frequency is increased directly proportionally to MIDI note number. For parameter values from 63 to 0,
VCF cut-off frequency is decreased directly proportionally to MIDI note number (see pic. 8).
Remark: It is recommended to set the VCF - KYBD slider on the instrument's panel to its minimum
position (0) while the interface is active so that "key follow" function is not doubled.
4.2.5. VCF - VELOCITY AMOUNT (CC #44)
The parameter sets the key velocity
modulation amount
frequency. Cut-off frequency of the VCF can
be increased directly proportional to the MIDI
velocity value. Value of the parameter can be
set in the range of 0 to 127. For the value
equal to 0, VCF isn't affected by the velocity
data, parameter value equal to 127 provides
maximal modulation level (see pic. 9).
This parameter is active only in the
"Keyboard" working mode of the interface. The
parameter value can be controlled by MIDI CC
Nr. 44 – see chapter 5.1.2.2.
4.2.6. VCF - AFTERTOUCH AMOUNT (CC
#45)
The parameter sets the modulation
amount of the VCF cut-off frequency by the
Channel Aftertouch MIDI command (key
pressure). Cut-off frequency of VCF can be
increased directly proportional to the value of
Channel Aftertouch. Value of the parameter
can be set in the range of 0 to 127. For the
value equal to 0, VCF isn't affected by
Channel Aftertouch, for parameter value equal
to 127 provides maximal modulation level (see
pic. 10).
This parameter is active only in the "Keyboard" working mode of the interface. The parameter
value can be controlled by MIDI CC Nr. 45 – see chapter 5.1.2.2.
4.2.7. VCA - KEY FOLLOW (CC #46)
The parameter sets the modulation
amount of the VCA by the position of the
played key on the master keyboard (i.e. tone
height). Value of the parameter can be from 0
to 127. If the value is equal to 64, VCA isn't
affected by key position. For the parameter
values from 65 to 127, VCA level is increased
directly proportionally to MIDI note number.
For parameter values from 63 to 0, VCA level
is decreased directly proportionally to MIDI
note number (see pic. 11).
This parameter is active only in the
