SyndtSphere may be just about the most flexible music instrument ever. It is also an iPad app. Klevgränd’s SyndtSphere can be a piano, a violin, a flute, a bass, but it can also be anything in-between. If you ever struggled to find the exact sound you wanted out of a synthesizer, then should try SyndtSphere, because you’ll probably find it there.
This iPad synthesizer lets you play almost any sound
