JX-8v is a dedicated MIDI controller plug-in designed for seamless integration with Roland's JX-8p and MKS-70 hardware synthesizers. It facilitates precise control over MIDI communication, enhancing the user experience by allowing detailed management of data flow between your DAW and the hardware synths. The plug-in supports flexible MIDI routing, enabling users to configure input and output ports to suit their workflow.

With JX-8v, users can send and receive System Exclusive (Sysex) messages, allowing for efficient transmission of snapshot data and preset management. This functionality ensures that all automatic controllers maintain their current values, providing consistency in sound control during performances or studio sessions. The plug-in also allows switching between transmission and receipt modes, offering full bidirectional communication with the synthesizer.

The interface includes a dedicated presets panel where users can manage synth presets by sending Sysex instructions to switch or store patches within the internal memory of the JX-8p. Additional features include the ability to show MIDI Control Change (CC) messages, providing transparency and control over MIDI signals. Overall, JX-8v enhances the usability and functionality of classic Roland synthesizers within modern digital setups.
