Midi Keyboard Mod, Can it be done?

[CuttaBoi]

Hey, does anybody know if a midi keyboards Keys can be taken off and have arcade buttons soldered in?

Thanks in advance!

yes...

but they will loose any velocity sensitivity if they have it.

Thanks for you're responses

Does anyone know of any tutorials? Or how difficult it would be to do (possibly to an Oxygen 8) ?

Looking to use it for Cue Point Juggling & controlling 2 effects units in Traktor...

Thanks in advance

I'd say it's not the hardest thing to solder, but If you haven't done any soldering before I wouldn't suggest it to be your first project, but with a little help it can be done.

I dont have a tutorial im affraid but it should be trivial just track the connection of the keys back to a solderable point on the circuit board (their is likely a shared negative terminal then one or two positive for each key) and replace the key with the button. It probably dosent even matter which way you add the button, but be sure to practice soldering on a few scrap components first if your new to soldering (maybe buy a begginers kit) as once you have damaged the circuit board their is no going back.

I took a few pictures from my oxygen 8 v.1 It's not probably same as the v.2 and v.3 but should be similar enough for showing where the buttons should be soldered.


this first picture shows the pads under the keys, and under the rubber pads where the actual connectors are. there are total of 4 of black connectors and when two of them are connected, it will transmit a midi note. The reason why there's two connectors probably has something to do with velocity, since there seems not to be any more connectors for velocity. I have bigger keyboard with real hammer keys and it has a similar system but it has two connectors more for velocity under the keys.


If you don't want to mess with keyboard section, this could be good place to add the keys.


this could be also another good spot to add the keys, but If I have understood right the midi note is changed by the value of the resistor, so you have to either buy a resistor with same value as the original key or use the one from the board.

I hope this helps a bit

Nice!! Thanks for all the comments/Advice you guys are stars! :P
