Got my hands on a Seqtrak when I was already looking to pick up an old QY Box. I waited a little bit before I made the purchase and also passed on the EP-133. The Seqtrak just seemed more my type regardless of no sample chop. It has a little learning curve but gets around better than a 404 mkII. Here's my first Jam so you better like and subscribe if you haven't already. Show a little Luv at least.
