CHAPTER 16. INSTRUMENT, DRUM AND EFFECT RACKS 232
By default, your sliced MIDI data will form a chromatically-ascending staircase pattern in
order to trigger the correct chains in their original order. But you can create new patterns
by simply editing the MIDI notes. You can achieve a similar effect by dragging the Drum
Rack's pads onto each other to swap their note mappings.
Using Effects on Slices
Because each slice lives in its own chain in the Drum Rack, you can easily process individual
slices with their own audio effects. To process several slices with the same set of effects,
multi-select their chains in the Drum Rack's chain list and press
Ctrl
-G to group them to
their own nested Rack. Then insert the effects after this new sub-Rack.
For even more creative possibilities, try inserting MIDI effects before the Drum Rack. The
Arpeggiator and Random devices can yield particularly interesting results.
Slicing is most commonly applied to drum loops, but there's no reason to stop there.
Experiment with slicing audio from different sources, such as voices and ambient textures.
The same sorts of resequencing and reprocessing operations can be applied to anything
you slice  sometimes with unexpected results.
