Select sounds, change parameters such as volume, reverb and many other parameters, and save everything in a Registration. You can save 300 Registrations, overlay and split up to 6 sounds on one MIDI channel. Hardware requirement: The app only works in conjunction with the optional hardware "V3-SOUND-CONTROL", a Bluetooth receiver in the form of a USB stick.

The MIDI keyboard is connected to the V3 Sound Expander using a standard MIDI cable.
