Sorry Bill, it's not my intention to stir up hard feelings. I think the appearance of disagreement is because some of you are looking at this from the perspective of musicianship rather than engineering or ergonomics.

During the '90s and early 2000s Korg, Roland, and Casio DID add Yamaha's "nearest black key to the left" system. In some cases it was even added to existing arrangers through an OS update. Not because it's better (it's not), but possibly because those brands wanted to attract Yamaha/Technics players who had already learned to play songs using that system, and novices who perceive it as easier. Above and in other posts I've stated that ALL manufacturers should provide as many fingering choices as possible, to accommodate the broadest cross-section of potential users. Even the "standard chord system," i.e., fully-fingered chords, has a few wrinkles. For example: should E-G-A-C be recognized as Am7 or C6? (Remember, arrangers also sound the bass, so there's a big difference in the sound.) Casio lets you choose!

Perhaps I'm shortsighted and stubborn (and I don't mind you pointing that out!) But it isn't my goal to be able to sit down and play any keyboard. Only to play many common chords in the easiest, most comfortable way possible, with a minimum of hand movement. Almost every brand including Giglad has system(s) that allow players to trigger chords by pressing a SUBSET of notes that make up the full chord. How can pressing three or four keys be easier than pressing just one or two from that same set of keys? When you think about playing successive chords--progressions--soon the need to reach those extra notes will to force you to move your whole hand. I've observed that pressing more keys and/or moving my hand increases the likelihood of playing a wrong or late note. And any of the "easy chord" systems are a boon to amputees or persons with limited finger articulation.

I'm not a pro, so I'll never be asked to sit down and play a gig on someone else's instrument at short notice. This gives me full freedom to choose a system that I believe reduces playing mistakes. Also I'm not complaining. I'm trying to prevent disappointment for anyone who relies on the aforementioned "intelligent" systems to play slash chords. Giglad's documentation implies that "on bass" mode requires at least three keys to acknowledge a chord, so they won't be able to play those songs in Giglad with familiar fingering. As I stated in my first post, the developer could have made Bass Inversion an independent setting as it is on better arrangers from Roland, Ketron, and Korg.

Without downloading a demo and testing it, my concern is mostly about slash chords. It's a shame, because otherwise Giglad looks like a pretty nice package! Peace.
