On Bass Chords???
« on: October 05, 2018, 12:14:23 AM »
Hi everyone,

I have begun trying out some features of the PSR E463 and, damn it, apparently it hasn’t the On Bass chord recognition mode.

Of course the E series never had proper On Bass chord recognition, but there was a workaround in that if you played a C chord with four notes with the bass repeated at the octave, for example G C E G, you would then get a C/G chord instead of a regukar C chord in root position.

Apparently the E463 doesn’t have this feature so now I am wondering whether the older models had it or not?

I think that I was able to play C/G chords on my old E433, but now I am starting to have doubts... Could anybody with a PSR E433 check this, please?

If the older E 4xx models could understand chords spelled G C E G but the E463 can’t, now this is a serious flaw...  :o

I'm not aware of anything like that on the PSR-E models.

Indeed probably not. I think I am confusing with the DGX series, for which you can use this neat trick. Too bad for « Whiter Shade of Pale »...

If I am getting it, you are talking about Chords getting detected and displayed on screen, without the styles being played in background.

Hello Anupam,

Not quite. I am speaking about the way a keyboard tracks the chord played with your left hand to generate the auto-accompaniment.

On higher-end keyboards such as the Genos, Tyros or PSR S, you can choose a chord detection mode where the keyboard recognises in which inversion you are playing a chord. If you select this mode, the keyboard will then be able to make a difference between a C chord spelled C E G, a C/E chord spelled E G C and a C/G chord spelled G C E.

Lower-end keyboards can’t make a difference between these chords and will always play them C E G, thus with C on the bass, even when you play them in various inversions.

On some keyboards, there was a way to “cheat” to play these chords in the correct inversion: if you played the chord with a note repeated at the octave, this repeated note would then be used as the bass note of the chord.
For instance, if you wanted to have a C/G chord, you could play your chord spelled G C E G, thus with the G repeated at the octave, and the keyboard would correctly use G as the bass note instead of the root note C. This was very handy to play songs such as a Whiter Shade of Pale by Procol Harum, where the chords in the introduction have other notes than the root note as the bass note.

Unfortunately the PSR E463 doesn’t have this “cheat mode” to play inverted chords. My DGX650 can do that, and I thought that the PSR E433 could do it as well, but I am probably mistaken... :o

Hi Roy,

Thanks for this clarification. This means that the first Yamaha arranger keyboard which detects on-bass chord is the PSR S670. This is a thing to be aware of.

I've not tried a 463 but, FWIW my E443 and even my old E403 could play a limited number of inverted chords with just two keys, just as AI Fingered Mode does on the larger keyboards.

To get C/G, you simply play a C over a G - or G and C from left to right if you prefer thinking of it that way. Similarly, C/E is a C over an E - or E C from left to right. No need to play four notes. I get my students using this early on - before they tackle Grade 1.

It can't of course play things like G/F as that will trigger 'single finger' chords and give you G7, and neither can it do minors or any more complex chords.

I'd be surprised if the 463 didn't do the same, but like I said, I haven't tried it.
It's not what you play, it's not how you play. It's the fact that you're playing that counts.

Hi Andy,

Thank you very much for what looks like a very nice workaround. I will try it on the PSR E463.

Best Regards,

I'm not sure-- since I don't actually use styles very much-- but I should think that this behavior might also depend on the style itself, since the various settings in the CASM chunk, not to mention the notes which are defined for the various style parts in the MTrk chunk, are what control the specifics of each style.

But to repeat what I said before, I'm not aware of any particular "trick" or playing method for triggering an On Bass Chord, and if Andy's method does work then I'd hope it works regardless of whether you're fingering an abbreviated chord or full chord.

Unfortunately, the PSR-E Owner's Manuals are a bit skimpy when it comes to certain technical instructions and details-- e.g., the Owner's Manual for the PSR-E403/YPT-400 has a page which lists all chord types that can be detected, with both the required and optional notes for each type of chord; but that page was dropped from the Owner's Manuals of later PSR-E4xx models.

Sorry I'm too late, just got to login to the forum.
Well now I got it. That four note inversion of Chord makes no difference at all, in styles played in auto accomp.

that fourth note DOES make a difference, much like making chords on the lower manual of an organ, but when a rhythm IS running, that fourth note makes absolutely NO difference in the sound of the chord.  That is to say, when a rhythm is running, adding the fourth note does NOT force an on-bass chord on the PSR-E433, and I assume that this probably applies to the entire PSR-E4XX line, and most likely to the entire PSR-E series.

Yes Roy, that does not make a difference, it just triggers the regular Chord on styles, but the bass Accomp (without style) does pick up some bass lining with it (I would check it myself). Now that I am not much familiar with the S-series keyboards, I don't know how its styles work, actually I have learnt playing these keyboards like solo instrument synth, and not arranger. Playing melody with styles (auto accomp) is something I have not mastered myself with yet. :)
