Yamaha Arranger anomaly

Playing ACMP on Yamaha E models and S models.

Please try this and report back . .

Play a C+ chord (left hand)
C1 E1 and G#1
That is a Caug (C+) chord.

Now play inversion . .
C2 E2 and G#1
What do you get?

I get Ab+

I prefer to play inversion chords because they use less petrol in finger displacement.
Why does this inversion not work properly?
What other inversion chords are wrong?

Because that's what happens when you allow a machine to play a chord for you

Clearly a bug.

Contact support and grow old and die waiting for a fix

Btw. The algorithm probably only works with root note in first position.

All other chord inversions which I use work fine with root note at 2, 3 or 4.

I thought about that and experimented.

I think the "bug" answer sums it up.
Thanks mate!

Bienvenue mon ami.

I was wondering if Casios, Korgs, Roland etc.. have the same bug.

Hey Ray,

The machine is not faulty. Ab aug and C aug contain the same notes. The machine is just making a different nomenclature choice because by playing the inversion you are making Ab the root in its “mind”.

Normally in a case like this the label of the chord would be determined by the key signature of the song. Of course your machine won’t know that.

Hope that helps?

Yeah mate! Certainly explains it. Thanks
However, the inversion Ab+ does sound slightly different than the standard triad C+
The difference is very minute and hardly even noticeable. I only noticed the difference because I experimented.

The C+ chord is very common in many tunes following after a C chord. The sound transformation is a joy to hear.

C chord inversion followed by C+ inversion is so easy to play.

Yep it will sound slightly different because it's inverted. But it's the same notes. You'll find it doesn't sound "wrong", just different.

Every major chord (example, C Major or C,E,G) when moved to the first inversion (E,G,C) is an Augmented chord of its root, in this case E Min Augmented. CMaj7 when inverted is a EMin augmented. Pick any chord any follow the pattern and you always get the min equivalent. There are other consistent patterns of major/minor equivalents. They sound different because the bottom note drives the sound your ear hears and because general hearing loss of old age effects the highs more than the lows. This makes the sound difference even more prevalent.
