Multiple audio playback units (A,B decks and C,D,E,F,G):
Audio playback unit includes:
- Waveform displays (both full song and zoomable)
- Looping with good adjust options.
- Alter audio file tempo (slowness,faster), pitch (high,low) and sampling rate with several options.
- Adjust file start position by 1/100 second accuracy using jog or waveform.
- Adding bookmarks/store multiple file positions.

Audio file import/song library with:
- Option to select information fields to be displayed.
- Horizontal scrolling (wide text rows).
- Viewing artworks attached to audio files.
- Browse/narrow song lists by different fields (on left,top,right from the list).
- Prelistening option within the song library with waveform option and bookmarks option.
- Browse folders on hard disks directly (File Browser).
- A list of created/edited folders/playlists on the left.
- Supports creating multiple separate audio file libraries.
- Option to have both file library and playlist editing (at left) available at the same time.

Main playlist with:
- Selecting audio files from the library, then playable in Automix mode from the playlist, loads the files to playback units and performs transition (fade-in/fade-out) near the end of audio files.
- Option to save/open playlists to hard disk (with option to include audio files next to the playlist (copy)).

Record audio:
- 6 hours maximum audio record time, then needs to be saved and started again.
- Recorded audio can be saved as a single file or split to multiple files (track marks) with an editor which is shown after the recording has been stopped.
- Quickly load recorded audio back to the software for multiple processing (record and re-edit).

Export audio:
- Similar to record, is not done in realtime, instead, the recording is done as fast as goes,
which may be 2-100x times faster than the song would play.

Batch process audio files from the file lists directly (right-click), with selected tempo/pitch/rate adjusts and any effects set to the effect chains.

-Effect chains:
separate for the audio playback units, main outoput, sampler.
Effect types include:
reverb, delay, filters, flanger, multi-band pitch adjust LFO, dynamics(compressor,expander) and special band gain adjustment (DMBE, could be used while slowing down audio files as an effect).

-Effects may be freely added removed, order of effects may be changed (right-clicking effect-units).

-Presets saving/loading available for reloading created effect parameter settings.

Modest sample playback feature, which allows to crop an audio sample from an existing audio file and
play such conveniently by pressing a button, or with a keyboard shortcuts. Sample can be set as loop with crossfade. Created selection of samples with settings (Samples A1-8,B1-8...) may be saved to hard disk and reloaded later.

-Tap BPM (beats per minute) of audio files manually using included tool, or use the included automatic BPM detection, which is usable for many rhythmic audio materials (can be turned off).

Common manual mixer features:
Crossfader for decks A/B left/right, and also for other decks within there, such as Decks A/B Left and Deck C right... Channel level/gain adjusts, EQs, LP/HP filter, headphone listen toggle.

-Dynamics limiter for the main output which mostly unnoticeably reduces/amplifies audio files dynamically when needed, preventing distortion and also balances audio output levels (can be turned off).

-Multiband limiter is also available, which is processed separately for low,mid,high bands, then bass sounds do not cause as much limiting effect on middle or other frequencies. Multiband limiter has several adjustment knobs to alter: from soft limiting to serious compression...
Each of the limiters: low, mid, high includes adjusting equalizing, and adding effects such as delay or reverb.

-Creating precise transitions from one particular file to another particular audio file (when set to Automix mode), including setting audio file offset relative to the other audio file, adjusting lengths of fade-in and fade-out (crossfades), the editor has zoomable scrollable view, with option to mute either of the audio files for testing temporarily, shorter audio samples may be attached to play during the transition of the two main audio files, with editor, which includes setting offset where to start sample, length of sample, adding effects, equalizing samples if needed.

Effects may be added separately to either of the two audio files in the transition: for the audio file faded out, and audio file fading in, with effects includes dynamic parameter adjusts, where the effect parameters may be set to vary during the transition precisely.

The software includes good amount of documentation with image screenshot clips within the text,
documentation is in HTML format.

Does not have a skin-system, but the user interface can be altered y, many of the image files are editable, and includes built-in adjust for differente about twenty or so colors used (song lists colours, display colours, background colors...)

