Thanks Yorgos I had already gone through the steps on your video (which is kind of why i posted the question here as well as on the abelton forums) thankyou for making it!
Ok so i've had some really weird issues that thankfully i have now managed to solve (it was kind of frustrating as hell!!!)
First my added latency issue came from the Saffire Mix software changing from Zero Latency Tracking to Mixing mode so I managed to solve that one.
Then I once again got everything sync'd up fairly easily and manged to get recording with an extremely tight sync i was so happy, unforunetly then more problems began, i started to run midi to my Tempest and everytime i recorded it the audio would be recored like 1/6th of a bar late, it seemed like the midi trigger kept its time but somehow the recording was just off by A LOT, i tried loads of things using the track delay being one, I wanted to keep the sync because it was so tight, eventually i found everything worked if i didn't use the EXT instrument and just ran a midi channel straight out to my Tempest, I don't know why but then it was perfect, the sync remained and the midi notes were sent out at the right time and recorded perfectly!!!
So thanks again Yorgos as i did review your video once more to see if i was missing anything.
If anyone else is having these problems maybe just do this old skool and run a channel without the EXT instrument as it seemed to add more trouble than it fixed....
