Touch Pianist – Tap in Rhythm and Perform Your Favourite Music 11 years ago
Even for a rhythm trainer it is disappointing because you're forced to tap at a set interval, not what the notes are actually saying. And forget double-tapping when there are two notes on a single interval -- that just plays two intervals!
Thumbs down from a lifelong DDRer and casual pianist.
Though idank's comment is nice to see!
