What is relation of CHORD LOOPER to vRIFF and SONG CHORDS features?

[nonchai]

Hi

What is the relation of the CHORD LOOPER feature to vRIFF and SONG CHORDS?

Is it possible to

1 ) edit chord looper recordings - including quantising them

2 ) can the chord looper recordings be saved and imported into the SONG CHORDS feature and edited some more there - or are these two features entirely separate?  ( and if so - why? )

3 ) can a CHORD LOOPER recording be converted or imported into a vRIFF?
