I have my PF set up as the master MIDI clock in my effects chain. Along with the PF, my MIDI chain includes a Line 6 M13 and a Yamaha drum machine. I have the MIDI chain set up so when I step on a foot switch on my M13, it changes presets on my PF. This part is working great. The problem is that the PF does not appear to transmit the new MIDI clock setting because my drum machine does not change tempo. But when I use the Tap Tempo foot switch on the PF to change tempo, the tempo changes correctly on the drum machine. I have checked and rechecked my settings and I think I have everything set up according the the manual. Is this functioning as designed or am I doing something wrong?
