Very happy. Now I wish I (or someone I knew) had access to the rest of the gear. Clearly, I'm missing "Rob's part" as well.
For the tempo mapping, I've done it for various tracks so I reckon I got pretty good/quick at it - it took me around 3.5 hours, started as soon as I heard about the sysex dump.
The pattern changes took 10-14 hours on and off; lots of starting/stopping, muting/unmuting between the recording, MD and MM; placing markers on Reaper etc. Plus it's 127 patterns, most of them having very subtle changes, so really tricky and it's obviously not 100% precise but quite close.
