The Filter Menu
To complement the front panel controls in the Filter section, there are
other functions located within the Filter Menu.
This is selected by pressing the HOLD button in the
Amp Env section on the front panel. Use the BANK /
PAGE up/down buttons to scroll through the Menu
functions available - See the table below.
Velocity Sensitivity (Menu Page 1 ‘FILT Velocity’)
This setting is used to modulate the Cutoff FREQUENCY of the Filter
up or down in response to the velocity information present in incoming
note messages or notes played on the keyboard.
Set in the range -1 to -64, the Filter will close (the Cutoff FREQUENCY
will decrease) as velocity data is applied. With a range of 1 to 63, the
Filter will open (the Cutoff FREQUENCY will increase) as velocity data
is applied. Greater values will open (increase the Cutoff FREQUENCY)
as velocity data is received. At a setting of 0, note velocity will have no
effect.
Q Normalise (Menu Page 2 ‘FILT Q Normalise’)
This value controls the Resonance Normalise. At zero, when resonance
is applied, the main audio signal will remain at normal levels. Adjusting
clockwise will reduce the signal level in relation to the resonance level.
This feature enables the Filter to emulate many of the classic Filters
such as the Moog type, Oberheim type and Roland TB303* type.
The LFO Menu
To complement the front panel controls in the LFOs section, there are
other functions located within the LFO Menu.
This is selected by pressing the ON / OFF button in the
Amp Env section on the front panel. Use the BANK /
PAGE up/down buttons to scroll through the Menu func-
tions available - See the table below.
LFO Velocity (Menu Pages 1 & 8 ‘LFO1 Velocity’)
The intensity of the LFO may be set to respond to velocity. As an
example of this. Set the LFO1 depth control to a positive value from the
front panel such that pitch modulation occurs on Oscillator 1. Using this
Menu, setting the LFO1 velocity to a positive value. Notice that, when
pressing a key on the keyboard, a soft press results in a very small
amount of pitch modulation or wobble and a hard press results in a
large amount.
When an LFO is used in the mixer section as a modulation source, this
feature is useful for controlling the volume of each Oscillator in propor-
tion to how hard a key is struck.
LFO Delay Triggering (Menu Pages 2 & 9 ‘LFO1 MonoDelTrig’)
When the Polyphony Mode is set to any of the Mono options (see
Page 42), different LFO delay settings are available for legato playing
styles (notes overlapping).
When the first note of a musical phrase is played, it might be desirable
to have an initial delay on the LFO. (If the LFO is routed to pitch modu-
lation, a vibrato effect would be introduced after the delay time). For the
remaining legato notes, a non interrupted vibrato might be required.
Setting this to SGL (single) achieves this.
Setting this to MLT (Multi) sets the LFO delay to apply to every note
played.
LFO Keysync (Menu Pages 3 & 10 ‘LFO1 Keysync’)
Each LFO waveform may be restarted every time a key is pressed.
For example, if a siren type sound effect was required, an LFO using a
sawtooth wave would be set to positively modulate pitch. Each time a
new key is pressed, the pitch would climb from the same point
(because the LFO waveform would be restarted) rather than being at
an undetermined pitch position.
Note : If the LFO Common To All Voices function (detailed on Page
46) is set to ON for the LFO, altering this value will have no effect. How
a keysync is applied to the LFO is determined by the changing the
Synth Global Sync setting (found in the KS Synth Global Menu). See
Page 52 for details.
