The Toolbar Module enables you to custom-configure the display, which simulates that of a standard rack-style set of stereo components.

The Mixer Module makes it possible to set volume levels on all of the recording and playback devices, specify logical connections for recording different input sound sources, mute or unmute individual playback devices, adjust the bass and treble levels of the output signal, and turn on or off several digital filtering functions including loudness equalization and stereo enhancement on soundcards that support these features.

The Midi Module lets you play a selection of midi (.MID) files, either one at a time, or in a continuous loop.

Similarly, the CD Player Module lets you program a CD-ROM player to play selected tracks. It "remembers" each CD you play, so that when you put in a CD to play, you can select a previously stored set of favorite tracks to play.

The Wave Player Module lets you record and play standard PCM wave (.WAV) digital audio files. You can convert .wav files to .mp3 files with this module.

The MP3 Module lets you record and play MP3 files, download MP3 files from the Internet, as well as edit ID3 Tags. You can convert .mp3 files to .wav files with this module. All four of these playback modules provide a very handy means to set up, save, and retrieve Playlists, that is, a user-specified list of files that you wish to play, which can be in any sequence.

All of these modules are very intuitively arranged and simple to use.
