F1 Low: This establishes the gain in decibels of the lower frequencies of the audio range
F2 Mid: This establishes the gain in decibels of the middle frequencies of the audio range
F3 High: This establishes the gain in decibels of the higher frequencies of the audio range
F4 Bass Boost: This is used to increase or decrease the gain on the bass, in order to send to the amplification more
or less enhanced bass lines. The parameter is modified by pressing the relative function push button F4 repeatedly.
F5: Escape: This is used to return to the Effects menu.
F6 Out 1 Level: This establishes the level of the audio 1 output or Left/Mono.
F7 Out 2 Level: This establishes the level of the audio 2 output or Right.
F8 Out 3 Level: This establishes the level of the audio 3 output.
F9 Out 4 Level: This establishes the level of the audio 4 output .
F7 Chorus:
This is used to select the type of algorithm between Chorus 1, Chorus 2, Chorus 3, Chorus 4, Chorus 5, Flanger, Short Delay,
Feedback and four User Chorus using push buttons VALUE +/-. Once the algorithm has been selected, it is edited using F10 Edit.
F8 Delay:
This is used to select between eight types of pre-set Delays and four User Delays using the VALUE +/- push buttons. Once
the algorithm has been selected, it is edited using F10 Edit.
F9 Distorsion:
This is used to select between eight types of distorsion and four User Distorsion using the VALUE +/- push buttons . Once
the algorithm has been selected, it is edited using F10 Edit.
F10 Edit:
This is used to access the menu dedicated to programming the most important parameters of an algorithm.

EDITING AN EFFECT

The SD1 does not only choose the algorithm to be assigned to the DSPs but it also allows its substantial modification and saving in dedicated
memories. To modify an algorithm first it must be selected between Reverb 1, Chorus, Delay and Distorsion, simply by pressing the function
push button and choosing the algorithm. Without doing anything else at this stage press F10 Edit to access the menu.
Whatever the algorithm to be modified the Edit page shows some fixed parameters:
F4 Default:
This resets the parameters of the algorithm at their original values.
F5 Escape:
This returns to the Effects menu.
F8 Source:
This indicates the current algorithm selected to be modified, however by pressing function push button F8 several times, a
different algorithm can be selected.
F9 Destination:
This specifies the destination memory for the algorithm modified. It is selected by pressing the function push button F9
repeatedly.
F10 Save:
This confirms and saves the parameters modified in the memory selected using F9 Destination.
The single parameters to be modified are shown in the middle of the display that are selected using the CURSOR +/- push buttons and are mod-
ified using the VALUE +/- push buttons.

PARAMETERS FOR REVERB ALGORITHMS

Level:
This is the level of the signal.
Filter:
This applies an LPF filter that cuts out the higher frequencies.
Pre
Delay:
This is the length of the first delay.
Decay:
This is the decay tempo of the reverb.
Delay:
This is the length of the delay of the signal.
