Why the interest dies off?
Too expensive ?

people go for cheaper 21-61 keys midi controller i guess limitless library of sounds when connected to DAW

people wanna sell their Rm25,000 organ for RM500 pun takde pembeli. Nobody wants organ anymore since 20 years ago.

Why the loss of interest leh?

I guess a few:

1. You learn to play piano, you can play organ or any keyboard instruments, you play organ, you are not trained to play piano.

2. Digital piano taking over Organ roles. I have a Digital piano myself. Computers + software + MIDI keyboards can also take over, more flexible to upgrade, cheaper price. Almost everyone already has a laptop/PC at home. Most home got > 1 PC/laptop.

3. You got see Organ in Ochestra Symphonies or not?

Considering the electone requires 4 actively moving limbs, I would argue that it’s not at all comparable to playing
piano, and demands a greater level of hand/foot independence.

DAWs are not the issue. Orchestral roles are not the issue either.

The issue is that there is just not enough appreciation for music that uses organs, and not enough good teachers/players to help inspire more appreciation.

From my observation, this isn't so.

The scores made for Piano is so different that when you get a pianist to go on an Organ, they can play it as a piano but they can't handle it utilize it as good as one who is proficient in organ.

Basically they have things in common (black and white keys) but how both are played are quite different.

Dont agree. Its easy to play organ if you know how to play piano. Seen many players do it. Learning to play piano from an organ exclusive background is different story as organist needs to retrain their fingers strength and control to handle the piano keys weight.

Pianist just have to kept in mind is organ is a wind instrument and make adjustment accordingly (need to take a bit of time of course).

You do realize we're talking about this organ, right?

Yes. You do realize organ voice whether digital or analog is still a wind instrument right?

I have nothing to reply if you insist an Electone Organ is a wind instrument.

I mean, sure, if your understanding of playing organ is simply pressing keys. Don't forget there are also pedals and switches, and the style of playing is completely different (even solely within the context of pop music).

I don't think any one transition is necessarily harder than the other; each presents its own set of challenges, but organs require a higher level of multitasking so there's that...

I would also argue that playing unweighted keys takes a lot more strength/velocity control because you don't have the keys' resistance to help you gauge any of that.
