ouch! confirmed!

it seems to affect non-zero offset MIDI clips--the clip offset is not there being correctly converted to the new tempo, displacing or shifting the content forward...

will investigate deeper this annoying offset bug, which I think is a reprise from older days :/

thanks

UPDATE: maybe fixed in qtractor >= 1.5.3.19git.822c33; please test && tell.
