I really don't want to debate the issue any further. I posted initially to document what I perceive as an inconvenience, or potential shortcoming for anyone else out there who happens to think and play as I do. Based on posts I've read on the Korg Forums and PSR Tutorial, I KNOW there are others who were frustrated and disappointed to learn that a new board didn't incorporate the chord fingering they were used to. If any of them are also here on SynthZone and stumble across this thread, I don't blame them for staying on the sidelines and out of this fracas!
Re: software development. I've repeatedly mentioned that "Klaus" reached out to me, and we worked together to add Roland-style chord recognition to his software arranger Nimbu. I didn't pay him, and he didn't compensate me for the time I invested. Perhaps the same thing will happen with Giglad. And why would I pay? Based on my reading of the documentation, I just wouldn't buy the product as it currently stands. As I pointed out in my reply to Bill, additional chord recognition modes are a win-win for users AND the developer because they expand the potential sales base.
You've repeatedly characterized my observations and exhortations as a "problem." I've tried to demonstrate to you and other trained musicians here that they are also an opportunity.
Have you ever studied the history of the QWERTY keyboard layout? It's nearly universal, but it's also widely acknowledged to be sub-optimal. Common English vowels are hard to reach, etc. When the typewriter was first invented, QWERTY was seemingly a physical necessity to avoid 'key clash.' By the mid-20th Century, new mechanical designs eliminated any possibility of key clash. QWERTY is still the dominant layout (and collective typing ease likely suffers as a result!) However... there is a tiny percentage of users who have explored improved keyboard layouts like Dvorak and Colemak. I encourage you to Google these if you're not familiar with them. Windows supports this minority of users through customizable settings, remapping keyboard input to conform to these layouts. I think this is a reasonable analogy to my observations about Giglad, and simplified chord systems in general.
As a side note, Roland-style partial chord fingering isn't "defunct." I briefly tested the new Ketron Event and it seemed to demonstrate 100% conformance. Every Casio model made since 2012 or so has about 95% conformance, enough to play most songs without re-learning. Casios are often "first keyboards" for nascent musicians and the musically curious. That's a lot of users, but probably not here on the 'zone. Roland's E-A7 is still available new at retail. And the FP-E50 and latest Go:Keys models use Roland's venerable Chord Intelligence as originally devised in 1991.
We all come to our beloved arrangers from different viewpoints, with different hopes and expectations. As a home hobbyist, part of the appeal for me is that these machines are musical automatic weapons, a novelty and "force multiplier" for someone of lower skill. The first true Arranger was the Hammond S6 chord organ, a purpose-built "easy play" instrument that wasn't even a good gateway to learning a "real" home organ. Laurens Hammond himself wasn't a musician, he was an engineer! So please don't hate on me for hoping to sustain this facet of arranger tradition. Whether or not you agree, I'm grateful that you let me hang out on the 'Zone, and that it provides an enduring forum for healthy discourse.
