Topic: Loop BPM
Let’s say I manually set a loop, and then set that as a saved loop , will VDJ give me the BPM of the loop??

In this video they show SDJ and I would love for VDJ to do the samething if it doesn’t already??

Jump to the 12:35 mark

So it is calculable, but you have to have the machine assume the length of the sample in beats and to make sense with looping that's probably going to be 2 or 4, maybe 1.

set $choppedBPM2Beat `param_multiply "param_multiply 60000 'get_pitch_value & param_multiply 0.01 & param_1_x'" "param_add 'get_loop_in_time & param_invert' get_loop_out_time & param_1_x" & param_multiply 2`

That seems accurate to get the bpm of a loop, that last param_multiply is how many beats you'll be looping it into,

so then it's about getting that value to the other deck pitch, assuming just 2 decks.

set_deck `get_deck param_mod 2 & param_add 1` & get_var $choppedBPM2Beat & param_cast beats & pitch

In theory the fluid bpm could be put to use here, but I just can't get on with it


Whole thing as a custom_button

set $choppedBPM2Beat `param_multiply "param_multiply 60000 'get_pitch_value & param_multiply 0.01 & param_1_x'" "param_add 'get_loop_in_time & param_invert' get_loop_out_time & param_1_x" & param_multiply 2` & set_deck `get_deck param_mod 2 & param_add 1` & get_var $choppedBPM2Beat & param_cast beats & pitch

you could probably save the value to the loop name
 
Ok I put it on a custom button and have set my loop then saved and used the script as the name. I pressed the custom button and bring in my other track but nothing happens??

What am I doing wrong??
 
Not sure, dvs?, you're in the loop you press the button and the other bpm doesn't change?
 
Ok so I switched to the default skin (I use Phantoms GTS skin) and the button worked.

It kinda does what I want but Id rather have the BPM show as Im making the loop. With the button I have to set it and then play and then press the custom button to get the BPM.

A lot of button pressing lol!

Maybe this is a feature for a future update....

Thanks for checking it out LOCO 🙏🏾
 
phantoms skin must be deck master custom buttons,
you could use the custom button names as a visual so use these as 2 custom_button names

`deck 1 param_multiply 60000 "param_add 'get_time loopin elapsed & param_invert' 'get_time loopout elapsed' & param_1_x" & param_multiply 2`

`deck 2 param_multiply 60000 "param_add 'get_time loopin elapsed & param_invert' 'get_time loopout elapsed' & param_1_x" & param_multiply 2`
