In response to the growing demand for more 'musical' and more 'hands-on' controllers for laptop performance, STEIM has created junXion, a software application for music performers, art installation makers, theater makers, choreographers.

junXion v2 is a Mac OSX data routing application that can process any Human Interface Device (joysticks, mice, touchscreens) and MIDI device data using conditional processing and remapping, with MIDI events as its output. This resulting MIDI data is then available to any audio or music software that runs on that Mac or can be send to external MIDI devices.

junXion v2 is redesigned completely from the ground up (as compared to v1.4), resulting in a system whereby the user creates so-called 'Patches'. Each Patch is a connection between a sensor input (for example: 'joystick X-axis') and an Action (for example: 'convert the sensor data into midi controller 3, but only under certain conditions'). The Action is a user selectable set of conditions and actions that determine what should happen with the input-sensor's data and what kind of MIDI data should be send out.
