Proceedings of the International Conference on New Interfaces for Musical Expression

This paper presents the JD-1, a digital controller for analog modular synthesizers. The JD-1 features a capacitive touch-sensing keyboard that responds to continuous variations in finger contact, high-accuracy polyphonic control-voltage outputs, a built-in sequencer, and digital interfaces for connection to MIDI and OSC devices. Design goals include interoperability with a wide range of synthesizers, very high-resolution pitch control, and intuitive control of the sequencer from the keyboard.
