Trying to remember this website..
I recently got back into playing, and there was a website I had used once which I can't quite remember, so I will describe it and hope one of you can help me remember.
The site layout was simple, I think it just had a white background, and a navigation bar on the left. The distinguishing feature I remember is the site had an interactive sheet music player. I think it was GhostScript or some other format, but it required you to download a certain program to be able to play the stuff in the website.
It was kinda like guitar pro, except it was free and built into the website. You could click on the location of the sheet music and play it at any given space, as well as slow it down or speed it up.
If anyone can think of a site that describes this please let me know! It had some great exercises on it for finger strength and warming up. In the meantime I am going to go through my old bookmarks and see if i can find it!
