: Beat Locked Fade Region - Shows a crossfader "off" region created by holding shift while selecting
: Hamster Mode Toggle - Toggles between
gray regions being "off" and white regions being "off"
: Crossfader Transition Speed - How fast
the crossfader goes from "off" to "on" or vice versa
crossfader movement is much simpler than scratch editing. Any area can
be selected with a simple click+drag, and then turned on or off. To snap selections to the grid, hold down the Shift
key while selecting. The
keyboard keys to move the crossfader are:
A: Make selection gray ("off")
D: Make selection white ("on")
In default mode the gray regions (#2)
show where the
crossfader is off, and the white regions show where it is on. In
hamster mode (#3) these two colors switch functions, and the white
regions become the "off" regions.
The Fader Time (#4) controls how fast
moves between off and on. In real life this will vary depending on hand
speed and DJ mixer, so here it is completely adjustable from
instantaneous to as long as anyone could possibly need.
it too low will cause noticable clicking in the scratching sound,
because it will make transitions faster than physically
: Jump to Folder - Changes current folder
: Scratch Files (.sch) - Files of crossfader and record movement data
: Project Files (.spj) - Files that store midi note settings and the current wave file
The File Browser is used for loading scratch
and project files. It will display all the scratch, project, and wave
files in a given folder. The folder can be changed by the "Jump to
Folder" button (#1).
Scratch files can be sent to two different places.
Left clicking a scratch in the browser will send it to the Scratch
Editor. If no region is selected in the Fader Editor then the scratch
will over-write whatever is currently in the Scratch Editor. If a
region IS selected, however, the scratch will import as a scaled
version over-writing only the selected area. If this sounds confusing,
it is explained in further detail in the Scratch Saving and Pasting
Right clicking a scratch file sends the scratch to
the Midi Editor. Here it will be associated with a midi note. For more
information on the Midi Editor and project files, check the Midi Editor
The File Browser can also be used to
load wave files with a single click. If there is a directory of
wave files to preview, it is much faster to load them through the File
Browser than to load each using the "Load Wave" button.
Save Project Button - Brings up dialog box to save current midi
settings to a file in the current file
2: Midi Input - Used to select midi input device, such as Rewire or a USB midi controller
3: Scratch Note Name - The midi note that will trigger a given scratch to play
4: Scratch File Name - The scratch file that will be triggered by the corresponding midi note
The midi editor is designed to be fast. To associate
a scratch with a midi note, simply follow these two steps:
1) Play the desired midi note on the current midi controller
2) Right click a scratch in the File Browser
The scratch file name will then show up in the midi
editor to the right of that midi note. The scratches are always sorted
in order according to their midi note, with the current highest note
stationed at the top. Once a scratch is in the Midi Editor, playing the
corresponding note again on the current midi controller will trigger
that scratch to load and play.
As an additional note: scratches already associated
with midi notes can be moved around to different notes inside the
editor by clicking and dragging.
A record can
normally be played back at any speed. With a modern LP this makes for
33 and 1/3 rotations per minute. That means if a record is scratched at
exactly that speed, the sound created will be the same as if the record
was just being played. What if, however, a person wanted to scratch a
bassline from a record that has a bass sample on it? It then becomes a
matter of figuring out the different hand speeds needed to make
different "notes" above and below the original bass sample. This is
where the Musical Editing options of Scratcher come into play.
Any given "note"
is the same as a specific steepness within the scratch curve. By having
the computer do all the math, the slopes for every possible musical
interval in Western music are possible. To
chose an interval simply use the drop down "Musical Interval" menu.
Otherwise, the letters Q through I on the keyboard are used as
Each key corresponds to the number above it. That is, Q represents the
first note of a major scale, or normal playback speed. W is the second
of a major scale, E is the third, and so on. The following chart shows
key combinations and their purposes.
||Abbr. in Scratcher
||Major Scale Value
|Shift + W
|Shift + E
|Shift + R / Shift + T
|Shift + Y
|Shift + U
Entering any key
combination within this table will tell Scratcher to calculate the
necessary steepness to make that interval up from the original sample.
For those who know a little music theory, the Shift key is used to make
intervals minor or augmented/diminished.
Once an interval is selected, blue lines will show
up any time a point is selected. These lines are guides to show
the exact steepness needed for that specific interval, or note. To make
it easier to follow these guides, there are options to make breakpoints
lock to them automatically. The shift and control keys are used to turn
on locking. Simply press and hold either of them while dragging a point
to force it to the path.
Shift: Used to lock relative to the anchor point on the left
Keep in mind that since everything is relative to
normal playback speed, anything that changes the playback speed will
also effect these slopes. Changing the BPM of playback or selecting a
new part of a wave file to play will both have an effect on the musical
editing mode line guides.
Scratch Saving and
One of the most magical features of Scratcher, is the ability to paste
any scratch into another scratch and scale it in time. If that sounds a
little confusing, here is an example guide.
First, make a scratch
that you'd like to save or paste
To save, hit the "S
" key and a dialogue box comes up for the scratch
After clicking OK, notice a new addition to the Scratch Library
Your scratch has been successfully saved! Now to work with pasting
first open the scratch you want to work on by clicking it in the
Scratch Library, or create a new scratch by hitting "K
." Here I've used
a new blank scratch. Make sure you are in Fader Edit Mode (hit the "X
key to toggle edit modes). Now select the area where you want to insert
the scratch you already made, just as if you were going to change the
crossfader. In this case, I've chosen to map my scratch across the
After selecting an area, simply click on the name of the scratch you
want in the Scratch Library. It will now be put into the current
scratch scaled to fit exactly in the selected area!
There are really no limitations on where and how you paste it.
