vKA delivers most of the features of the VCS in an intuitive, easy to use manner. Since the APC40 was designed as a control surface for Ableton Live, vKA allows use of the APC40 with Ableton Live even while controlling a Kyma sound. vKA has special “smarts” to alternate between “Live mode” and “VCS mode” without missing a beat. vKA with the APC40 may well be the best option if you like to use Kyma on stage.
This diagram shows how vKA uses certain APC40 controls (in yellow) to achieve Kyma VCS functionality.
vKA supports "Midi over OSC" technology, allowing vKA to communicate with Kyma on Paca(rana) setups without the use of physical interfaces.
