I have tried a few solutions, and eventually used this piano keyboard for iOS, since I couldn't get rid of the lag which is crucial when using it as part of a multitracker for timing issues (an app I'm working on).

I learned a lot from going over the code and through the support I got from the author, so even though it wasn't free I was very pleased with it.
