    Great 303 sound. RD3 is a little too simple. I would pay a couple bucks for an upgrade to RD4 but will not buy it for full price. They are loosing money for not giving a discount to RD3 users.

    Before the Jun 26 update it was just kind of aright. A solid drum machine+303 app but really didn't bring anything to the table and could be criticized for being overly basic. But this update really made it worthwhile. Individual effects routing and 2 basslines at the same time. Really if you want a solid 303 and drum machine combo this is the cleanest solution to that.
