16" the sub-octave -12 semitones 0.5 th harmonic
5 1/3" the fifth +7 semitones 1.5 th harmonic
8" the fundamental
4" the octave +12 semitones 2 nd harmonic
2 2/3" one octave and one fifth higher +19 semitones 3 rd harmonic
2" two octaves higher +24 semitones 4 th harmonic
1 3/5" two octaves and a third higher +28 semitones 5 th harmonic
1 1/3” two octaves and a fifth higher +31 semitones 6 th harmonic
1" three octaves higher +36 semitones 8 th harmonic
All of these except the 1 3/5" drawbar are either roots or fifths. The 1 3/5"
is a third. Each drawbar's colour indicates its relationship to the
fundamental pitch. The white and brown drawbars are called the
“consonants” and comprise all the roots and the lower fifths. The black
drawbars are called the “dissonants” and consist of the higher fifths and
the third. Using this set of harmonics, a wide range of sounds can be
created.
The Pedal only contains drawbars for the 16", 5 1/3", 8", 4", 2 2/3" and
2".
Each drawbar has eight continuously-variable degrees to which it can be
"drawn" or pulled out. A setting of eight is the loudest, while all the way in
silences the drawbar. Thus, each drawbar or "stop" can be "voiced" or
individually altered, even while the instrument is being played.
On its own, the fundamental drawbar generates a sine wave, thus
producing a pure flute-like tone. Adding odd harmonics creates a square
wave, producing a more clarinet-like tone. The odd harmonics "squared"
generate a triangle wave, thus producing a string-like tone. Finally, all
harmonics together generate a sawtooth wave, producing an oboe-like
tone.
Drawbar settings use the same kind of premise; various levels and
volumes of harmonics are used to create different sounds. There are a
limitless number of tone qualities and endless shades of dynamic level
available on the LinPlug Organ 3. Drawbar setting (00 6200 000) is an
example of a flute tone. Drawbar setting (00 4345 554) is an example of
