It’s down from around £45 to £15 on Kindle at the moment. Probably since the info is out-of-date after the EX24 update. The Kindle app to read it on is free for Mac. I was a bit disappointed that the topics covered in the first book are all covered on Youtube, but it was still worth it for the lesson files. I’m hoping I won’t regret buying the Advanced book. Dunno if it will go into detail about the score editor but I hope it has a few extra tips.
