Setup
1) Drag&Drop MIJOY PRO in the track view.
2) Set MIJOY PRO to MIDI Port Mode and choose the MIDI output port you want to use for controlling Live.
3) Never close the plug-in interface with the [x] button. Simply click on another track to make it disappear.
4) Load the VSTi / tracks you wish to control with MIJOY PRO and click the [IN] button under Monitor.

Note: In order to use MIJOY PRO in MIDI Port Mode you will need a virtual MIDI cable driver (like MIDI Maple) or a MIDI loop-back.
You can create it by connecting a physical MIDI Output of your MIDI interface to one of its MIDI inputs.

Using Multiple joysticks/joypads
1) Choose the appropriate joystick number under the Setup menu for each MIJOY PRO instance you have loaded.
2) Assign a different MIDI output port to each instance.
