Selecting and Playing Sounds
The Vintage Organ button lets you add three types of vintage organ sounds
to the upper, lower, and pedal parts.
In addition, you can also use the harmonic bars to modify the selected sound
as desired.
The ATELIER provides nine harmonic bars for the upper part and lower part
respectively, and two harmonic bars for the pedal part.
Each harmonic bar is assigned a sound of a different footage (pitch), and by
layering these sounds you can create a variety of organ tones.
Harmonic Bar
By sliding the harmonic bars forward or backward (in or out), you can adjust
the volume of the various footages.
The volume can be adjusted over nine steps (0–8).
When a harmonic bar is pulled out all the way (8), the volume is loudest.
When it is pushed in all the way (0), there will be no sound.
8’ is the footage that forms the basic pitch of the sound; this is the center
around which you create the tone.
Each harmonic bar is assigned a sine wave (a pure pitch without overtones)
of a different pitch, and by combining these pitches you can create a wide
range of sounds.
Creating Organ Sounds (Vintage Organ)
You can use the Solo part’s
harmonic bars to adjust the
volume of the Solo part voice.
If you’ve selected
“
Pipe
”
or
“
Theater
”
as the vintage organ
type, the harmonic bars will
turn the various footages on or
off.
