If your keyboard has USB output, just connect that to your computer.
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.
Yes, you need a cable for your keyboard, usually a MIDI.
You need some sort of interface and a computer in between first.
Any keyboard instrument which has a MIDI port should work. If the keyboard / controller doesn't come with drivers and software, then as long as it supports general MIDI standards it should work. I'm assuming you already have some sort of MIDI interface. If not and the keyboard is USB, your mileage may vary but most that are come with a driver and software to enable this.
You can get Cubase from Steinbergs website
With Cubase.
YOu forgot the important part: How do you use WHAT in Cubase
Cubase 5 is no longer sold or produced due to the release of the newer Cubase 6 and Cubase 7. These newer versions of the software retail for $400 each.
A mother keyboard is a basic piano-keyboard interface for use with digital sound composition & recording. It is more basic and less expensive than synthesizers and sequencers, because a mother keyboard doesn't contain all the sounds and recording / sequencing capabilities. Instead, a mother keyboard is used as a dummy input device in conjunction with a digital / virtual computer studio environment such as Cubase. All the samples, sounds, effects and tracks are generated by the computer program rather than in the keyboard itself. The mother keyboard is a blank keyboard which just sends digital signals to the PC, telling the software which notes have been played. If the mother-keyboard keys are weighted / touch-sensitive, it will send that info too, and other sensory pieces of information allowing the software to digitally replicate what the user / musician is telling it. The software then transforms these signals into music.
Cubase is better for the beginner. ProTools is not considered a "home" recording solutions. Try the simpler version of Cubase, Cubase Essentials.
��� Live recording functionality amd workflow is optimised in Cubase ��� Audio editing equivalent to midi manipulation within Cubase ��� Professional scoring capabilities not found within FL ��� Yamaha hardware integration in Cubase especially the professional mixing desk range ��� Cubase has the ability to export in OMF protocol to Pro Tools. FL studio itself can actually be used as a VST plugin within Cubase
Lambda audio/midi interface was made for Cubase LE and is not compatible with Pro Tools. Now with Pro Tools 9 saying it supports any previous interface, I'm not sure. I have not updated from 8 to 9 yet. So if you plan on using pro tools 8 or earlier than no it is not.
