LED on keyboard

Backyard electronics

Hi. I just joined keyboard forums. Hope you are all well.
I am a bit of a backyard electronics buff with absolutely no experience, knowledge or training.
I am in the process of modifying a music keyboard that has Red LED’s only when you strike the keys.
I have successfully removed most of the Red lights and added Green, Orange and Yellow as they are close in voltages, resistor and mcd values using a battery powered soldering iron using low power 30 watts and a 3 second window when doing do avoid damaging components.
Blue and White LED’s have different specs but am googling for ideas on modifying these with components if possible.
Not fully completed as I just started thinking about it a day before I became a member.
Some pics added, I could not find a link to attach a short video of it in action.

Any comments negative and positive are welcome.

Updated photos have to order more LED’s from aliexpress cheap as chips.

And 88 of those things are going to increase the power supply load by at least a full watt or three.

I’m an only replacing 25 of the original Red LED’s and leaving the rest in. It will increase the power wattage a little.

Took 1 Red LED from the keyboard to the electronics shop and the tech support advised me the original LED was very bright.
So no extra power needed unless you go over the specs of the original LED, problem cost to buy 25 LED’s in the shop about US$40. Aliexpress much cheaper. Updated photo can get the colour and size pretty close by adjusting legs of the LED when soldering noting the white and blue need to be pushed down further when re heating the solder and cutting off the excess legs.

Photo 2 shows the C key as a RED light.
The next RED light is on B key.
So the next octave will be different than the preceding octave.
Wouldn't that be a distraction when playing tunes? Shouldn't each octave be uniform (same colours)?
Why am I even discussing this?
I am betting you play hip hop or house music . . Yes?
That kind of music is electronically programed, dull and boring so adding lighting effects may enhance your senses.
Good luck.

It ain't star trek enough.

The kewl nerds are all playing laser harps...

If that is real it’s amazing technology I’ll look it up.
Update:
Cut a LED of a strip and soldered it to the board, colour is uniform no circular dot lighting up.

Actually, a keyboard player gets his bearings by black keys and white keys.

For that matter, why not get multicolored LEDs and strobe them in patterns?

That's what manufacturers of modern synths and groove boxes are doing.

The first thing I do with one is turn off the nauseating light show.

And the laser harp has been real over 2 decades now.

Look for an old thread called "weird and wonderful" and enjoy the ride. :D

I am not a keyboard player, I got a 2nd hand one cheap to muck around with.

I have looked at some threads with midi to trigger lights with keys. I agree to many lights.

I can turn key lights off at a press of a switch.

Most musical instrument manufacturers use similar LED technology but my advice do not attempt this project with vintage or expensive instruments.

I might continue the project some time down the track of all lights cut from a Blue LED light strip and have a brightness control function

Laser harp amazing technology.
Thanks for the info.
