Lfo And Velocity - KETRON SD1 User Manual

same time with After touch and Modulation Wheel. Choose whether to modulate (control) a parameter with After touch or Modulation Wheel.
This aspect is a matter of preference and skill in controlling the keyboard and wheel. For example it may be more handy to modulate the cut-
off point of the filter with after touch rather than with modulation wheel. Some simple experimenting will allow you to make your timbres much
more lively and dynamic. To select any one of the parameters and the column use the CURSOR +/- push buttons and enter the modifications
using the VALUE +/- push buttons. Below is the explanation of the individual parameters:
CUT OFF: This enables the control of the opening and closing of the filter, altering the cut-off point of the filter. It is used for example
to create the analogue type sweeps or to confer additional harmony to a sound.
LFO Pitch: This enables the modulation on the pitch (Vibrato), controlling the modulation intensity of the LFO.
LFO Amplitude: This enables the modulation on the Amplitude (Tremolo), controlling the modulation intensity of the LFO.
LFO Filter: This enables the modulation on the Filter, controlling the modulation intensity of the LFO.
Volume: This controls the Volume via the After touch.
Wha Wha: This controls the Wha Wha effect via the use of the Modulation Wheel.
Slide (Vel): This affects the tuning of the sound, creating a sort of slight pitch bend each time a key is pressed strongly. It may prove
quite useful when playing to realistically simulate the sound attack typical of wind instruments, such as the Sax and Trumpets.
Attack: This makes all the parameters controlled with After touch start working with a slight and gradual delay. If used skilfully it con-
fers amazing expressiveness to the leads. To hear its affect, at least one of the parameters amongst those listed must be con-
trolled by After touch and obviously the After touch must be used. It is quite handy, for example, when assigning a pitch bend
to the After touch and playing with high velocities that could trigger the After touch. This system safeguards the use of the
After touch with additional control.

LFO AND VELOCITY

Press F10 LFO Velocity to access the parameters dedicated to the use of the LFO and the velocity to control some crucial timbre parameters.
To select a parameter use the CURSOR +/- push buttons and the VALUE +/- push buttons to modify the value. Below is the description of the
individual parameters:
LFO 1 (DCO) Rate: This establishes the velocity of the LFO dedicated to the pitch. Higher the value, faster will be the vibrato.
LFO 1 (DCO) Depth: This specifies the operating intensity of the LFO on DCO, therefore generating a Vibrato effect.
LFO 1 (DCO) Delay: This specifies the delay with which the LFO will affect the DCO for the vibrato effect.
LFO 2 Rate: This establishes the velocity of the LFO dedicated to the control of the filter and the amplitude.
LFO 2 (DCF) Depth: This specifies the operating intensity of LFO on the cut-off point of the filter, therefore generating a closing and opening
effect of the filter that, if the Resonance is set at high levels, can produce a primitive wha wha effect.
LFO 2 (DCA) Depth: this specifies the operating intensity of the LFO on the amplitude, with the result of obtaining a tremolo effect.
Velocity Slope: This is used to modify the response curve to the Velocity for the User Voice being modified that, at zero, mutes the timbre.
Velocity Filter: This controls the opening of the filter according to the key dynamics. Value 64 is the standard condition. Lower values
obtain a less brilliant sound, even when playing at high velocity.
Octave Shift: This shifts the octave of the User Voice by a range within - 2 octaves and +2 octaves.
