syncing midi to ADDA ?

[nebelfuerst]

I use SamX3 and a - self written - midi sequencer.

SamX3 is Adat-Slave to Xite.
SamX3 also generates a MidiClk to my sequencer.
SamX3 records the synths steered by the sequencer.

After 20min of running a testpattern, there is slight deviation between several takes.
Obviously SamX3 doesn't sync the Clock to Adat perfectly.

Is there a way to use scope to provide a ADDA-synced midiclock ?
( I think the vintage trippledat could do.. but I don't want to rely on vintage ISAcards.)
