Audio feedback during rhythm input
I find rhythm input -> repitch notes an amazingly fast and easy method for transcribing already existent sheets. But IMHO there is a little drawback: a little error can easily go unnoticed (the eyes are on the music) and require the rewriting of a chunk of music. Denemo solves this problem playing a percussion sound in the first beat of each bar. The -very- few times I used Denemo I always found that little aural feedback very useful.
