Elastic Drums Universal price will be $11. The Update (end of march) will be free for iPhone app owners. So buy it now to get it cheaper :)— Elastic Drums (@magnum38) March 17, 2015
Elastic Drums is currently $7.99 and is one of the best drum synths on the app store. It's well worth taking a look at, and if you don't have it already, you should really consider getting it as the price goes up when it goes universal at the end of the month.
