10. PLAYING THE PIPE ORGAN
Press the TYPE button n. 22 to shift to the next sound, the Pipe Organ. This is a one
manual organ with 9 stops, 3 couplers and the tremulant motor.
One important thing:
remember to increase the Reverb level a bit when playing this sound!
The drawbars, in this case, will function as on/off switches, just like the “stops” of a
real pipe organ that can be pushed in (off ) or pulled out (on). The middle position is
the threshold, and the on/off transition is smooth. Every stop corresponds to a series
of different pipes, some pipes are reused on certain note ranges. Pipes are organized
differently across the stereo field, most generally the lower pitches are most audible
on the left channel, and the high pitches are located more towards the right channel.
The Pipe Organ also supports presets A and B as well as the HOLD function, just like
VB3. Please refer to the previous chapter.
COUPLERS
The same buttons that were previously used for the
percussion sound with VB3 are now used for the so-
called “couplers”, which is a special mechanism of a
pipe organ that allows a single note to play on
multiple octaves.
Let's make an example: play the center C-note, now
push button n. 18, this will activate the “SUB OCTAVE”
coupler and you'll hear the lower C adding to the
sound; now push button n. 19 that will activate the
“OCTAVE” coupler, so that the higher C will also add
to the sound; lastly, button n. 20 enables the
“CANCEL UNISON” which will cancel the center note,
i.e. the note that you are actually playing, leaving only the lower C and the higher C.
If the “CANCEL UNISON” coupler is enabled and the other two are disabled,
you won't hear any sound. Actually, if you listen closely, you'll hear an airy
attack sound like air that blows through the key and doesn't reach the
pipes. Hey, it's physical modeling, after all!
TREMULANT MOTOR
This is an effect that can be activated using button n. 7. In pipe organs it's like a
rotating vent that produces a sort of tremolo effect by alternating the air flow
through the pipes.
