Velocity Sensitivity
Summary: Determines how the filter 1 and filter 2
cutoff frequencies change in response to veloc-
ity changes (e.g. keyboard dynamics).
Settings: -7 ... +7
Procedure: Use the
select the Velocity Sensitivity ("Vel.Sens" on
upper LCD line) parameter. Use the [DATA EN-
TRY] control, [-1/NO] and [+1/YES] keys, or
numeric and [ENTER] keys to select the required
degree of velocity sensitivity.
Modulation Sensitivity
Summary: Determines the sensitivity of the filter 1
and filter 2 cutoff frequency to modulation ap-
plied via the LFO and appropriate controllers.
Settings: -7 ... +7
Procedure: Use the
select the Modulation Sensitivity parameter
("Mod.Sens"). Use the [DATA ENTRY] control,
[-1/NO] and [+1/YES] keys, or numeric and [EN-
TER] keys to set the required degree of modula-
tion sensitivity.
Details:
Plus "+" settings produce higher cutoff frequen-
cies in response to modulation — i.e. the greater

and cursor keys to
Details: Plus "+" settings produce higher cutoff fre-
quencies in response to higher velocity values
— i.e. the harder a key is played, the higher the
cutoff frequency. The maximum setting of "+7"
produces the maximum level variation in re-
sponse to velocity changes. Minus "-" settings
produce the opposite effect: lower cutoff in re-
sponse to higher velocity. A setting of "+0" re-
sults in no cutoff variation.

the modulation, the higher the cutoff frequency.
The maximum setting of "+7" produces the
maximum cutoff variation in response to modu-
lation. Minus "-" settings produce the opposite
effect: lower cutoff in response to modulation.
A setting of "+0" results in no cutoff modula-
tion.
When setting up the low-frequency oscilla-
tor or a controller to apply cutoff modulation,
this parameter must be set to a value other than
"0" for pitch modulation to take place.
