pretty much a winning combination for me +)
i didnt experience (or hear) any timing issues - felt pretty solid to me). my OT is the master and in the beginning I had the OT send program changes too which is cool when using the arranging mode as you only have to worry about it on one end (OT)…
but I ended up having the MD only tempo and transport slaved to the OT. And then, depending on the needs either just a through machine or 2 more tracks with dedicated recorders… recently I ended up only recording phrases into the OT, switch off the MD and then take it from there… but I’m pretty early stages figuring out my personal ‘workflow’ (no work or flow present yet) - the latter method felt pretty natural tho as it made me focus more on one thing
