I have a Roland electric piano which is about 10 years old or so, there are around 8/9 demo tracks on it which are prerecorded, and there is one track which I can't identify.
I've lost the manual for the piano, but I've recorded the track with a mic. You can download it here. www.amara-emerson.com / personal / pianotrack5.mp3 (remove spaces in link)
Thanks
It's by Bach – Jesu, Joy of Mans Desiring.
You can listed to it here….
