Vcf - Frequency Control; Vcf - Key Follow - Roland SH101-M Owner's Manual

SH101-M
This parameter is active only in the
"Keyboard" working mode of the interface. The
parameter value can be controlled by MIDI CC
Nr. 41 – see chapter 5.1.2.2.
The parameter value can be set in range
of 0 to 127. If the value is equal to 64, MIDI
command Channel Aftertouch doesn't affect
instrument's VCO
parameter values from 65 to 127, VCO
frequency is increased directly proportionally to
the value of the Channel Aftertouch command
(frequency is increased by +4 semitones for
maximum Channel Aftertouch value = 127). For
parameter values from 63 to 0, VCO frequency
is decreased directly proportionally to value of Channel Aftertouch command (frequency is decreased
by -4 semitones for maximum Channel Aftertouch = 127) - see pic. 6.
4.2.3. VCF - FREQUENCY CONTROL (CC #42)
The parameter enables to decrease the
basic cutoff frequency of the VCF (set by the
VCF - FREQ slider on the instrument's panel).
Value of the parameter can be set in range of 0
to 127. If the parameter value is equal to 127,
the basic frequency of VCF set by the VCF
FREQ slider isn't affected. When the parameter
value is decreased, basic cut-off frequency of
the VCF is decreased accordingly, up to the
parameter value is equal to 0 when VCF is
closed fully (see pic. 7).
The parameter value can be controlled
by MIDI CC Nr. 42 – see chapter 5.1.2.2.
Remark: Since the interface cannot increase
the frequency of the VCF ("move the VCF - FREQ slider upwards") on the instrument's panel, it is
recommended to set the slider to maximum position (10) while the interface is active. This setting
enables full VCF cut-off modulation range by MIDI commands.
4.2.4. VCF - KEY FOLLOW (CC #43)
The parameter sets the level of VCF cut-
off frequency modulation by the position of the
played key on the master keyboard (i.e. tone
height).
This parameter is active only in the
"Keyboard" working mode of the interface. The
parameter value can be controlled by MIDI CC
Nr. 43 – see chapter 5.1.2.2.
The parameter value can be set in the
range of 0 to 127. If the value is equal to 64,
VCF isn't affected by key position. For the
parameter values from 65 to 127, VCF cut-off
