Practice# is a tool for practicing playing an instrument with playback music. It will turn your playing skills sharper! MP3, WAV, WMA, Ogg Vorbis and FLAC playback. Speed change - The ability to slow down or speed up music without changing its pitch. Pitch change - The ability to change the pitch of music up or down without changing its speed. Loops - Start and End Marker with Cue (waiting a few seconds before the loop starts, useful to get hands back into position). Persistent Preset Buttons - The biggest difference currently between Practice# and the other tools out there. In fact, that is why this tool was written by me in the first place.
