Get ready for the newest internet sensation: Red Bull Xtreme Sight Reading
A recent Ask Willis reader pointed out that the old version's lowest note was an F and I was neglecting to challenge those of us with more than 4 strings. So in making this new Xtreme version, the first thing I did was extend the possible range to a Low B. That makes for some wicked intervals so next I put in an adjustment for the top note. You can still do the crazy Xtreme interval thing by setting the high and low range from a high G to a low B, but make sure and wear protection.
Another new Xtreme feature is the ability to adjust the probability of accidentals. Sight reading never gave this kind of rush before.
