Yes, nice, it was about Pachelbel’s famous chord progression. For example it occurs in „Coolio – C U When U Get There“. Everywhere on the internet is mentioned, that it isn’t respectively has never been protected. I used this for two loops by different ways (chords and arpeggios) and played it with my own instruments. The effects I have also chosen by myself. No problem from my point of view. Then I became blocked because of “Breach of Copyright”. I couldn’t understand it and was a little bit annoyed. But seemingly generally no strange content is required on this portal, no matter, when it was created.
