Selecting and Playing Sounds
The Vintage Organ buttons lets you add vintage organ sounds to the upper
and lower 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.
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.
