This is a simple utility to help you test an 8 channel speaker setup in odd-even formation. This is an editable patch, so you can adjust parameters to fit your own needs. There is a speaker icon that functions as a button for each channel, and is not the usual DSP speaker icon. As a result, the file speaker.jpg needs to sit in the same directory as the Speaker Test patch. You can choose any frequency you want for the Sine wave input (default 440), and you can adjust volume to suit your needs.
