The Elements Brain V2 from Livid Instruments allows you to create your own MIDI controller. You can connect up to 128 buttons, 192 LEDS, and 64 analog controls, connected via ribbon cables. It consists of the main Brain circuit board used in Brain V1 and an accompanying BusBoard board. It has been completely redesigned to provide an Easy Method (ribbon cable connections) way to build your own controller with the Omni Board (sold separately) and connectivity for totally customized setups using the Advanced Method (direct connect wiring). Brain V2 supports faders, rotary potentiometers, arcade buttons, rubber buttons, LEDs, RGB LEDs, LED rings, encoders, velocity sensitive pads, accelerometers, and more.
The Brain V2 BusBoard is the main board for Builder v2. The BusBoard extends the Brain by making the Brain’s capabilities of 128 buttons (or 63 encoders), 192 bright LEDs, and 64 (63 active analog inputs/ 1 ground reference) analog connections more accessible. In addition to easy ribbon cable connections, there are direct connections for LED outputs and button inputs.
Populated with many of the necessary chips and components, the BusBoard expands your DIY controller’s possibilities. When used in combination with the Omni Board, connections are made with 10-pin ribbon cables to carry Button, Analog, and LED control data. The BusBoard easily connects to the Brain by sandwiching to the main Brain board with female socket connectors.
The Brain uses USB for both power and communication, and a 5VDC power supply (sold separately) for standalone MIDI operation when not connected to a computer. It does not require any configuration when using LEDs, switches, and analog controls. However, all unused analog connections do need to be grounded with the supplied analog ground headers.
Brain V2 supports many ways to interpret analog signals. This is useful for integrating FSRs, potentiometers, accelerometers, and other controls into your setup. It also allows analog controls to send individually mappable Note On and Note Off messages when they leave and return to the 0 state.
Brain V2 also supports LED grouping. This is useful for things like making LED rings for encoders like the ones on the code controller. It can also be used with rotary and slide pots to show the current values or with FSR/s to represent velocity.
If you are using encoders, velocity sensitive pads (FSR), or LED groups, you will need to configure them using the Brain V2 Configure application (downloadable from Livid's website). This application can also be used to edit the default MIDI mappings of the Brain.
To see how many controls your Brain v2 can fit, take a look at the Brain v2 Hardware Calculator. Currently, Analog ID 63 (Pin Header: A8, Pin: 10) is used by the firmware as a reference ground. For optimal operation of the A/D Converter, this analog signal must currently be connected to ground (and not an analog device).
