Loop function in iScratch allows users to create their own manual loops on the other side of the player by setting the “A”(Loop
In) and“B”(Loop Out) points freely, with the option to EXIT and Play Loop.
Loop In and Loop Out allows user to set up a seamless loop.
Play Loop allows DJ to restart the loop in the Loop In Point.
Exit Loop will clear the loop at any point.
Scratch
Scratch is the main feature of iScratch. Scratch automatically record the music up to 24 seconds while the music is playing.
Therefore, users can rewind and fast forward the music within the 24 seconds.
Cross fader
The cross fader does two things at the same time: It fades between the two music sources, allowing you to blend from one
program into a new one, but also it does the exact opposite to the CUE channel. This allows you to cue up a new song on the
player that ISN‟T being sent to the main output. This allows you to cue up to a precise spot so that you can start the new
program and quickly cross-fade to it to align the beat of the two programs.
