I listened to the original and all i can say is that your version is accurate and apart from that just great as a loop, as a said the beat needs more work i can barely hear it, although you seem to be changing the beats we cannot hear them properly. :D
Yeah, I did not boost the beats up too much and that's a problem with hypersaw, even with volume lowered, it tends to drone out the beats. And it's quite near the original, I just added to the melody as I thought it should have gone aka: the end of :19, when that repeats, I went to a higher note, and then again...
Please contact me if you would like to use this in a project. We can discuss the details.
