The samples choices are fine imo but you could use some better adsr. Like the @3's having a longer rest so they don't go out to quick, or the @0 having a shorter decay and a bit harder on the attack. I also don't hear any notice in the echo, it's almost none existent. If you're going for a bit of a reverb feel, the echo volume should be a little louder bc when I first heard it through the site's player, that was one of my first thoughts is that it needs a bit of echo only to see a has a delay of $05 lol. Anyways, it's not a rejection but it could be still use some polish. Hope to see an update soon! Quick note as well, please refrain from using tags outside of the official tags list.
