EXi: CX-3 Tonewheel Organ
5–2: Drawbars
5–2a
The drawbars are the heart of the CX-3. These settings
control the basic harmonic content of the sound, the
perceived fundamental pitch, and the basic volume
level.
Use Tone Adjust for physical drawbars
Using Tone Adjust, you can map the drawbars to the
nine front-panel sliders, including both sliders 1-8 and
the Master slider.
Like traditional tone wheel organs, the throw of the
sliders is reversed from that of a mixer: all the way up
is 0, and all the way down is the maximum (8).
Wrap-around
As with traditional organs, the tone wheels produce
pitches between C2 and F#8. Depending on the notes
that you play, certain drawbar settings may imply
pitches outside of this range. In this case, the drawbar
pitches will be "wrapped around" by one or more
octaves to fit within the available range.
For instance, the 1' drawbar would normally sound 3
octaves above the note that you play. If you play a D6
on the keyboard, this would imply that the 1' play a
D9. Since the tone wheels can't play a D9, however, the
1' drawbar is "wrapped around" to the highest
possible D - a D8.
The same thing will happen on the low end. For
instance, the 16' drawbar normally sounds one octave
below the played note. If you play an F1 on the
keyboard, this would imply that the 16' sound at F0.
Since this is far below the range of the tone wheels, the
16' sounds at its lowest possible F - an F2.

5–2a: Lower Drawbar Levels
These parameters control the individual drawbar
volume levels for the Lower split. The drawbars
express their pitches in terms of feet, referring back to
pipe organs, in which halving the length of a pipe will
raise its pitch by one octave. So, 8' is an octave higher
than 16', 4' is an octave higher than 8', and so on.
You can adjust these parameters by using the on-screen
drawbar graphics, or use the physical faders via Tone
Adjust, as described above.
Note that when Split is turned Off, only the Upper
drawbars are used; the Lower drawbar settings will
have no effect.
16'
This is the volume for the lowest drawbar.
0 means that the drawbar will be silent, and 8 is the
maximum volume.
5-1/3', 8', 4', 2-2/3', 2', 1-3/5', 1-1/3', 1'
These set the volume levels for the remaining 8
drawbars.
5–2b: Upper Drawbar Levels
These parameters specify the level for each drawbar
used by the Upper split. Also, when Split is turned
Off, the Upper drawbars are used for the entire
keyboard.
The settings are just the same as for the Lower
drawbars. For more details, please see "5–2a: Lower
Drawbar Levels," above.
