How to play
Expression Patches
Wheel
The most important control in CBV is the wheel. By default, if you don’t touch
the wheel and you play notes you’ll hear nothing. That’s because you aren’t squeezing the
Squeezebox. Move the wheel up to increase the pressure on the bellows.
You can automate the
wheel
or use “Edit Keyboard Control Mapping...” to use another
control on your keyboard or MIDI-accordion.
Expression Scale / Const Expression
These
controls allow to set the dynamic range of the
accordion synthesizer.
Const Expression
adds a
constant value to the modulation input and
Expression Scale
decreases the impact of the
modulation.
Often MIDI-accordions pressure-sensors are unsteady and not accurate. If you’d like to make your performance more
steady and the MIDI-accordion easier to play: Increase the
Const Expression
and decrease the
Expression Scale.
Sustain Level
Add ADSR to the envelope. The default settings are similar to the response of the reeds of the model
accordion we used in development. Usually an accordion player will perform the ADSR-expression, if you’d like the
synthesizer to behave more like a piano, set a lower
Sustain Level
.
Cassotto
Adds a very slight lowpass filter that sounds similar to a real accordions cassotto
1
. It’s like a lowpass
filter frequency nob, that will never filter all sound, the maximum value turns the
Cassotto
off.
Piccolo / Clarinet / Tremolo / Bassoon
The reeds. These equal the 4” / 8” / 8” Tremolo / 16” stops of a accordion.
Please refer to the wikipedia page below.
Piccolo
is tuned one octave higher than
Clarinet
and
Bassoon
one octave lower.
If you select
Clarinet
and
Tremolo
you’ll get the typical accordion tremolo sound.
Clarinet
and
Tremolo
have a slightly
different pitch and therefore create a tremolo or beat.
Filter
is a LP 12-lowpass filter.
Tone
is a BP 12-bandbass filter, however it is
mapped to a reduced range.
Modulation pickup
Allows to change the
controller events that
will modulate the
accordion synthesizer.
