Problems in Mavericks

This app works fine for me in OS7, but unfortunately, does not behave with Maverics. Multiple hangs, stops responding, won’t export, frozen controls, etc. Needs work. It is what it is for a $10 step-imput drum machine. This is a standalone app, not an Audio Unit or VST, so it will not open in Logic or other DAWs. What I would like to see that as an improvment, as well as the addition of swing, as exported patterns (if you could export them) would have some groove, and be more real world useful. (Mav’s 10.9.4, late 2012 iMac 2.9 ghz, 8 GB ram).
