Yes, its all been synchronised with MIDI clock, when I change tempo on Rytm the tempo changes on A4 (A4 as slave) however the A4 is not keeping tempo, the tempo is changing very slightly going up and down by .1 when watching both at the same time the A4 is going quite a bit faster.
Also sometimes when pressing play on Rytm (master) the A4 skips to bar 2 without playing out the whole of the 1st bar?
Bear in mind this has all been working perfectly fine up until now
