Hi,

I've tried to make a patch to detect audio tempo and convert it to a midi cc value that is sent to Qlight controller midi input.

Qlight controller is a great software for lightings, but it lacks audio-to-light features yet. But as it's possible to send midi values to control sliders (those sliders can be assigned to different kinds of parameters, here I use it to control the timing of a chaser, with min. value 0sec and max value 1second)

Here the result of my experiences: 4 different versions of audio analysis, + 1 with fix BPM value using a bpm2msec converter patch I've found here ;.)

These are very basic as I'm still a pure-data noob, so if someone is interested to help refine the audio input part, this would be much appreciated (as much on the analysis part as on the ui/settings part).

Thanks for reading

PS: also in my case it would be even better if the chaser steps could be triggered by midi event instead of having a timing value, but this can't be done currently with available controls in QLC, so I've made a feature request to QLC dev and hope it gets attention…

Hi Shawn,
aubiotempo is part of the aubio library : http://wiki.puredata.info/en/Category:aubio
In ubuntu, I've installed this pd object with pd-aubio package (and added it manually in pdextended path and startup settings).

I think I've read somewhere that those aubio objects are planned to be included directly in pd-extended, can someone confirm this?
