Thanks a lot

Hey, I have a patch which is using a leap motion and pd and I can't for the life of me find the equation to create a bpm-synced delay patch. I know the equation conatins an expr message and it's something to do with dividing by 60000, but I can't figure out the exact way to do it and where to attach it to my delay. My delay is a vd~ by the way, hope someone can help. Cheers
