4. SWITCHING ON AND NORMAL FUNCTIONING
To switch on the instrument follow these simple rules:
1. Turn the [VOLUME] potentiometer to the left (closed).
2. When using headphones, do not wear them.
3. Switch on the instrument through the [POWER] switch on the rear panel.
4. Wait for the power-on sequence of the left side panel buttons’ leds.
5. Once the last led of the Black Octave keys ( Legend ), or of the [DRAWBARS SET B] ( Legend Live ) on both
manuals has switched on, the instrument is ready to be played.
6. Adjust the volume as needed and / or wear headphones if necessary.
After switching on, the instrument always recalls the following settings:
- VOLUME NORMAL/SOFT ( Legend Live only): NORMAL
- VIBRATO/CHORUS UPPER ( Legend Live only): off
- VIBRATO/CHORUS LOWER ( Legend Live only): off
- PERCUSSION ON/OFF ( Legend Live only): on
- PERCUSSION SOFT/NORMAL ( Legend Live only): SOFT
- PERCUSSION SLOW/FAST ( Legend Live only): FAST
- PERCUSSION 2nd/3rd ( Legend Live only): 3rd
- REVERB POST/PRE: POST
- REVERB HALL/SPRING: HALL
- DRIVE CLASSIC/ROCK: CLASSIC
- TONEWHEEL MODEL: ‘70
- ROTARY DIRECT: off
- ROTARY CLASSIC/ROCK: CLASSIC
- HOLD INT/EXT: INT
- PEDALS DIRECT: off
- PEDALS TO LOWER: off
- Drawbars Set of the upper and lower manual: B
- Transposition: 0
- Gospel function: off
4.1 WHAT ARE DRAWBARS AND HOW TO USE THEM
The electromechanic organ sound generation is based on 91 metal wheels with bumps (called tonewheels)
that revolve close to a magnet with a coil. The bumps of the wheels create a variation in the magnetic field,
thus generating a voltage and hence a signal which, controlled through the drawbars and amplified, becomes
sound.
Pipe organs generate sound by blowing compressed air inside a resonating tube, or pipe. Labial reeds
produce a pure sound (without harmonics), very similar to that of a flute, which is the type of sound generated
by an electromechanical organ with only one drawbar pulled out. The frequency of the sound generated by a
pipe is directly proportional to its length: the longer the pipe, the lower the frequency. The pipe producing the
root note is 8' long; shortening the length of one half, to 4', the note is an octave higher, while with a double
lenght of 16', the generated note is one octave lower.
Drawbars work the same way, and it is possible to note how the size, expressed in feet, decreases from left to
right, as in a graphic equalizer, where the frequency increases as one moves from left to right. The use of
drawbars can be compared to that of faders in a graphic equalizer: faders modify the timbre of the input
sound, just as drawbars in an electromechanical organ define the timbre by controlling the harmonics.
Drawbars on the left control the lowest harmonics, while those on the right control increasingly higher notes.
The only drawbar that does not follow this rule, as described below, is the second from the left
The level of the harmonic increases as the drawbar is pulled out, and the exact level is shown by the numbers
printed on the bars; the level is decreased by pushing the drawbar in.
