Hi,

the Korg arrangers (the one I know, don't know for other brands) are very flexible and any style element has the same parameter set (this back to earlier Pa80 times).

This means that if I can put a chord progression in the intro 1 (as we know being possible) this can be possible in any other place (say any Intro, any Fill/Break, any Var, any Ending).
The only difference available is between Vars (having max 6 chord variations) and the other style elements (having max 2 cv).
For the given case the NTT Table to be used is "No Transpose", that's it.

I used chord progression in variations several times (especially for song styles) and this looks very similar to the "Riff" feature available in Ketron (even if I don't how pratically this it is done in this arranger).

Actually with the "Chord Sequencer", something I was really looking at to free-up my left hand for improvvisations, I think will need less this, even if probably sometimes could be more practical (it depends).

I'm not usually discussing that much here but, as said by others, this thread looks very interesting so keep going on.

Hope this help. Cheers.
