Crossfader

The crossfader sits in the mixer between the two platters on the Mix tab. Fully left you hear deck A, fully right deck B, and in between both. For scratching, it’s your cutting hand: fast moves near the edges cut the scratch sample in and out.

Using the crossfader

• Drag the crossfader knob to move it.
• Double-click it to return it to the centre.
• Map a controller fader to it with MIDI Learn. By default, CC 1 (the mod wheel) controls the crossfader; see Default mappings.

The crossfader, its curve and Reverse are all host parameters, so you can automate them.

While you scratch with the mouse, you can cut with the keyboard instead. See Fader keys.

Curves

The box under the crossfader sets its curve: how each deck’s level changes as you move it.

Curve	What it does
Linear	Each deck’s level rises evenly with the fader. At the centre both play at half level.
Constant Power	A smooth curve that stays fuller through the middle, for blending two tracks.
Fast Cut (default)	A deck opens fully within a short distance from its closed side. Both decks are at full level through most of the travel, the classic scratch setup.

Reverse (hamster)

Turn on Reverse to swap the crossfader’s sides: fully left plays deck B and fully right plays deck A. Scratch DJs call this hamster style.

Utility pad crossfader cuts respect Reverse, so Cut to A always leaves deck A audible. The fader keys ignore it.

Feel options

The Feel window’s CROSSFADER group fine-tunes how the cut feels:

Option	Default	What it does
Cut-in lag	2%	A small dead zone at each closed side: the fader can travel this far before the sound cuts in.
Fast Cut width	5%	How far the Fast Cut curve travels, after the lag, to open fully.
7-bit hysteresis	On	A closed side needs one more MIDI step to open than it took to close, so a controller fader resting on the edge never flickers.

The Battle preset in the Feel window sets a tight crossfader for cutting.
