| Faustino Stringfellow 29.11.2012 | Because I'm only working from a picture, i would suggest that you find a multimeter and trace the circuits. From what i can seesolder points.jpg this is where you need to connect. Follow the same, check first, solder later .....be VERY careful that don't join solder pads together, I can't see whats on the other side, but those top connections look as if they may be connected to a chip which will be damaged if it gets too much heat. |
| Bobby Verner 28.11.2012 | I've soldered before but i'll have some practise anyway in order to do it perfect. JSM thank you very much for the advises. should I solder the 2 wires from my arcade buttons on the 2 solderpoints? How should i connect the 2 top carbon pads? (like it says in the photo) Thanks, Alex PS: boarderbas you could be more helpful, not everyone understands cirtcuits.

| Bobby Verner 26.11.2012 | i'm bringing this up again cause i really want to know exactly how do i solder the arcade button on the 4 black connectors? thank in advance, alex |
| Lorrine Eckstein 22.03.2010 | Nice!! Thanks for all the comments/Advice you guys are stars! :P |
| Annabel Trancosa 22.03.2010 | 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 |

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. |
| Annabel Trancosa 22.03.2010 | 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. |
| Lorrine Eckstein 10.02.2010 | 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 |
| Al Henger 07.02.2010 | believe of it like a korg nanokey. |
| Iola Obradovich 07.02.2010 | but they will loose any velocity sensitivity if they have it. |
| Love Kocurek 07.02.2010 | yes... |
