"I think the Scaler surpasses "chord builder" in many (MANY!) ways, except of course, for entering chords directly to bars." AND "for BIAB I installed 32Bit VST, which I can not get to work. VST simply does not start/load."

I find that to be kind of a 'deal breaker' since you can accomplish the task in the BIAB "chord builder" quicker than you can say VST three times in a row. In your particular case it doesn't matter if it has better features in one way or a thousand if it doesn't work.
