At the time of the 2014 giveaway, registration was offered on the Waves website at the link below. This historical promotion has ended, and the linked page was unavailable when checked: http://www.waves.com/lpn/black-friday/2014/free-pumper Thank you for your support.
I just got it too and have been trying it out. You uploaded the tutorial incredibly quickly!
If a particular kick sample did not give me the groove I wanted, I used to send a different kick sample via a pre-fader send. But it might be worth trying this plug-in first. This video went up quickly because I uploaded the recording without our usual editing. Now the biggest challenge left is writing tomorrow’s article (laughs).
