A New Path - Venturesome Fun

As a classical pianist and jammin synthesist, this iOS app enthralls me as its takes "Core Audio", the professional quality of OS power, and audio frameworks come to life for a plethora of sounds. What is cool here is a solid foundation building on a vision.

What's unfortunate is that it crashes iOS 8.1.3 in an iPad 2, while 2 dozen+ other synth apps don't. The other eye opener is the classic "freemium" model. One can make sounds and play midi input with the free version (only available one), but has to pay a $0.99 "pro fee" to get to what others rave about and anyone would want to use.

These two items made me turn off iPhone apps on my iPad (still sold and supported for iOS 8). It also made me wary of what it might do to my iPhone. I don't want to use a review as a bug report, but encourage the creative and earnest developers to ensure it's a hit everywhere so music apps like this thrive and inspire more. Take advantage of buffer sharing and connecting apps, like AudioCopy.

Looking forward! Four stars to 5.

I love it!!!!!

Please don't ever change it but leave this like this forever. It's the best thing to use. I love this app. Just leave this the way it is do not upgrade this app. It is beautiful.

Terrible latency issues

Takes at least a second to respond, if it responds at all. Could be a decent app if not for this glaring flaw.
