The AkousKontr is German 4/4 four strings Upright bass recorded from both the pickup and with a pair of Electrostatic Microphones.
On the top of the interface, you can control the behavior of the instrument:
Legato mode: you can choose wether playing a legato will trigger Hammer ons, slides, sustains, or simply have no effect.
The legato distance will define the maximum interval that in which the legato will apply.
The Sensitivity will set the minimum volume for velocity 1 and give you access to all the dynamics that you want.
The release Volume: the sound produced when you release a string if a note was going on.
AkousKontr was recorded both from the Microphone and using the pickup and you can change the volume of each one from the interface.
