BPM -> WLED effect speed #17

Should translate this to automatically set WLED speed

jwardle commented 2 years ago

Just Googled for this feature - would be great if BPM could be translated to effect speed when playing music. It would be useful also if this could be triggered on/off by certain presets, as one may not want BPM reactive patterns for all effects/presets.

I think it should be possible to do on a per-mode basis: set the speed to 128, time the "period" of the FX mode, then set to another speed & re-time. If the period changes proportionally, the effect is probably F(time) and could be mapped to a tempo. I've added a method in this branch to set the speed of a mode automatically based on the current tempo. But I don't have the appropriate timing factors measured yet so it's always setting to 128 ;(

of course, could also look at each mode's code to find its period :)
