This is really an excellent app. It was amazingly easy to get running and was just what I wanted in order to use my MacBook Pro's keyboard as a midi controller for JeuxdorgMini (will be using other music apps in the future as well).

This app is truly great for producers on the go, especially when you don't want to drag around a huge MIDI keyboard with you everywhere. Pros:-You can have two rows of keys to use for the piano, each with separate octave as well as "first white key" control so it can be set up however you like, and allows for hand arrangements other than C position. -The "Chords" tab is probably the most interesting because it allows you to predefine chords and map them to numbers, so you can easily build a chord progression and play huge chords without being limited by the number of keys that you can press simultaneously on the keyboard. -For example, "1" could be mapped to a chord with up to seven notes in various octaves, and "2" could be mapped to more notes, then playing both simultaneously allows you to play enormous arrangements that wouldn't even be possible with two hands.-Allows you to use mouse and touchpad input and gestures to control the mod wheel, pitch bend and note velocityCons:-Haven't used it enough to discover very many, but there is no way to make it constantly override keyboard input, so if you were playing notes in an application that doesn't support keyboard MIDI input (Pro Tools!!) and you wanted to tweak your synthesizer's sound, you would have to switch applications back to Easy MIDI in order to test your changes.-In any case, this is something you would probably use a MIDI controller for, so it's not that big of a dealAll in all, this is a great tool for not just playing notes on the fly, but also for easily mapping and saving chord progressions, so you dont' have to export MIDI files between programs.

But it doesn’t make any sound. Tried deleting and reinstalling and it simply doesn’t make any sound.

I decided to take a chance with this app thinking I'd only lose 15 bucs if it didn't work out. WOW! It turned out to be a fantastic buy!I've able to compose on my mac keyboard using this app. Extremely useful when using BBC symphony app from Spitfire. It's enables you to use the full range of your Mac keyboard.
