Right, I've got the full version now. I've worked it out, if I have anything which is outputting sound open, (even YouTube) then Massive won't output anything, so I have to close down pretty much everything and just use Massive. I made myself a synth then installed the Massive plug-in too FL Studio. I don't have a MIDI controller so I was using my keys on my computer keyboard to listen to the notes but now when I open up Massive in FL Studio they don't produce sound and even the sound levels don't go up.. Whats happening? Do I need a MIDI controller?
