Do you speak midi, I sure don't. But... I am trying to integrate a Boss RC600 looper and an Arturia Astrolab keyboard with a Roland SP404 MKII for live performances. I want the SP404 to control/set the tempo for the two other instruments so that loops, effects and arpeggios are all synced together. If this sounds like a challenge you can solve let's talk. More than happy to compensate for your time.
