I just installed the VST Hypersonic 2 on my computer who is GM compliant.

I loaded on the vArranger software, the Tyros 3 Bebop style, who sounds amazing to my ears

I added the chords with the SONG CHORDS feature

HERE is the MP3 recording of the result, direct out from the VST host, with NO tweaking at all.

It's amazing that we can create a quality backing track in less than 5 minutes !!
