Guitar and Drum trainer is software with multiple features. First of all, it lets you change the tempo of any song without altering its pitch. This feature lets you hear any instrument as was originally recorded, but as slower as you need so you can figure out easily the chords and master its rhythm. Also, the program lets you change the pitch of a song or musical piece in increments of one semitone. This way, you can transpose any song to virtually any tone that suits your needs. For example, if a song is sung in A but you voice tone is D, you can change the song's pitch to that tone. Both tempo- and pitch-changing features work independently from one another.
Also, the program lets you mute the central (voice) channel so it can be used for making Karaoke files. You can even edit the song and make loops on it.
Last but not least, the program lets you save your modified files and features an useful daily tip at startup.
If you are a singer, musician or even a dancer, this software would make easier for you to learn, practice and transpose any song or musical piece. The trial version is fully functional during 15 days. After that time, you must purchase a license.
