Casio CZ/ VZ/ FZ - Pro Series

Sorry if this is a little off topic, but i figured this would be a
better place than any considereing the appreciation for cheaper but
quality sounds. Can anyone recommend a  casio/casiotone/anybrand that
has strong fingered chord sounds, that will play minor/seventh chords?
without rhythm accompaniment. Just solo, long tone chords. Like older
organs.

Thanks,
