This is a dedicated application for the multi-effects BOSS VF-1. By using this app, you can intuitively set the "2CH RSS" algorithm that can localize sound three-dimensionally. You can move the sound in real time. The two parameters that can be set are AZIMUTH and ELEVATION, which can be specified individually for the L ch and R ch. When the LINK switch is turned ON, the L ch and R ch can be moved together. First, specify the MIDI port. Specify the program (2CH RSS) with the PB15 button. If you change the window size, use the lower right button to modify the controller placement. Requires a MIDI interface. Some Bluetooth MIDI interfaces such as mi.1 and MD-BT01 can also be used.
