I have A LOT of TT Products -- Easydrummer expansions, midiexpansions, EXmixexpansions, etc, etc.
It would take a whole evening to register them all. That´s not rational, really.
TT -- please consider a registration system like the one XLN Audio has, which automatically updates and registers every product you have.
That is, in fact, a VERY TIMESAVING and COMPETITIVE functionality, and I hope TT takes note of that.
