5.3 DRIVE
Legend Solo
The Drive effect of faithfully reproduces the sound features of the analog distortion; the higher
the input signal to the amplifier, the greater the distortion. You will notice therefore that the effect depends on a
number of factors including the position of the expression pedal, the level and number of pulled-out drawbars
and the amount of notes played (at low volumes, for example, it is necessary to play many notes to drive the
signal to saturation.
Use the [DRIVE] potentiometer to adjust the quantity of distortion.
Through the [DRIVE CLASSIC/ROCK] button, you can also select the type of distortion effect.
The led off corresponds to the CLASSIC effect, i.e. the distortion obtained through the internal
valve amplifier of the classic rotating speaker used with electromechanical organs. The ROCK
effect (led on) generates a sharper distortion, typical of guitar valve amplifiers from the '70s.
This effect simulates the signal distortion generated when a valve amplifier connected to the organ
is driven into saturation.
5.4 ROTARY
Legend Solo
The internal Rotary effect simulates the classic acoustic effect produced by a rotating speaker
connected to the organ. This amplification and diffusion system became widespread with the advent of
electromechanical organs. It consists of two sections, one dedicated to high-pitched tones and the other to
bass. Both could rotate at different speeds, producing a peculiar three-dimensional effect due to the rotation of
the speakers. This effect is the result of the sum of the Doppler effect, due to the relative movement of the
sound source from the listener, and the sound reflections resulting from the rotation.
The Legend Solo effect allows to simulate as closely as possible both the continuous pitch variations caused
by the different rotations of the speakers and the particular resonances generated inside the cabinet.
Through the [SLOW] button you can select the low speed, while using the [FAST] button is
selected the high speed. Pressing the selected speed button (indicated by the LED on)
will stop the speaker rotation (Brake mode).
The speed of the Rotary effect can also be controlled through a switch pedal connected to
the [ROTARY] jack on the rear panel. For more information on the pedal, read par.3.2.
With the [ROTARY CLASSIC/ROCK] button it is instead possible to select the listening mode of the
rotating speaker. The CLASSIC type simulates the speaker as it is actually perceived by the
musician. In this mode, the led turns off. The ROCK mode simulates the sound of a rotating
speaker as recorded by a microphone. In this mode, the led turns on.
Pressing simultaneously both buttons [TRANSPOSE SELECT] and [ROTARY CLASSIC/ROCK], it is possible to
eliminate the Rotary effect from the outputs [LEFT], [RIGHT] and [PHONES]. When the Rotary effect is
disabled, the [ROTARY CLASSIC/ROCK] button LED lights up in red.
