DP-008-EX to Reaper latency issue

Hi folks,

I have finally added Reaper to my workflow. Although it seems great, and I understand it will take time to find my way around it, I've hit an immediate barrier...

I've imported all 8 tracks of a song from my DP-008-EX into Reaper. They're all appearing fine and all set to a starting point of 0. When I play them back together though, there's terrible latency between the instruments and the vocals (possibly about a delay of a second on the vocals).

I've done some research and the driver has been mentioned as a possible reason (but I don't want to fork out for ASIO).

Is this something anyone has experienced before? I'm really hoping there's a quick fix.

Its not clear to me what your problem is. Are the 8 tracks not in time between themselves, or is there a discrepancy between the 8 imported tracks and a new track being recorded in Reaper?
Or are you playing tracks from Reaper into the DP-008 with new recordings on that machine?

Supposed you exported the tracks from DP8 into its wave folder and you copied them over to the computer, first thing to check: are they in sync over the 8 original tracks just pöaying back?
If ok does the problem manifest already after import in Reaper?
If still ok: does the problem become evident after processing the files in Reaper?

Yes, please say if the vocals are one of the original 8 tracks imported from the DP-08ex, or are the latent vocals being recorded to Reaper as those original 8 tracks play back.
