Once you have all your samples loaded and assigned, each sample can be passed through
a filter and amplifier which can in turn be modulated using envelopes, LFO, and MIDI controller
commands. Most samplers let you group samples together into zones or keygroups allowing you
to apply a single set of filters, envelopes, etc. This feature can save a lot of time in programming.
Imagine programming all of those settings on each of 100 samples without losing track of how
far you are in the process. Figure 6.40 shows all the common synthesizer objects being applied to
the “PianoC43.wav” sample.

Data Flow and Performance Issues in Audio/MIDI 6.2.4
Combined audio/MIDI recording can place high demands on a system, requiring a fast CPU and
hard drive, an appropriate choice of audio driver, and a careful setting of the audio buffer size.
These components affect your ability to record, process, and play sound, particularly in real time.
