I am attempting to figure out how to do "sound triggered" light chases. We have BPM, which is hard to get accurate. We also have "beat" which seems to trigger on a single push of the button, which can be triggered by a midi note on an external controller. I see "beat" can be triggered by virtual DJ also. Since I have no say so in the DJ's choice of software, I need to find another way to reliably trigger "beat"
Is there a way to utilize the computer (windows) onboard mic as a sound trigger for "beat", or is there a way to get the output from the DJ board into the computer, perhaps from a secondary output, or record output form the DJ board into a USB device of some sort? Or perhaps another way you all have figured out that I have not thought of

Thank you very much!
