want to convert MF to MFPRO with EXACT same midi notes Posted on: 07.07.2011 by Chin Thoroughgood I want to build 2 MFPROs (one of each of the "XX Fader" and one of the "Beat Masher" types) out of my existing midifighters. I have done some research and know that it is possible for this to be done through the analog and digital expansion ports built on every MF. I would like to know how I could create them so the midi notes are the same as the MFPROs so that the new (and any future) mappings will work without much (preferably no) modification. I am a design student with access to practically every type of tool you could dream of and have unlimited free materials. I was going to put a sweet case on these (probably a nice cherry wood case ) and some extra modifications as well. The things I want to know are: 1) What extra parts I am going to need other than obvious ones like pots, knob caps, faders, wires, buttons, and of coarse the face/back plates. I mean things that aren't seen on the new MFPROs things like multiplexers etc. (if so what kind or model number?) I know about mouser and other part stores (but links are always appreciated!) 2) How would I go about wiring such a device? As I said before I dont want to do much mapping, I would really like it if someone could post a diagram (MS paint is great, I am not looking for quality art just what connection goes where ). Has anyone popped open there MFPRO to check it out and would be willing to help? I also noticed that the new MF's and MFPROs have there expansion ports in two rows of 5, I have an older model that is one row of 10, which looks like this: (from top to bottom) GND D4 D3 D2 D1 A4 A3 A2 A1 5V I am wondering how the new ones are arranged, if anyone has a newer MF can you please let me know how they are laid out so all of the wiring is exact. 3) Do I need to run any sort of HID to MIDI programs or is all of that taken care of through the firmware of the MF PCB? 4) am I missing anything? If so PLEASE let me know! THANKS IN ADVANCE YOU GUYS ROCK!!!!! | |

| Chin Thoroughgood 08.07.2011 | Thank you very much! Now the LEDs you're reffering to getting to work, are those the existing LEDs on the MF PCB itself or the LEDs corresponding to the 4 bank selection buttons? Thanks again! I am about to order parts and start cutting acrylic . p.s. 10k ohm 60mm slide pots, 10k ohm 7 o'clock to 5 o'clock pots right? and any button style I want essentially or is there a specific type I need to get? do they need to be 10k ohm as well or does that not matter? I know the ones on the MFPRO's light up when selected (hence the multiplexer/LED controller you mentioned) I've been digging around and found this: http://www.djranking s.com/community /sho...ht=multiplexer is CD4051B the part number of the multiplexer I'd need? also do I need any specific kind of board to solder to (or at all)? (I would like to make everything as easy and hassle free as possible but definately want a full functiong MFPRO that will work "out of the box" with the new and and any future mappings. Thanks alot! |
| robert chanda 08.07.2011 | Depends if the LED feedback is important to you. If not, it's as simple as putting the thing together. If you do care, it involves a multiplexer and an LED controller with the digital lines being CLOCK, LATCH, DATA and DEVICE_SELECT. You also have to do a little reprogramming as the DATA line has to be used bidirectionally. |
| Chin Thoroughgood 08.07.2011 | So I don't need any multiplexers, or anything like that just some wire/pots/faders and the correct connections to get it to work exactly like the MFPRO? |

| robert chanda 08.07.2011 | You have the MIDI map. You have the source code. You have the schematics. Go for it. |
