The Loop Machine allows recording, playing back, and overdubbing multiple layers of sound. The loops can be synchronized with the host, or to the metronome tempo in stand-alone mode. Furthermore, individual layers, or the mix of all layers, can be exported as WAV files.
As a practical example, you could record four measures of rhythm guitar, then overdub a lead, then a harmony, some rhythmic slides, etc.
Parameters
When nothing has been recorded into the Loop Machine, the pLay button
(arrow symbol) has a red outline. Pressing the pLay button has different
functions depending on the Loop Machine status.
Press once to start the recording. The Button glows red.
Press again to stop recording and begin loop playback. The Button glows green.
Press again to enter overdub mode (the Button glows yellow). Existing material plays back, but you can record over this. When the loop re- peats, you can continue overdubbing.
From this point on, pressing the pLay button toggles between Play and
Overdub modes. Each time you do this creates another layer (the Layers indicator shows how many layers have been recorded). It’s convenient to be able to go into Play mode to practice your part for the next loop, then return to Overdub mode.
Press the Stop but ton (X symbol) once to stop the loop from
playing. The Button will have a red outline for a few seconds; if you click again while the red is showing, all layers will be erased. The beat button enables a flashing indicator on the beat.
The progreSS Meter shows the current time within the loop. Loop tiMe
shows the total loop time, while reC tiMe shows the current time within
the loop. ► ► ►

While the Loop Machineis stopped, you can dou- ble-click on the Stop button to erase the various layers.
GUITAR RIG 3 – 170
reC voL adjusts the level feeding the Loop Machine.
pLay voL adjusts the Loop Machine playback level.
undo deletes the current layer. You can press undo repeatedly to delete
layers, starting from the most recent.
redo restores the most recently-deleted layer.
The Load button (folder icon) calls up Loop Machine files, which have a
.ls suffix. These consist of the audio files and all settings for a particular loop.
The Save button (floppy disk icon) saves Loop Machine files, which have
a .ls suffix and consist of the audio files and all settings for a particular loop.
exp Mix exports the entire collection of loops as a single mixed WAV file.
exp Lay exports the current loop as a WAV file.
Click on the (+) SyMboL to reveal expert mode, with the following
parameters.
autoStart causes recording to begin when the Loop Machine detects that
you have started playing.
overdub MuLtipLy allows recording a longer loop over a shorter loop.
reverSe plays back the layers in reverse mode, like 60s-type “backwards
tape” effects.
reC pan places the recorded signal in the stereo field. Thus, one overdub
could go in the right channel, and another overdub in the left channel. SynC synchronizes the LFO speed to the metronome tempo, which is derived
from the SynC setting in the Toolbar.
SynCHingtoHoSt: The Loop Machine transport starts, stops, and rewinds,
in synchronization with the host.
%
Although you can Undomultiple layers, you can Redo only to the most recently un- done layer.
SynCHingtoMetronoMe: This quantizes the loop length to the beat, even if
you stop recording slightly before or after the beat. Loop a/b toggles between two loops recorded previously.
4.14.2 Split
This device splits the signal path in two directions, thus allowing parallel effects. For more information on series and parallel effects (as well as optimal placement of effects), see Appendix C, “Tips on Creating Your Own Rig”.
Creating a Split
To create one split (Split A), drag the desired Component(s) in between the Split A and Split b sections.
To create the second split (Split B), drag the desired Component(s) in between the Split B and Split Mix sections.
GUITAR RIG 3 – 172
Here’s what a particular split looks like in GUITAR RIG 3. Split A feeds the Skreamer, Equalizer Shelving, and Ensemble Components. Split B feeds the Distortion and Wahwah Components.
Parameters
CroSSfade determines the mix between the A and B split. When fully left,
you’ll hear only the A split. When fully right, you’ll hear only the B split. pan is separate for each split, and determines where the split will appear
in the stereo field. Example: If A is panned left, B is panned right, and CroSSfade is set to the center, you’ll hear only the A split from the left
channel and only the B split from the right channel. If you now pan A to the right, you’ll hear both splits out of the right channel, and nothing from the left channel.
Stereo input L/r SpLit allows processing each stereo channel separately.
This is particularly useful if you play with two guitars through GUITAR RIG 3 and want two different sounds. Using this option with a Chapman Stick can be interesting as well, as it enables you to process the high and low strings with different effects.
The +/- SwitCH varies the polarity (also called “phase”) of the B split.
Split Tips
The Split module is extremely powerful:
Because you can drag multiple Components into a split, it’s possible to have parallel strings of series effects.
You can use more than one Split Component in a rig, and place Components inbetween them. Therefore, you can split a signal into two paths and use the CroSSfader to adjust the balance of the two splits.
This total sound can then be processed by additional effects, before going to another split.
