I have purchased some of these registrations with his keyboard books.
They are Yamaha sounds intros and endings, these sounds have been mixed by John, but with practice you could make the same sounds.
The book I purchased cannot be brought in the UK, its called 100 Instrumental Songs a German Music Book.
This book contains some lovely foreign music which you would not be normally available.
John made a USB of the registrations to go with this book, I must admit I did overwrite some of the instruments as I thought the blend was not quite right. The sounds on You Tube will not be the same sounds you produce, John has a lot of experience and technique, this is what makes these sounds good. My advice would be if you have the time mix the sounds you like yourself.
I am new to the Tyros 5 and was having trouble getting a nice string sound, I ended up with using legacy strings with Tyros 5 and Genos
strings, work that one out. But it takes time, John does that for you.
Hope this helps
Regards
Steve
