Plug one end of the USB cable into the Trigger Finger and the other end into a computer. Turn the computer and Trigger Finger on to automatically install any required drivers.
Double click the desktop shortcut for Ableton Live. Open a desired project when prompted on startup, and create a new MIDI track by clicking "New Track" from the "Create" menu at the top of the screen.
Click the "Window" menu at the top of the screen and selecting "Mixer." Locate the newly created track. Under the "MIDI From" box under the track, click and select the "Trigger Finger." Ableton now takes data from the device and inputs it to the sequencer.
