Response from developer

Apparently you didn't actually read the description of the app before purchasing it. It specifically says that this app is just a MIDI controller for other iOS MIDI synth apps and doesn't make any sound on it's own.

Versatile MIDI Controller

I've been experimenting with this controller and it is opening up new creative possibilities more tan any controller I've ever used.
It especially shines on creating rich rhythmic patterns using Trilian and many other soft synths.
I find myself regularly tweaking the Transpose Semi-tones and velocity settings in order to find the right expression. Also combining multiple samples make this a controller that goes far beyond controlling the beautiful instrument it reflects.
Clearly a controller designed by a musician!

Love this developer

This midi controller helps me get things I haven't gotten out of other controllers. I like to use it for runs, staccato plucks, etc. works really good with more percussive sounds like harp, strings, etc.... Thnx!

Hey! Awesome MIDI controller

Thanks go out to Michael Eskin for creating this unique and awesome controller for MIDI apps. Try it, your apps will be played like you've never played them before. It's pretty cool!

Unique MIDI controller

As someone who doesn't play dulcimer, using this interface causes me to play notes that I wouldn't normally play on a standard piano keyboard. Using it as a MIDI controller results in unique melodies that change the whole dynamic of a song.

If you're looking for a "different" kind of MIDI controller, check this one out!
