One of the best things about buying tracks from this site is that it is easy to adjust the track speed without altering the pitch of the recordings, giving you a much greater flexibility in your practise.
By purchasing a recommended piece of software called The Amazing Slow Downer, you can create and save lots of different versions of any track you choose, either in MP3 or CD format. Therefore if I have recorded the tracks too quickly or slowly for your liking, you can use this program to adjust the tempo and save a series of versions at different speeds, with the pitch always staying the same. You can even select certain sections of the tracks to slow down and loop for practice purposes.
The program costs of $50 / (£25 or 32 Euros) and is available to download from the website www.ronimusic.com. There is even a free trial version you can download first to test out its capabilities.
