For my original music album “I Hear Your Signals” (download the album free) I use Percussa Audiocubes as performance controllers. In this post I’ll give you all the geeky details about how the controllers were applied in the project.

AUDIOCUBES AND MIDIBRIDGE
I used 4 AudioCubes plus Percussa’s free MIDIbridge app on Windows to configure and route AudioCube signals to Ableton Live. I use the same MIDIbridge patch for every song which allows for consistent and predictable data mapping from the cubes to Ableton Live.

In general, I play a lot of the notes on you hear on the album via keyboards, Theremin and Tenori-On live. I tend to use the cubes as controllers, for scene launching, and for real-time modulation of effects and synth parameters and only use them for triggering notes from time to time.

CUBE CONFIGURATION
The AudioCubes are configured with the in the following modes:

• Cube 1 – Sensor (the red cube at 9:00 in the picture above): This cube sends MIDI CC information back to Live. I configure each side of  cube to give me visual feedback where each cube face is set to a different color. The closer my finger or hand is to the sensor, the brighter the light. Currently, Sensor cubes need to be wired via USB.
• Cubes 2 & 3 Receivers (white cubes in above picture): Sends MIDI notes back to Live when a signal is received from Cube 4. I also send RGB MIDI light sequence via MIDI clips in Ableton. The cubes then become light show elements and also offer visual feedback. These cubes are also plugged in via USB so they can receive high-speed transmissions via MIDI clips.
• Cube 4 – Transmitter (green in the picture above): This cube is wireless. Aligning the faces of this cub with the faces on cubes 2 & 3 triggers MIDI notes back to Ableton Live.

MIDIBRIDGE AND ABLETON CONFIGURATION
I then MIDI map MIDI CC data and Note information coming from cubes via Ableton Live MIDI Map mode to various functions within live.
For cube 1, CC’s are mapped to device parameters and macros. These in-turn are often routed to parameters within VSTs. For example, a cube face might modulate delay time with Ableton’s native Ping Pong Delay FX device. Or the CC might map to filter on a VST synth. Below is a snapshot of the MIDIBridge settings for Cube 1 (click to enlarge).

For Cubes 2 & 3, notes are triggered when the face from the transmitter Cube 4 is detected. I route notes to either MIDI tracks holding Ableton instruments or VSTs and/or racks. In some cases I route MIDI notes through a dummy track back to SugarBytes Artillery II running in a send or on the master track for effects. Since effects are triggered via notes rather than CCs with Artillery II, this method allows me to control effects as well as playing notes with signals from Transmitter cubes which only send MIDI note information. In other words, by combining native Ableton effects with Artillery II, I can use any cube in the network to trigger effects.

CUBE USAGE FOR EACH SONG

1) “Arrival”

In this song I’m using AudioCubes as lighting and feedback elements in the live show. They were not used in composition or performance of the music. MIDI clips in Live are used to sequence the lights.
