New to this machine.I have the preenfm2 hooked up to a computer via usb using the editor in REAPER, the midi out of my keyboard is going into the preen, and I have a midi cable going from the preen to my roland drum machine. I want the preen to control the drum machines tempo but it's not working. I know my drum machine is set up correctly to accept external clock because I can control it from multiple other devices. What settings do I need on the preen? Thanks, it is a great instrument so far.
