Therefore, the MZ-X series has in the auto-accompaniment section the same rhythm editing features and no other additional extra settings compared to the CT-X series. But the MZ-X series has a more intuitive and more practical graphic interface thanks to the touchscreen display.
The truth is that would have been very useful on the CT-X series a GUI like in the MZ-X series, with a touchscreen display and more real-time tone and rhythm controllers (buttons, knobs, sliders, etc.) on the front panel. But at its price we cannot have so many claims from the CT-X series.
I have other problems to solve now in my personal life, but in the future I will try to compensate all the missing live controllers in my CT-X5000 with a iPad MIDI App, something like the "MIDI Designer Pro2" for example.
Regarding to the Korg CVs, my question was if I can configure the MZ-X auto-accompaniment rhythm such that, in Variation 1 for example, the Bass line to have a certain accompaniment pattern for CMaj chord, another accompaniment pattern for C7 chord, and a completely different accompaniment pattern for Cdim chord.
Korg arrangers allows 6 CVs (Chord Variations) for each Style/Rhythm Variation, and each CV is configurable by the user. Which can set as for a certain chord, a certain CV, which play a certain accompaniment pattern. For another chord can set another CV which play another accompaniment pattern. And so on, up to 6 CVs, which allow the user to play 6 different user preconfigured accompaniment patterns through 6 different chords in the same Style/Rhythm Variation.
