It comes with the Serato DJ software, but it’s also compatible with Virtual DJ as well. Something I like about it is the abundance of controls nicely compact throughout the portable sized board. The 5-inch jog wheels have a great feel, look, and are very responsive. /epson-l355-software-download-mac.html. This is a tutorial of how to do a set up for virtual dj for scratching better and professionally in the art of mixing FB@Twi. The MIDI 16 has largesmooth touch-sensitive jog wheels, nice faders, and a good four-deck version of Virtual DJ LE all coming in at an excellent price-point for DJ's. The MIDI 16 is a four-channel USB professional DJ Mixer with DJ soundcard with additional MIDI buttons and the necessary features to let DJ’s get right into the Digital Mix.

Scratching is a DJ technique of moving the song back and forth to produce percussive or rhythmic sounds, while using the crossfader to cut sound with rhythmic patterns. This technique is usually performed on a turntable with vinyl, or on a DJ controller with touch-sensitive jog wheels.
While having DJ gear is a huge advantage when you want to scratch, giving you superior tactile control and feel, its possible to move song back and forth with just keyboard or mouse, and cut the sound in and out as well, and hence be able to create basic scratch sounds.
Keep in mind that VirtualDJ 2018 comes with built-in scratch feature called 'Scratch DNA' where you easily create nice automated scratch patterns and sounds that you can trigger from keyboard keys or controller pads / buttons : => Learn more about the ScratchDNA feature here

You can now move the song backward and forward using the above mapped keys. Alternatively, you can can also use the mouse on the scratch waveform or skin jog wheels, to move the song back and forth. Using the mouse might give you a more tactile feel and more 'live' scratch sound than using keyboard only.
To cut the scratch sound in rhythmic patterns, use the crossfader. This can also be mapped to keyboard. Or you can use the default mapping where 'Page Up' and 'Page Down' keys are mapped to control the crossfader.
(Tip: if you go to settings, under 'options', set crossfader to 'hamster' mode, and curve to 'scratch' for best results)
