How the USB Trigger helped Canadian broadcaster Don Andrews
In July 2011, Toronto broadcaster
Andrews contacted Sensorium Embedded via Paul at
PJRC. He was tired of
hacking mice and joysticks to connect to his radio station control panel
to give his on-line radio station a more professional feel. He's been
doing radio for 20+ years and wanted to see internet radio control
released from the world of keyboard shortcuts and hacked joysticks.
By using the USB Trigger, Don interfaced his full button console to his
Mac via a single USB connection. He then used
to turn the inputs into key combinations that run
MegaSeg Pro DJ and
Radio SW for Mac.
