unlike drawing a curve you can instead have a so called tempo-map. however tempo changes can only occur at bar locations (as against to beats as it appears in your attached picture).
re. about VST instruments?
yes, absolutely! you can have VSTi plugins in either of the two supported flavors: Windows VSTi (*.dll) via DSSI-VST / Wine(-32bit only afaict.), scanned as "DSSI" plugin type or native Linux VSTi (*.so) then scanned as nominal "VST" plugin type.
hth.
cheers
ps. I too was a proud Cakewalk (Pro Audio series) user once, during the late years of the late XX century--you can tell that's obvious by the way qtractor looks which is still a founding reference ;)
welcome aboard.
