There are excellent commercial music notation packages. Some are even able to handle tablature. But since electric guitarists outnumber us by at least two orders of magnitude, most programs tend to focus on that market.
There are many free and low cost editors for historic tablature. Most of them can do a very decent work for many kinds of lute and vihuela. However, when it comes to Baroque guitar, there are many features which would be nice. Alfabeto chords, little marks showing which way you should strum your chords... a better way to mix rasgueado and punteado... well you know what I mean.
What is your experience with each editor? Do you have any tips to share with us?
