Pitch-lock
Adjust the playback speed of deck without altering the musical pitch. When beatmixing, pitch-lock allows to sync the decks to the same tempo.

BPM Detection
BPM or Beats Per Minute is a unit used to measure the tempo of music. Disco XT automatically detects and shows the tempo of song that is playing. You can also process BPM for playlists or for your entire library.

Automix
With a touch of a button, you may put Disco XT to automix playback. In Automix Disco XT plays and fades songs together without any user intevention. Take a break from mixing when needed. Comes with several fading options, crossfades, gap between songs, fade outs and allows the user to create fading as well. Semi mix mode allows automatic playlist control while doing transitions manually.

Fade Editor
Create your own automated fades with the built-in fade editor. Includes several built-in fades for many different styles of mixing and music.

Automatic Gain Control
Disco XT adjusts song levels automatically for professional balanced playback. Optimal end points for songs are detected for gapless playback.

Talkover
Use your microphone with Disco XT to talk over your mix. Give announcements and talk about upcoming songs.

Playlist Cueing
Cue up start and end times for songs on the playlist without loading the songs to decks. No more need for waiting until the song is close to being played to be able to cue the song.

Save Mixes
Record your mix output with all the transitions and effects. The recorded mix can be automatically split to separate tracks while still keeping the transition between songs. The record mixes are normalized to give maximum loudness possible.

Customize
The interface is split into several devices: waveform view, looping, effects and more. You can show/hide devices as you wish and only keep the ones you use to save screen space. Includes tabbed browsing for music library and playlists. Includes different skin options and user choice for coloring from red to blue and anything between.

Waveforms
See what you are going to hear. You can detect incoming changes in song and inspect song ends with the waveform displays. Waveforms can be zoomed, which allows to see closer to the song for setting start points or loops, and then zoom out to see further in to the future.

Hit Sampler
Play short audio samples over the mix. Samples can be recorded with microphone or taken from an existing audio file. Includes pitch and tempo controls and effects.

Effects
Disco XT comes with high quality effects including reverbation for giving more room to the sound, tempo-synced delays, sweeping phasers and resonant filters. Includes limiter/compressor for distortion-free playback.

User EQs
Disco XT includes High, Mid and Low EQs that can be adjusted and constructed entirely by the user . For suiting specific environments, speaker systems and musical genres use the 18-band equalizer with spectrum view.
