Mark, that seems to work OK but I had other problems so I just started another project. Thanks for all the suggestions from you.

Absolute vs. Musical timebase  and Time Format settings of only affect the start times of MIDI clips; the timing and duration of events within the clip will still follow project tempo, even if the start time is locked to Absolute/SMPTE time.
 
The easiest way to change the tempo of a MIDI clip is simply to change it's length, either by using Process > Length or slip-stretching by holding Ctrl+Shift as you drag the end of the clip to the appropriate length (i.e. the same percentage as the tempo change/difference ratio).

HI:)
 
+1 brundlefly, that's what I wanted to answer, just Ctrl+Shift + Mouse!

Yes, my bad - you're correct.
 
It's a pity locking the position & data doesn't actually lock it at all :(
