Tremolo (optional)
The Gospel Organ stop has it’s own independent tremolo. This special stop belongs to the swell
division (Opus 5/10/20 AGO) or to the choir division (Opus 30 AGO).
When you use couplers (and/or the CF piston on the Sweelinck 5/10/20 AGO) the Gospel Organ
Tremolo will be coupled to the corresponding keyboards.
Chorus
To avoid the organ sounding too sterile, the instrument is designed with various stops tuned
differently in relation to each other. These small differences give the organ a broader, more
lively character. Switching on this stop will intensify the difference in tuning between the various
voices.
Intonation 2
Intonation determines the sound of the organ. In pipe organ-building the voicing is a very
important part of the building process. Every stop will be adjusted note by note to the room
where the organ is installed.
Your organ has two intonations, a romantic and a baroque intonation. In general a romantic
organ is wider and sounds symphonic, while a baroque organ is brighter and more tightly tuned.
Also see under “Choice of temperament”.
MIDI-tabs
The programmable MIDI-tabs are a special group of accessories. See under “MIDI applications”
and "Programmable MIDI".
Display
A so-called 7-segment display is located on the right side next to the keyboards. This display
has several functions:
When the PGM thumb piston is not switched on the display will show the chosen memory group
of the capture system. Also see under “Using free combinations (capture system)”.
When the PGM thumb piston is switched on, the display will show the required data for
programming the MIDI-tabs. See under "Programmable MIDI".
