Our EXPO Projects

Physical Setup

> Take the Theremin Base out of the box, and set it on a table near power.

> Place the Tower Camera in the green triangle base, with the camera front facing away from the camera embedded in the base.

> The Theremin Screen has velcro on the bottom to be attached to the Theremin Base.

In the Theremin box should be these things:

• Theremin Base

• Theremin Screen

• Tower Camera

• Spare Ethernet Cable + USB Adapter

• Spare Keyboard

• Audio Cables

Program Setup

**The password and username for the Theremin's computer are on a sticker on the computer, they should only be needed for debugging

> When the Theremin boots up, the desktop menu should look like (Image 1).*

* If it doesn't, turn to the troubleshooting section

Cardinal Setup

> Open the blue File directory in the taskbar

> Open the Home directory in Files

> Open the "Cardinal" folder, and open the program CardinalJACK for later

Theremin Program

> Use the dash and two dots at the top left corner of the screen/the windows key to return to the desktop view.

> Open Files > Home > Theremin

> In the Theremin folder, hover over any empty space and hold to open a small menu (Image 2)

> Select "Open in terminal"

This should open a terminal with the directory of the username + Theremin (folder).

> Either type "source .venc/bin/activate" into the command line, or use the up arrow key to find it in recent usages, and click enter

> Then type "python ui.py" into the command line, or use the up arrow key to find it in recent usages, and click enter

This will open the Theremin Program.

> Click the Refresh button at the bottom and the drop down menus should fill in

> Keep the camera on the right as is, use the left dropdown menu to switch the Tower camera* to the second option in the drop down, and click apply

*If you apply these incorrectly, you will need to restart the software.

> Click "Start Tracking" at the top, and the camera feeds should appear

QJackCtl/Patch Board

> Use the dash and two dots at the top left corner of the screen/the windows key to return to the desktop view.

> Click the 9 dot grid in the taskbar, and open the "QJackCtl" program

> Click the "Graph" button in QJackCtl, and a Patch Board should appear (Image 3)

> From the “Midi-Bridge” input on the left, drag the bottom most red option and drag it to “events-in” in the center block

> Drag “audio_out_1” to “playback_FL” in the “AC511 Sound Bar Digital Stereo” block

> Drag “audio_out_2” to “plackback_FR” in the same place

CardinalJACK Usage 

> At the top menu, go to File > Open > Home > Theremin > Patches, and select any of the Patches (different effects)  in the folder (We usually use the Spacey one)

This will change the layout of the board.

> Find a red glowing button, possibly labelled mute (depending on the patch used) and click it to unmute.

> There should be a Dim button or slider if it is too loud

> Scroll all the way to the left and find the "Cardinal Host MIDI CC" block

> Make sure that the inside of the input wires turns green when a hand is detected by the Theremin Program
