Well, this is a bit of a shameless self promotion but I'm pretty proud of my work so... meh! :D
I made this a little while ago, basically it's the "Gruntilda's Lair" theme from Banjo-Kazooie with all the instruments done on my keyboard. I intend to make more of these when I get the time (and potentially a better keyboard with an SD card slot).
Anyway, without any further ado... enjoy! And leave me a video comment...? :)
If someone knows how to embed a video I can do that too... I tried copy+pasting the iframe code but apparently that does not work here.
