AK-4 Pro Breat Controller Curvature
The AK-4 Pro supports nine curvatures to give you the best dynamic and expressive sounds for
your keyboard synthesizer and plug-in VSTi or standalone VSTi performances. Create the best
sounds you’ve ever imagined with the Pro Breath Controller Curvature.
Every curvature has its own dynamic and feel. It depends on your selection of the Curvature;
some curvatures have a Slower ATTACK or DECAY, while the others have a faster ATTACK or
DECAY. You might need to reprogram your sounds to make them compatible with the breath
controller.
It is always best to adjust the ADSR (Attack, Decay, Sustain, Release) and VELOCITY intensity
or sensitivity to achieve the best result between your synthesizer and Breath Controller.
Why do you need to adjust the ADSR? Your actual Breath Controller is going to control both
the Volume and the ATTACK portion of your sound. We recommend adjusting the ATTACK to
0 and by turning OFF the Velocity intensity or sensitivity. (Refer to your keyboard/ synth
Owner's Manual in how to adjust the ADSR or VELOCITY control). For your own reference,
save the edited sound by adding BC at the end of the sound name i.e Accordion BC
The graph below represents the relationship between the input and output breath pressure.
