Nice work on this one. Plenty variation, I didn't get bored. Really reminds me of some future bass on Monstercat, except it's a chiptune. All of the synths are pretty nice.
This is very nice, very nice. I think it might need one or two more instruments, as it sounds a bit too empty at parts, but a great start.
Please contact me if you would like to use this in a project. We can discuss the details.
