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.

Core Synth does what it promises and reasonably over delivers. Great LFO, resolution, punch and arpeggio. Holds its own in probably most every context. When I get a little sketch in my head, I can punch it out in CS, rig the lightning port of my iPhones and connect to a laptop and enable it as an input in Audio/MIDI Set-up, choose that input from Ableton Live, play out the phrase and loop it or if I’ve made a righteous patch just sample the base note and compose in DAW.

I used a wireless speaker

Would work great if the audio clicking wasn’t there. just need something simple to do sub synth live at a youth event. Full version worth .99 but nothing more
