Impulse Expander - Yamaha VL1 Owner's Manual

Getting Started

Impulse Expander

The Impulse Expander works in conjunction with the Resonator, described below, to
simulate the effect of an instrument's resonant cavity or sound box. It can also be used to
simulate the acoustic environment in which the instrument is played.

In contrast to the Resonator, the Impulse Expander is more suited to the simulation
of metallic resonances and is thus invaluable for refining the sound of brass and metal-
bodied woodwinds. Other important effects are the ability to diffuse sharp attack sounds
and to give depth and realism to vibrato. In fact, the Impulse Expander should only be
used with voices which have a degree of vibrato or other cyclic variation, since its effect
is less noticeable on uniformly sustained sounds.
Since the Impulse Expander is not essential for all voices, it can be turned com-
pletely off when not needed. It also has "Wet Level", "Dry Level", and stereo
"Level Balance" parameters that allow its effect to be blended into the main sound
as required.
