User Manual

– DECAY MODE –
From KEY MODE, press and release the MODE/PRESET encoder once to put the
Ravish into DECAY MODE, denoted by the DCY LED being lit as well as a “D”
displaying briefly on the left segment display. In this mode the user can change the
note decay of the lead sitar sound. This parameter ranges from 0 to 9 with 0 being
the shortest decay and 9 being the longest. The default value is 3.
– MODULATION MODE –
From DECAY MODE, press and release the MODE/PRESET encoder once to put the
Ravish into MOD MODE, denoted by the MOD LED being lit as well as an “M”
displaying briefly on the left segment display. In this mode the user can add
modulation to the sympathetic strings. The modulation is intended to emulate the
sound of a tanpura (aka tambura), an instrument commonly used to accompany the
sitar in live performance. As this parameter’s value increases, the modulation’s rate
gets faster. The default setting is 0 (no modulation).
– Q MODE –
From MOD MODE, pressing the MODE/PRESET encoder once will put the Ravish in Q
MODE, denoted by the DCY and MOD LEDs being lit as well as a “Q” displaying
briefly on the left segment display. In this mode the user can adjust the Q setting of
both the lead and sympathetic strings. This parameter ranges from 0 to 4 with 4
being the most “sharp” or “synthetic” setting. The default setting is 4.
– PITCH MODE –
ONLY AVAILABLE WHEN AN EXPRESSION PEDAL IS PLUGGED INTO THE PITCH EXP
JACK. With an expression pedal plugged into the PITCH EXP jack, from Q MODE,
pressing the MODE/PRESET encoder once will put the Ravish into PITCH MODE,
denoted by the KEY, DCY and MOD LEDs being lit as well as a “P” displaying briefly
on the left segment display. Here the user can change the maximum number of
semitones the lead sitar sound will bend at the expression pedal’s toe down position.
The default setting is 2 (one whole step) but this parameter ranges from 1 semitone
to a full octave (signified by the letter O). The expression pedal only bends up in
pitch.
– FREEZE MODE –
When in any mode other than KEY MODE, pressing and holding the PRESET
footswitch freezes the sympathetic strings indefinitely. While frozen, all controls are
still functional and can be tweaked to the user’s taste.

– I/O CONNECTIONS –
INPUT – Connect the output of your instrument or another effects pedal to this
jack.
MAIN OUT – This jack contains the dry, lead sitar and sympathetic string signals.
When a cable is plugged into the SYMPATHETIC OUT, the MAIN OUT contains only
the dry and lead sitar signals.
SYMPATHETIC OUT – This output contains only the sympathetic strings signal and
is intended for use with external effects and/or to go to a separate amplifier. When
this output is in use, no sympathetic strings will be present on the MAIN OUT.
DRONE EXP – An optional expression pedal* can be plugged into this jack for
manual control of the Ravish’s sympathetic strings. With the expression pedal in the
heel position, no sympathetic strings are present in the mix. As the pedal is rocked
forward, the sympathetic strings will fade in and freeze. At the toe-down position,
the volume of the sympathetic strings will be at the SYMPATHETIC LEVEL knob
setting.
PITCH EXP – An optional expression pedal* can be plugged into this jack and used
to bend the pitch of the lead sitar up. Once the expression pedal is plugged in, a
menu becomes available by pressing and releasing the white MODE/PRESET knob
past the Q setting. All three of the MODE LEDs will light up and the right segment
display will show how many semitones the pitch can be bent up.
*The expression pedal must have a Tip-Ring-Sleeve connection. It is important that the
expression pedal have the correct polarity. The tip of the plug must be connected to the wiper
of the potentiometer inside the expression pedal. If you are not sure what type of expression
pedal to use, try one with a polarity switch so that it will work with many different types of
instruments. Some suggested Expression Pedals: M-Audio EX-P, Moog EP-2, Roland EV-5 or
Boss FV-500L. You may also connect a control voltage to the jack with a TS plug. The Control
Voltage range must be between 0 V to 5 V.
– POWER –
Use the supplied AC adaptor to power the Ravish. Plug the barrel connector of the
adaptor into the 9V power jack located at the top of the unit. The Ravish requires 9
– 9.6VDC at 200mA with a center negative plug. The Ravish accepts Boss™ style AC
adaptors. The actual current draw of the Ravish is 160mA.
