No, squeak... Epic Fail!
The Roland Chord Sequencer was a LIVE tool. It wasn't preset changes, it actually recorded what you played, while you were playing it, then played it back seamlessly while you did something else...
Play the head for the tune while in record, then hit Play (no interruption or stopping) and the CS took over the chord input duties for the arranger section while you solo your brains out, play another instrument, have a beer, whatever! Start playing the bridge when it comes in (you can make the CS stop without the style stopping), then hit Play again, vamp out, whatever you feel like.
Play the song differently every night, the CS is different every night.
I see little point in preset changes, or pre-done chord sequences. Might as well use an SMF with Markers... The Roland Chord Sequencer had exactly the same philosophy as the arranger does... no rules, no limits, do what YOU want to do, when YOU want to do it.
That it didn't become as standard a feature on ALL arrangers as SMF playback or mp3 playback is one of life's great mysteries...
Let's face it, once you have played a verse and chorus ONCE, repeating the changes in realtime is a complete WASTE of your LH, if you have a CS to play them for you. 50% of your capability is being wasted on mere repetition. I don't know about you, but I got better and more interesting things to do with my LH that simply input the chords AGAIN and AGAIN for the stupid chord recognition section of your arranger.
Somebody, ANYBODY... Bring back the Chord Sequencer the way Roland got it RIGHT.
