I know that iReal Pro was designed for instruction rather than performance.
But like many wonderful inventions originally intended for limited use, its genius has contributed to its outgrowing its original purpose. Toys have oftimes become tools. Rockets, for example.
Of course we'll always be asking that it do more, since it's not just a notation app, but one that sounds so good that we can't help but hope that it could get a little closer to the nuanced needs of accurate musical accompaniment.
As it is, it's almost unbelievable wonderful, and the price is ridiculously low. Yet I for one would be glad to pay much more for a few of the suggested features people have said they would like.
We'll just have to wait and see if the developers are interested in creating an iReal Super Pro. Either they or someone else is bound to do so eventually.
Cheers,
Jer
