Yamaha Education Suite (Y.E.S., including Chord Dictionary) useless?

[tf88]

Hi all,

I'm still at the beginning of learning to play (as an adult learner), and I'm not yet fixated on any genre of music. My plan is to start out with the fundamentals, meaning primarily basic exercises and music theory, not necessarily playing specific songs. But I thought it might be beneficial (or even fun?) to also make use of Yamaha's "Education Suite" (Y.E.S.) with its 3-step learning program. I also thought the "chord dictionary" could be really useful. Both used to be included in all PSR-E keyboards until recently.

But I came across a second-hand PSR-EW410 (I wanted a 76-key keyboard) that I bought for its very low price. This is one of the newer 4xx top-of-the-line PSR-E models from which Yamaha removed both the Y.E.S. and the Chord Dictionary (as well as "Keys to Success"), while they were retained in the lower models.

Now there is a PSR-EW400 (the predecessor of the EW410 which still has the two features) on offer fairly close to my place for almost the same price (only a bit more), and I'm wondering if it's worth buying this one as well, just for Y.E.S. and chord dictionary. All other differences between the two models are irrelevant for my decision. That would mean yet another trip to a seller, and spending more money than I actually wanted, at least until I can sell the EW410 again (possibly at a loss). I wonder if the learning features are worth the hassle.

I have seen some online reviewers/influencers bash those traditional Yamaha onboard learning features as "outdated", and touting the virtues of online courses, but I certainly don't want take one of those. I'd rather get real in-person lessons with a real teacher. Yamaha themselves obviously found those features dispensable on their higher-end PSR-E's, and maybe only kept them on the 3xx/2xx models just for marketing purposes.

So, do you think the onboard learning features are of any value or not?

(And if you want to know, yes, I actually like some of the old built-in songs, or at least would find them okay for learning purposes.)

Oh, and another aspect: The only external add-on solution I could think of would be some MIDI-connected app (no subscription, please) that in effect does about the same, preferably with songs you can feed into it yourself.

TIA
