My bad :)

anyway, it should work as a remote control for the tempo, while
assigning a CC to Qtractor's tempo won't be that good, regarding to one
data byte = 128 values only. OTOH if more people would like to have such
a feature, it wouldn't be impossible to increment or decrement the
song's predefined BPM up to 64 values, ignoring the decimal digit for
the BPM.
