•

MID HIGH 

([6K])

: enhances / attenuates the signal in the frequency region with centre on 6

KHz.

If these equalization parameters (and therefore not TYPE) are set at –12 you will obtain attenuation

of the signal of -12 dB; conversely, setting them at +12 will give an enhancement of +12 dB. If the

parameters are set at 0, the signals will be unaffected by the influence of the equalizer.

If you now wish to set the equalizer as parametric, set parameter TYPE=PARAM.

In this case, the parameters are the following:

•

LOW 

([LOW])

: enhances / attenuates the signal in the frequency region with centre on 60 Hz.

•

HIGH 

([HIGH])

: enhances / attenuates the signal with frequencies over 6 KHz.

•

TYPE 

([MID MODE])

: sets the equalizer mode.

•

MID FREQ. 

(Mid Frequency, [MID])

: sets the region of frequencies, in the medium range, of the

signal to be enhanced / attenuated.

•

MID B/C 

(Mid Boost/Cut [FREQ])

: regulates the enhancement / attenuation of the area of frequencies

equal to that set with the MID FREQ parameter.

•

MID Q 

([Q])

: regulates the band width of operation in the medium range specified with the MID

FREQ parameter.

If the LOW, MID B/C and HIGH parameters are set at –12 you will obtain attenuation of the signal

of -12 dB; conversely, setting them at +12 will give an enhancement of +12 dB. If the parameters

are set at 0, the signals will be unaffected by the influence of the equalizer.

The LINKS function allows the RATE parameter of LFO1 and of CHORUS effect and the DELAY

TIME to be linked to the TEMPO parameter of the ARPEGGIO or the PHRASE RECORDER, and

to the MIDI Clock message present on the MIDI [IN] port.  All this is in order to guarantee perfect

synchronisation of the above sections or with a remote MIDI instrument.

See also point 10.3 for further information concerning MIDI synchronisation.

N.B.: If the MIDI signal referred to above is not present on the MIDI [IN] port in case of Link to the

MIDI Clock, the parameters linked to it will be set with the respective lowest value.

In order to provide information about the status of the parameters which may be linked, when the

video pages relating to the parameters referred to above are displayed from the Program

environment (therefore, in order to display the LFO1 Rate you will have to carry out a Swapping

operation), the display will show an “L” in square brackets against the parameters which have

been linked.
