An older app that’s for sure, but still without a doubt one that is well worth digging in to. In fact, it did take me a while to get my head round how to use Jasuto, but once you have the basics it is very easy to experiment with and learn a lot about synthesis.
I’ve found it a great tool and very enjoyable. The only downside is that it has not been maintained for a long time now and I’ve not been able to contact the developer for ages. I really hope that this will be resolved in the not too distant future.
Even having said all of that, I still think that Jasuto and the Pro version is an amazing achievement on a mobile device, and I hope that one day we’ll see a new version that continues to amaze.
