Diki, your ideas sound great..Maybe Roland is already working on it[maybe they are tired of your complaining about the chord sequencer]..
BTW: The E600 chord sequencer doesn't allow for us to use in realtime like the G1000 did..It was designed to save and recall..
The new G series is already in the making..My bet ..you will see the Sonic Cell features incorporated..
Still hope for the CS..And I also can not see why more old G1000 owners never used it..It was the best song writing tool ..
I use to write songs for a gentlemen that wrote lyrics, and chord progressions..It was an easy job for me to put a demo together for him..using the chord sequencer..
