Great sister synth to Laplace

I return to this synthesizer app, regularly, because it does what music apps are supposed to do, a unique sound with a simple interface. Laplace is my favorite of the ice works apps, but this is a great companion/expansion to Laplace, especially for the billed use, tuned percussion. I do like Laplace better for strings and plucks and keys. This one is really fun to play with a drum pad midi controller (tuned to a scale, if you like) for marimba, and bell like sounds.

Great synth!

One of my favorite iOS synths. Being able to import third party sounds, along with the included great sounds, really sets this apart from other iOS offerings. The best part of this synth, however, is how responsiveness of the developer! Bugs are squashed very quickly with timely updates. Must buy!
