Oh bugger, what version of Firefox and OS are you using? I admit I only built it with Chrome but I did test it last night on Firefox osx and it was working ok.
I'm looking into bpm detection and cue points are on each player (they just might be hidden on a small screen). Will look into key and dragging the waveform.
There was a nice article on the beatport tech blog. I didn't manage to find it when I searched yesterday. Basically what they suggested was applying a low pass filter to isolate the base drums, then count the most common intervals between peaks (basically some kind of transformation) and then reconstruct the BPM from there by applying a range from 80-160 or similar. Hope this gives you a rough idea.
I implemented and tested it and it worked quite well with electronic music.
Works pretty well but requires to upload a file, then process it to get the BPM. So you would need smaller audio samples as the soundcloud stream is too big and takes ages.
I don't know how often the data is present, let alone correct, but iirc the SoundCloud API lists bpm as a field in the track data. Might be worth a look if you haven't already.
amazing work, I loved playing with it. I'm a DJ nub tho :( would be really cool to have a very quick tooltip getting started mixing the first song kind of thing
this is pretty great man! i've been playing with it for a couple hours now. my only complaint is that it's pretty hard to time the drop since there seems to be some lag between when i click and when the track starts playing (could just be my computer though).
Very cool! I hacked the exact same thing a while ago. Also with soundcloud integration (and some filters and stuff). I'll take a peek at the code when i get to my computer in the next days. Maybe there is something where i could contribute.

Thanks for the feedback.

(no longer on the beatport site; tech.beatport doesn't seem to exist any more and the current beatport blog starts at 2015)
I wanted to try it with another transformation to see if it can achieve better results.

Here is the link to what I hacked back then: https://github.com/letier/boombox
I'm planning on doing a complete rewrite, when I finally find the time. This thing was build pretty quickly.
Yeah, sorry the repo is private until I get it cleaned up a bit. This has been built quite quickly as well ;)
