To me it is apparent that the user testing associated with this device was only done by persons either involved in production of the product or musicians.
To qualify this; Im an adult, I have a background in New Media and Production and have never had the opportunity to learn music and thought this would be a good method as a beginner.
I can deal with the keyboard being a bit small. I can deal with sound only coming out of the idevice you plug in. I cannot silently cope with poor user testing. The interface is perfectly simple and visually appealing, easy to navigate and intuitive but the video functionality is very flawed.
You cannot loop any individual section of a video or sheet music, any attempt to skip ahead/fast forward results in the video restarting. It is painful enough that Im considering whether or not to return the product.
In an effort to get around the video functionality issues I attempted to take refuge in the sheet music section only to be frustated by the same playback control issues and added logistic gaps. As before you can only play/pause with the addition of being able to change the beats per minute. As the play head walks through the music the keyboard lights up. That sounds good but the gap comes in here as you have no idea (1)what hand positions to take, (2)have no idea whether that note is an A, C, F or D as it flys past you unlabelled in the "beginner" sheet music. Perhaps an optional (toggle on/off) voice over to sing you what note letter youre playing could be helpful for you internalize some actual information. Perhaps an added learning section focused on sight recognition of notes within the staff so that when you visit the sheet music section it can eventually mean something/equate to notes to play.
ION has created an awesome tool for learning in this keyboard but rendered it useless as an educating tool with this app. I will only find value in this keyboard purchase if it interfaces with other synth apps my musician significant other uses.
In this current version - skip it.
