Audio tracks are the parallel "tracks" you see in sequencer software. Each audio track defines the attributes of the audio track, such as the track's timbre, timbre library, channel number, input/output port, volume, etc.

When you use a sequencer, the most we deal with is the audio track. A audio track corresponds to a part of the music, which records MIDI or audio data at a specific time position. Each track can be defined as the performance of an instrument. All sequencers can allow multi-track operation, which means that all tracks of a song, whether MIDI or audio, can be played at the same time. This means that musicians can complete a piece of music step by step. For example, we can play the drums first to give the whole music a rhythmic backbone, then play the bass to match the rhythm of the drums, then play the guitar to the beat, and finally Co-write and sing the music. A sequencer can do anything. All musical elements in the sequencer are displayed as MIDI or audio event bars. We can easily edit these event bars with the mouse, such as moving, copying, pasting, and cutting. These processes are collectively called arrange. Also, if there are some errors and defects in your music, the sequencer can also use the corresponding editor to edit the event bar in detail.

There are some powerful sequencers that can downmix individual audio tracks: increase or decrease the volume of the track, change the left and right phase, and add reverb or delay effects. Like CubasisGO! Cubase VST can even be played in real time using the built-in virtual synthesizer. When you've finished creating the entire song, you can save it to your hard drive and create a CD or convert it to an MP3 file.
