Picked up an old midibox lc off ebay cheap, it powers on fine and seems ok. Its not a unit that I am familiar with but its something for me to tinker with in these winter evenings. Couple of questions, 1: the core's are old home made cores , I still have a couple of smash tv's core 8 pcbs here, can i replace the others with those, I am assuming i can 2: the MF was replaced with the MF_NG so I am going to buy one of those to replace the old MF pcb I see this can be linked to the pc directly rather than the cores. Anything else i should know on this replacement? Plan is the put one of my old GM5 midi interface boards in there and have the MF_NG and the cores midi route into that then out via usb as i have done on previous projects. This one boots up with the message logic control emulation, is this the same protocol for use in Mackie HUI mode or is it a different set of settings i cant for the life of me remember if the logic protocol is the mackie protocol or if its a different settings hex file that needs to be uploaded for it to be a mackie HUI configuration. If anyone still has an old LC kicking around or has modified theirs to a better setup I would love to chat about it and pick some tips up while i tinker with this. The wiring needs re-newing and the casework is going to be media blasted and powdercoated in the meantime. Thanks SSP

search and you shall find.. yep its been done before..

Just popped in as I am currently building a new self contained synth, still using this Bad Boy after all these years. Never let me down once!!

only just saw this, been a while since i was last here. weird no one referred you to my thread. here you go.

Here you go i built one a while ago it does everything that a daw needs.

Hey sauren, its been a while since i had a chance to pop in here. Really nice to see how far you have come with the project. I cant wait to see it all cased up and finished. Well done, glad to see you stuck at it!!!

Been away a while, still busy making blue smoke and still writing music and producing. here is the last revision of beltram, now mastered up and re-eq'ed. Enjoy!! http://soundcloud.com/pherik/beltram-new-mix

I need some gm5 chips for my remaining boards so if there are chips for sale i will take them ;)

Hello stranger! wow long time, you still over at banging tunes then? i haven't been on there in a long time. Still keeping up with mr Parkes though on facebook I may know someone who could be interested in them. Need an idea of pricing though. let me know what you are thinking of and i can pass the info on, also if needed can you email me over some hi res pics? thanks ssp

a hair dryer won't nearly be hot enough... you need a heat gun or hot air smt station to heat it up enough.

ok the nut is for an encoder, however you can only use it if the hole in the rear mount plate is the same diameter with tolerance as the diameter of the threaded shaft on your encoder, mine was the wrong size it was all they had at the time so i mounted it on a rear mount board. if your using an alps or bourne encoder the centre hole needs to be 9mm, so you may need a 9mm drill bit and make the hole larger so yuu can use the nut the other side.

just wondering, did you ground the pins on J5 if you have no analogue inputs or did you change the asm file? this is from on of my earlier posts: When i need to test just one or two pots i just connect directly to J5, and i then go into the asm file and change these lines and then recompile, it saves me having to ground things. So obviously i connect the pots as follows, Pot1: Vs/Vd/A0 Pot2: Vs/Vd/A1 Pot3: Vs/Vd/A2 (connecting to correct pins on pot!!) So i open for example setup_midibox64e.asm in my text editor #define DEFAULT_NUMBER_AIN 64 (the amount of pots/faders connected, more than 8 needs an ain board and MUX to be enabled) #define DEFAULT_ENABLE_AIN_MUX 1 (needed for when you use the ain boards and more than 8 pots) I then change them to this as i only need say for example 3 pots and no mux as im connected directly and not through an AIN board #define DEFAULT_NUMBER_AIN 3 #define DEFAULT_ENABLE_AIN_MUX 0 by doing this, the software only looks for the first 3 inputs on J5, the other 5 are not looked at and therefore i do not need to ground them. So if you do not have any pots or faders then change it to this #define DEFAULT_NUMBER_AIN 0 #define DEFAULT_ENABLE_AIN_MUX 0 if the J5 pins are not grounded then they cause spurious midi data that is constantly running. As explained changing the code saves soldering! see if that helps first Its surprising how easy it is to forget to ground the pins on j5 or edit the asm.

heres the midiox data when the fader is pushed up slowly, it has to be a 10bit resolution for the daw to accept it as its default without mapping it. fader decimal.txt fader hex output.txt
