I use BFD to tweak my kick drum samples and when I play on my Ekit for recording and demos.
Here is one of my band Dissolution's new songs that is 10 minutes long. It is an endurance test to play this with no breaks. I know death metal is not everyone's cup of tea but it sure is fun to play. It really picks up around the 2:45 point in tempo.
The audio is not CD quality, there are zero edits, and there are plenty of mistakes. I will be spending the next month ironing out the time changes, changing a few parts up and getting ready to record 7 brand new songs. I also chopped half my head off for some of the video when I bumped the camera, so lots of fails going on in this video haha. I might make another song soon to redeem this one. https://youtu.be/dBre0S0TsTU
