Yes it will cost a fair amount of money (that seems to be worth it though) but there is good news for us poor souls and that is that there will be a Android application that is meant to go with the hardware but after speaking to one of the developers he sent me the info and it looks like a nice virtual instrument just on it's own.
The Oval App is still in development. But I can tell you what is the Oval App now and what is going to be in for sure.
The Oval App has several sound sets and scales, hang sounds, percusive sounds and some other sounds, at the moment we have a sitar and several fx/pad sounds.
The Oval App allows to apply effects like delay to the sounds played.
The Oval App will have a four track looper to loop the notes played with the Oval.
We are working to allow the user to upload their own sounds.
The Oval App for iOS will be the first to incorporate Bluettoth connectivity with the Oval. We are working to integrate this capability in Oval App for Android too.
The Oval App will be usable without the Oval, but that makes sense only to prepare settings to play the Oval as the Oval App will lack the sensitivity to pressure and velocity and neither the ample space to develop the body gesture way to play the Oval.