Recorded audio can be saved if the software was not properly closed/power failure. Also includes common playlist/other background-autosave feature which asks to restore unsaved if the software was not poroperly closed.

Includes a vast list of the software's functionality/features for use with hardware/MIDI(USB) controllers, which allows to set different features of the software to be accessible from physical controller devices, with buttons, sliders, knobs and similar, although the support is not very modern, such as many jog wheels or other more non-common control types likely won't work, though has a limited user editable control type definition option.

hardware controller setup editor has backup/save/load setup option,mulitple setups creation, and multiple hardware controllers may be used simultaneously. A same button or slider/knob may be set to multiple functions: by a button which then selects a function for the slider, knob until selected to a different.

Software does bot have much pre-created keyboard shortcuts, but the editor has vast lists of functions to set as shortcuts, with right-click options for some of the functions.

Creating multiple groups of keyboard shortcuts, which may then be switched from the menus, a same key on the keyboard then may be set to different functions, as selected from the menus.

Dual audio output: speaker/main and headphone audio, for unheard adjustments which require pre-listening, without interrupting speaker output. (Optional to use).
Which may be sued as:
Four(4) channel audio-interface/sound-card
or with two(2) separate sound-cards (such as with built-in)
or with a stereo output by creating a mono channel 2x output.

Includes option for microphone input, audio mic options has latency options to find proper latency/delay for microphone, which is usually not immediate but.. not very serious delay with microphone input/output.

Audio options includes double buffering, with option to select, buffer length from 200 ms to 1.5 second, while creating such delay between playing "play" and hearing audio output, prevents audio interruptions.

The software is described as acceptably efficient, isn't very efficient, much or all of the software would be usable son modern computers, so is about having twenty or such effects added to effect chains, or many audio files with time pitch adjustments processed in realtime, simultaneously, likelyhood of experiencing audio interruptions.

In the mode "Automix" where audio files are played from playlist one after another with creating transitions between audio files, the program uses correlation calculation to improve smoothness of transition, although isn't usually beat precise or similar. The feature may be turned off if not needed.

Loudness is obtained from opened audio file data, then the amount of loudness is scaled, resulting in less audio level variation with different material, this may be turned-off if needed. (Should be combined with compression for serious level-balance, such as low-bands/mid-bands differences..)

Selecting type of transition (fade-in/fade-out) with one click, such as ... adding gap between songs (silence) or few second transition, half second transition...

Silent tracks may be added to playlists, which are silence, as set from 0 to 99 minutes.

Playlist may be set to pause after the currently playing file finishes (Automix mode) and then later press "Start" to begin from there. "Pause Playlist" track may also be added to a position in the playlist.

Microphone input may also be used non-realtime, by writing microphone input as audio files to hard disk, with option to record audio playback of the software with the microphone, with adjust of balance available.
Video files can be viewed when is audio of video file, by click of "..." button of playback unit, with select "Video", for using the softwares time-alter pitch-alter features with a video file.

Import of audio files reads tags (fields: artist,album...) from MP3,AAC,WMA files, the software does not support editing tags of audio files, although information can be edited within the program's song library.

Preferences/options of the software: are several options, though the options aren't very well layout, but are there nevertheless.

2-channel mixer unit of the software has high, mid low EQs, the filters used to construct the EQs may be tuned from the Edit menu, though user may also use the better parametric EQs by adding to the effect chains instead of the mixer's simple Hi,Mid,Low knobs.

Automix playlist playback may be set to "Song Sampler" mode, where the audio files are non-precisely, at set amount after seconds switched to the next audio file, as set, from 10 seconds to four minutes as the range,
which has an option where when reached the set amount of seconds, the file will start from there and is placed to the end of the playlist (Continues later).

Audio file library has option to right-click items, with click to search for artist, album clicked.

Audio file library search, is with options (optional): either words or both words, such are added before the search term in the field.

Audio files may be set to different colors, different from other audio files on the lists, for identification, or set to one of several "marked as" types, such as underlined, strikeout, hidden..

Audio files may be set to a value of created list of type groups such as "spoken word,instrumental..." which are set by right-click.
