SAMPLER BASICS
2.
Mapping
Mapping determines the range of notes on the keyboard or other controller that will play the sample,
and how the sample will respond to those notes - e.g. whether it will always play at the same pitch or at
different pitches corresponding to the notes played. You can, for example, have a single sample played
across the entire note range, several split or overlapping samples played in different note ranges, or
many samples each played by an individual key/note.
Step-by-Step procedure on page 46.
3.
Filter, EG, and LFO
If you want to actually modify the sound of your samples to create a desired musical effect, you might
want to apply:
• Static or dynamic velocity-controlled filtering to modify the timbre of the sound or created "wah-
wah" type effects.
Step-by-Step procedure on page 47.
• Envelope-generator-based amplitude, filter, or pitch variations such that the controlled parameter
varies over time whenever a note is played.
Step-by-Step procedure on page 50.

MAPPING
Filter cutoff (or center) frequency
controlled by note velocity,
envelope generator or LFO.
ENVELOPE
Envelope generators can produce time-based
variations in amplitude, filter frecuency or pitch.
