I answer to myself: Scaler is good at rock!
I started sending the output to my amped guitar, then I found a few chords: 1 set for the verse, and a second set for the variation (sorry for the improper term I am a rabbit composer 
)
then I set by ear the lenght and x time for each chord in the editor, then added the proper expression, phrase, arpeggio or strumming
at the end I recorded the MIDI of 2 sets and moved them to Ableton guitar line
then added the drums and the bass, and here is the result with minimal effort and no knowledge of musical thory
