I'm considering buying volca beats to add some percussion parts to my guitar playing. Usually when I'm performing live I create audio loops with my looper - Digitech Jamman. It would be nice if I could create first a beat using volca, and than create a loop (volca, plus my guitar playing) in Jamman. But there is problem of synchronisation. The final loop (volca plus guitar) should has exactly the same length like volca beat. Is there any possibility that volca could control (sand some tempo information) the tempo in my Jamman? This is the model of Jamman I'm thinking about. It has something that is called rhythm out...

Or maybe opposite - Jamman could control tempo in volca?
Or maybe You could advice me any other looping machine which cooperates with volca. I just need one audio input in it. Actually two - one for guitar, and other for volca...

Thanks in advance!
