Channeling

OUTPUT MATRIX

For a better understanding of the entire channelling system for individual stops, we start with the description of

Output Matrix, instead of Chest Layout. Output Matrix is a channelling system organized by matrix; the structure

has 4 inputs and 2 outputs. Each Output Matrix input (Matrix IN 1

, Matrix IN 2, Matrix IN 3, Matrix IN 4)

can be assigned to one or both outputs (INTERNAL/EXTERNAL) with different percentage of sound.

CHEST LAYOUT

In this section it is possible to assign for each stop the type of wind-chest conﬁguration (Chest Type) and the

Output Matrix inputs where to send it to (To MatrixIN). The Chest Type voice contains the following wind-chest

conﬁgurations (acoustic simulation of the organ pipe's position on the corresponding wind-chest ):

CENTRAL PEAK CONFIGURATION

Monophonic basses at the centre and progressive separation of the sound towards the treble (this conﬁgu-

ration allows to optimise the efﬁciency of acoustic sound boxes in the basses).

LATERAL WINGS CONFIGURATION

Monophonic treble at the centre and progressive separation of the sound towards the basses.
