Although Wersi instruments provide a good range of playing features and effects for
all their sounds, we can significantly increase this provision by using the many
adjustable parameters available in the Sound Factory. For example, we could add a
delayed vibrato, or a pitch bend, or a portamento, or a wah-
In this second piece we design a composite sound to re-
Most of the sounds that we hear on Wersi instruments have been created from a library of sound samples by a sound designer using audio processing software. Typically there will be two or three of these samples for each sound on the organ, and this software enables these to be combined together and manipulated to produce the sounds we see in the organ’s Sound Database. The Sound Controls menu in the OAS provides the player with a facility for adjusting a small number of parameters for each of these sounds, but the Sound Factory optional activation package enables a far greater range of adjustments to be made. There are three very useful applications for this package. Firstly, we can design a set of completely new sounds that have not been included in the Sound Database. Secondly, we can create a range of new and innovative playing features and effects that have not been made available in the OAS. Thirdly, if a particular sound is not entirely to our liking, we can make extensive tonal adjustments to it and also create new variants.
In this first piece we take a number of existing sounds from the Sound Database and
manipulate these in the Sound Factory to create a set of entirely new sounds that
are not present in the Sound Database. The sounds featured are a Vocal Whistle, a
Celtic Harp, a Balalaika (with built-
The wave, seagull and wind chime effects are taken from the organ’s Special Effects unit.

The extensive sound controls available in the Sound Factory make it possible to make comprehensive adjustments to the tonal characteristics of a sound. This enables us not only to customise an existing sound to our own particular requirements, but also to create different variants of that sound.
In this final piece by Joaquín Rodrigo we modify a number of existing sounds from the Sound Database to create a Peruvian Pan Flute, a Spanish Guitar and an Ethereal String Section.
