Easy MIDI has been updated to v1.4.1. Here's what's new:
- Snow Leopard: the app launch crash bug fixed
Get the update from the Mac App Store.
There's a bug in Xcode 4.6 that causes Cocoa apps compiled with it to crash on launch on Snow Leopard. It only affects projects that use ARC technology. Developers, until Apple fixes this bug I recommend that you keep using Xcode 4.5.
