Hammond 340107 - Generator System and Voice Architecture

------
HOW THE ORGAN OPERATES
GENERATOR SYSTEM
Tone generation is accomplished by using the 6 channel 440/Multiplex generator
system for melody, accompaniment and pedal voices. The 434/435 LSI system gen-
erates the pedal tones in Ease of Play modes while an additional 435 LSI gene-
rates the arpeggiator tones. Therefore, the organ has the equivalent of eight
tone generating systems. The Multiplex generators are assigned to: (1) Upper
Manual Synthesis (2 drawbars); (2) Lower Manual Synthesis (9 drawbars); (3)
Lower String Ensemble and Tab Voices; (4) Brite or Synthes~s Percussion; (5)
Upper Manual String Ensemble, Synthesizer Voices, and Tab Voices; and (6) Pedal
Voices.
Instead of using "Second Voices
M
on this organ, five "full time" tab voices on
the upper manual and three on the lower are used. The upper manual voices are
TUBA 16', POST HORN 8', KINURA 8', DIAPASON 8', and VIOLIN 4'. The lower manual
voices are DIAPASON 8', HORN 8', and VIOLINA 4'. As implied in the "full time"
description they will add to all other voices.
In order to make the organ as easy to playas possible, it has been necessary to
establish some priorities for the Upper, Lower and pedals. They are as follows:
1. UPPER MANUAL
