Scratch Live 2.1 Manual
for Rane SL 3
Looping
You can save up to 9 loops per track; these loops are saved in the file, and will be present when you reload the track. To make a loop, set the in-point by clicking the in button, and the out-point by clicking the out button. To turn the loop on or off, click the loop button. If you want the playhead to jump to the start of the loop when you enable the loop, hold the control key and press the loop button.
To adjust the in-point of the loop, click the in button. You can use the arrow keys left arrow to move the in-point towards the start of the track, right arrow to move the in-point towards the end of the track. Hold down the shift key while pressing the arrow key to make coarse adjustments. Click the in button again to save the in-point. The same applies to adjusting the out-point.You can also use the control vinyl (or CD) to adjust the in- and out-point. Click the in button, then move the control vinyl. Moving the vinyl will adjust the in-point. Once you are happy with the new in-point, click the in button to save, and release the control vinyl.
The control vinyl will go back to controlling playback once the record is back up to normal speed. Using the control vinyl to adjust loop end points is optional — to turn this feature off, disable the adjust loops with vinyl option in the setup screen. There are 9 available loop slots per track. If a loop is set in a given slot, the background (behind the loop number) will be green. Press the x button to clear the loop. If you click on the locked loop symbol, a red border will appear. This indicates the loop is locked, and you will not be able to adjust the end points or delete the loop until you unlock it, by clicking on the number again.
NOTE: Looping applies to rel and int modes.
Auto-Looping
Auto looping allows you to create loops instantly. If the track has a BPM value simply click the number of bars you
wish to loop and Scratch Live will create the loop for you. The loop is snapped to the beats in the song detected by Scratch Live so even if you press the button slightly out of time Scratch Live will still create a perfect loop for you.
Five auto-loop buttons are available on screen at any one time. They range from 1/32 to 32 bars. The user can select the auto loop range with the < and > buttons.
Pressing an auto-loop button will create a loop start point from the nearest beat to the playhead (within reason), and set a loop endpoint in the future. Pressing auto-loop 1 while auto-loop 1 is active will deactivate the loop. Pressing a
different auto-loop button while looping is active will extend the endpoint of the current loop to the appropriate new auto-loop length.
You can also save an auto-loop to the next available slot. When using an auto-loop, a save button is visible where the lock loop button normally is.
NOTE: Auto-looping requires the track BPM to be set.
SEE SET AUTO-BPM FOR MORE INFORMATION.
The A - Slot
A special loop slot ‘A’ exists for auto-looping. The act of using the auto-loop buttons sets a loop in the ‘A’ slot, following the rules above. Turning a loop off using the auto-loop buttons returns you to the loop slot that you were previously in at the time you started auto- looping. Turning the loop off using the ‘loop’ button leaves you in the ‘A’ slot. The ‘A’ slot is not saved to disk automatically, pressing ‘save’ saves the loop to the first empty slot in 1-9.
Auto-looping shortcut keys are alt-1 to 5 for the left deck, and alt-6 to 0 for the right deck. They correspond to the looping buttons as laid out on screen. ie. if the onscreen buttons display 1 2 4 8 16 bar loops, alt-1 triggers 1 bar loop,
and alt-5 triggers a 16 bar loop.
Loop Roll
Loop roll performs a standard auto-loop, but when the loop is turned off, the playback position is returned to the position where it would be if it had not entered the loop (much like censor).
The other difference between loop roll and standard autoloop is the ‘roll’ button is momentary. The loop is engaged when the button is pressed down, and disengaged when the button is released. Use short loop lengths to
create “stutter” type effects.
To activate loop roll, hold control + alt while clicking on the desired autoloop increment, or use the keyboard shortcuts: control + alt + 1 through 5 for the left deck and control + alt + 6 through 0 for the right deck. (ie. the same as the autoloop controls with the additional ‘alt’ key as a modifier).
The range of values available for loop roll are 1/32 through to 32 bars. The shortcut keys will activate whichever loop lengths are visible on screen, i.e., if you have lengths of a 1/4 bar through to 4 bars visible for the left deck, control
+ alt + 1 will activate a 1/4 bar loop roll, control + alt + 2 will activate a 1/8 bar loop roll and so on.
Use the < and > buttons to toggle through the range of possible lengths visible on screen.
Loop Roll With MIDI
You can assign loop roll to MIDI in several ways:
After pressing the MIDI assign button in Scratch Live, press the control + alt keys, click on an auto-loop value, then click on the button/slider you want it mapped to on your MIDI controller.
Alternatively, you can assign the singular loop roll button to MIDI, then assign a MIDI knob or slider on your controller to the autoloop select knob (visible in the MIDI assign panel area when in MIDI assign mode) to change the values on the fly.
TIP: When you have the “Autoloop Select” knob assigned to MIDI, you have all of the loop roll lengths at your disposal. This allows you to roll up and down the loop length scale, to create interesting stutter and build-up effects.
NOTE: Like autoloop, loop roll requires a BPM value written to the ID3 tag in order to work. Build overviews with the “set auto-bpm” box checked and the proper range for your music selected to ensure an accurate BPM value.
