The Alchemy synth for iPad mini 2

Hello. I have a question about the garage band app. Why the Alchemy synth is not available on iPad mini 2 on iOS 12? I think that that iPad have enough power to support it. Cause in 2012 I had the iPhone 3GS and had the Alchemy synth app from camel audio and it worked. I really like the garage band app, but I have no MacBook, only iPad mini 2 and iPhone SE. I hope you will add the iPad mini 2 to “available list” of the Alchemy synth.
