., XLR, USB, or 3.5mm).
