Now that you've decided on your audio interface, you'll need recording software. You simply cannot do without some of that. In expert speak, recording software is known as audio sequencer or DAW software (DAW = digital audio workstation), and it is a piece of software that allows you to record, cut, arrange and mix sound. You can record several tracks simultaneously or successively (overdubbing). The various tracks can be processed in compressors and/or equalisers. Anything people used to do on mixing consoles, tape machines and effects processors you can nowadays do on your computer, a convenient "in the box" way of working. Many contemporary ways of working with recordings are only possible thanks to modern computer recording technology. Apart from straightforward audio recording, you can also compose and arrange music based on MIDI with typical sequencers.
In the following, we will give you a short overview of current DAW software:
Often an audio interface you buy will come with so-called "lite" versions of, for example, Steinberg Cubase or Ableton Live. These free-of-charge "goodies" are significantly slimmed down compared to the full versions; they are intended mainly to make you curious for more. Still, you can often do quite a lot with these "lite" versions - they are definitely enough to allow you a fair bit of experimentation if you don't have a lot of experience. Once you really get into home recording, however, you'll probably quickly reach a point where you want a more extensive piece of software.
If you use your sequencer software for MIDI-based arranging, too, you'll need a wide variety of virtual instruments. These are integrated as so-called plug-ins. Plug-ins are basically small sub-programmes that are added to the sequencer software. Most sequencer software comes with some plug-ins. But if you're after really top-quality instrument sound, you'll have to consider buying some plug-ins from specialist software companies. Some popular ones are Native Instruments, Best Service, East West, and IK Multimedia - and there are many more.
