I’m really liking Renoise so far! Checked out the trial this week and ended up buying the full version after just a couple of hours of playing around.
My only tracker experience comes from LSDJ so I love the environment but am naturally a bit overwhelmed by the amount of plugins available at the moment! From the simplicity of 4 channels and limited capabilities of a Game Boy to an almost endless scope for creativity and professionalism is going to take a bit of getting used to. But hey, I wouldn’t have put down if I wasn’t willing to give it a shot. 
Finally, kudos to the devs for a/ making a great product and b/ making it affordable!
