BPM Trigger additionally to the speed trigger

[kroeder]

Next Feature Idea: a BPM Button which blocks the speed value
I'm pretty sure either minim or another library out there is able to check the current BPM of a song and then triggers the current effect per beat

This could be additionally to the speed trigger

1. Speed is more a blocker: a effect trigger only triggers within a time value calculated by speed + H/S/K/P
2. BPM triggers a effect by beat

I'm not sure how easy this is to implement, though
If the BPM Trigger also needs H/S/K/P or just triggers every beat etc.

Love the idea. But that would require getting music from a different source. You'd need to analyse the track in advance. I think this is gonna be very difficult.

The big parties i'm at in holland uses live analysing. When the beat stops, it usually takes a second or two before the lights decide to stop rocking it to the beat.

Wouldnt it be possible to use a buffer of audio in for, lets say 2 seconds and adjust the beat after those two seconds?

Hi @kragebein!
Just to understand you right? That is something you are experiencing with processional lighting software?

I think it should be possible to calculate the current BPM on the fly, but I haven't looked into the math behind that yet.

Correct! Like Defqon and Qlimax etc!

Another thing many lighting software decks use is manual tap BPM detection, should be easier to implement.
