The current version is now much improved, but its many useful features are not always immediately apparent.

Some tradeoffs have been made to improve speed and accuracy; e.g. in some cases one can only edit one "voice" at a time. But if you are only looking for a quick way to convert your musical doodles into something resembling normal notation, you are missing the point of this fascinating creative playground.
