Connect a USB cable to the "USB Out" port on the Trigger Finger. Connect the other end of the USB cable to the USB port on your computer.
Open your preferred digital audio workstation, for example Reason, Ableton or Logic. The Trigger Finger is a flexible controller, but does not have sounds of its own. It sends MIDI messages to your digital audio workstation and tells it which drum sounds to produce and at what volume.
Open a MIDI channel in the digital audio workstation. The specific process for doing this varies slightly according to which program you use, but typically you click "File" and select "New Channel," then select MIDI when prompted. Because it is USB-powered, the Trigger Finger is universal. You don't need to assign it as the primary MIDI controller.
Assign a drum sound to the MIDI channel. Open the "Instruments" menu and scroll through the kits until you find one that you like. Leave it highlighted to assign it to the MIDI channel.
Press and hold the first drum pad on the Trigger Finger. Turn the "Prog/Bank" button to scroll the potential drum sounds assignable to the pad, based on the selected MIDI kit. Once you find the sound you want, for example "Kick Drum," tap the pad. Repeat this process for each of the 16 pads. If you are using Reason or Ableton Live, you'll notice that the Trigger Finger is pre-mapped, meaning the drums are automatically assigned to a pad. You can change this using the drum-assign process.
Click "Devices" or "Device Manager," depending on which program you are using. Select "Trigger Finger" from the drop-down menu.
Click "Preferences" and select "Parameters." This opens a list of parameters, such as "Volume," "Feedback" and "Filter."
Click on a parameter and select "Assign." From the drop-down menu, select one of the four slider dials as the controller for the selected parameter.
Hit the pads with your fingers and tweak the parameter slider dials to familiarize yourself with the layout and function of the Trigger Finger tool.
