The Korg CS, is okay, as in it works, but it IS "clunky" to set up "on the fly" as it were, which is essentially how one would use it . When actually playing a style live.

It requires a certain dexterity of button pushing, ie two buttons need to pushed simultaneously..if you miss the timing slightly, eg push one button a few milliseconds before the other, it does not start recording WHEN you need it to. Needing a second go.

The same can be said for the stopping of the recording and then having it switch to the "playback mode", if you do not press the same two buttons at precisely the same time the recording phase does not stop requiring a further "double" press.

Trust me when I say that this is exacerbated even further when you are in the middle of a 180bpm bebop tune, trying to not only play the song, sing the song, worry about chord changes and THEN try to set up what I consider to be a very "fiddly " process...maybe it can be achieved by solid practice of accessing the mode...

However if one manages to negotiate the starting and stopping of the recording phase, the actual playing back of the sequence, and subsequent stopping again needs the push of only one button...which is really how the recording phase should be too..

No, imho, in practical terms, the chord sequencer is really only "useable" BEFORE you start the style....ie load up your style and BEFORE starting to play set the CS to record then start your style...of course you are then limited to ONLY what chord progression you start the song with...in a lot of cases this works out to be the main head anyway, so no real problems.

I just think Korg could have implemented this a whole lot better, and it does strike me as a "late addition" rather than a full pre-planned tool.

The Roland CS, certainly was a lot easier to implement, PLUS it had the huge advantage of being able to save the CS to file, for a later performance of that same style/song.
