Hardware synths out of sync in Cubase 8.5

I am facing a problem with my outboard gear in Cubase 8.5 using RME Fireface soundcard.

For example i tried recording my Roland System-1m synth and i get different times on 3 different recordings.
Does anybody knows what could actually fix this problem?
On some forums mentioned is MOTU MIDI Express XT 128 8x8 MIDI Interface … Will this fix the problem or i should actually think on buying something like Expert Sleepers, Innerlock or E-RM devices?

Here is also a image in the attachment of the different recordings with same setting of the Roland System-1m

Any help will be highly appreciated.
