I've no idea how easy this is either to understand/visualise or implement.
If I record a live session's MIDI events, notes won't all start in perfect alignment, as you'd expect - that's why sequencers have a "humanise" function. This isn't what I'm talking about.
The other "error" humans make is speeding up and slowing down as the emotion of the tune takes them. The tempo of the piece changes.
Normally, once you've recorded a bunch of MIDI events, they're fixed relative to the MIDI time line -- not the time at which they originally occurred. So if you change the tempo, the events move.
The feature I'd like -- as an option -- is to have "grid fluidity": where changing the tempo leaves the events at their existing positions and only moves the "grid lines". Once the correct tempo change tracking has been achieved, you'd lock off and go back to normal, where changing tempo moved the events.
Does that make sense? I guess it's the MIDI equivalent of audio "time stretch".

As far as i understand you want to create a tempo track/sequence that matches the alive midi recording, right?

Yes - ideally visually aligning parts of the track's tempo to the actual recording.
