Build Log} DIY Midi Mixer/Controller {x8-Arcade
Build Log} DIY Midi Mixer/Controller {x8-Arcade Posted on: 13.04.2011 by Leonardo Papajohn I've been contemplating building a controller for a while now, and with watching and reading on other peoples build log's it encouraged me to move forward with my ideas. So the way my idea started is because I have an extra fully functional Lpd8 board, and I was believeing if it would possible to do an arcade mod with it. So I posted a thread on asking if anyone knew if it could be done, AND it very much so can be. So with that great news it got me believeing that I could do this and some how incorporate my M-Audio X-Session Pro that is also collecting dust. So I came up with the idea plan above. I wouldn't be adding anything really other then the arcade buttons and casing, It would just be me more so rearranging things to my liking. Heres a look at what I'm using: (not this exact hub, but one similar) :eek: Now the tricky part for me is how to go about removing the knob pots and faders rearranging and then adding wire to connect em back to the board(s). So I'm kinda relying on you guys to dump some more knowledge on me, on what is the best way to go about doing this. Thanks in advance. | |

| Shana Minsk 30.04.2011 | Very useful video. Good to know I don't need to desolder the old pots in order for the new pots to work. |

| Arcelia Siebeneck 29.04.2011 | here's a video of the LPD8 circuit board... pretty easy to solder replacement faders/pots on to it: http://www.youtube.com/watch?v=8a7NU98fSMI |
| Shay Wyche 13.04.2011 | Keep a look out for old faulty mixers on Ebay and the like. Sometimes you can pick them up for next to nothing and strip out all the internal wiring etc. |
| Leonardo Papajohn 13.04.2011 | Also, does anyone have any recommendations for enclosures? I've seen these on the community s, but they seem to small for what im doing? (Maybe I'm reading the measurements wrong?) |
| Leonardo Papajohn 13.04.2011 | Kinda something like that, Im gonna have both the xsession and lpd8 boards cased in there using them as they normally would (just rearranged some how lol) hooked up to a usb hub. Idk, if you can understand how for what im explaining lol but it makes sense in my head lol |
| Matha Obray 13.04.2011 | Nice! are u going to use the x-session as like a base and build on top of it? |
