I pulled out my Alesis HR-16 drum machine and verified that a 120 BPM
setting produced 250 mS clocks from the MOTM-650 while the internal
clock generates 125 mS clocks. I've now verified equal results with
two different external midi clock sources. I get 1/2 the clock rate
with an external midi source when compared to the internal clock. I
believe the internal clock is correct and the external midi clock is
divided too low.
I also verified the ArpClkDv setting has no affect on the clock
output as I would have expected.
