RC-50 tempo sync issues via MIDI clock

["John K." <raisinhill@gmail.com>]

Hi Guys,

I wanted to see if anyone had any ideas on this RC-50 issue..

I'm a guitarist trying to sync my RC-50 pedal and loops to an
electronic drummer I've been jamming with.  He's been providing me
with his MIDI clock tempo via the MIDI IN on my RC-50.

I finally figured out a way to get all three loops to obtain the same
global tempo and sync together by turning on the guide, but channeling
it to the unused Sub Output, so I don't have to hear it.

The issue I'm having, however, is that the tempo being received via
the MIDI clock from the drummer is always off by .2 or .4 BPM on the
RC-50.  .. For example:  if he sets his tempo to 140BPM, it will read
as 139.8BPM on my looper.  This seems to cause the loops I create to
slip out of time slowly over time.  Any ideas on how to resolve this?
Why did Roland even allow tempos beyond whole numbers?

Thanks for your help in advance!!
