Am I to assume that it decodes drum tablature into sheet music?  If so, very nice!

Unfortunately, it doesn't seem to solve the problem of an inaccurate tab.

The main benefits of tabs (IMO), are: 1) small file size, and (2) easy creation via any basic text editor.

Most of the transcriptions I've seen online come in PDF format.  While they're not huge file, the difference is definitely noticeable by modem users.  Additionally, the only free PDF *creation* software I've seen is OpenOffice.  (While PDF readers are abailable for free, you need Adobe Acrobat or a recent MS Office, or other commercial alternative).

Tabs also are waaaaay more common.  The only decent collection of PDF transcriptions I've seen so far are at Chris McCaig's website.

(Coincidentally, I totally prefer transcriptions, and whenever I can't find one, I'll see if theres'a tab available, then convert it with a rather nifty piece of software called TabTrax, which I find works better than the other one postged above.  TabTrax isn't free, though...).

I didn't intend to say this should be a replacement for reading and writing music...rather it is a way to convert tabs (not musical notation) into actual sheet music which would mean you would be reading said music, and not a tab.

What I meant is it's easy download a tab, make any changes you believe should be there, and convert it to music for a nice printout/save to disk.  I don't know of a way to create sheet music for drums on a computer easier than this method.

For PC users, you can use this the same way:
Cute PDF

Free, easy to use, efficient... I use it to publish my own transcriptions on the web in PDF format.
