that did the trick, thanks alot! looks like the application loaded onto it before the update was a debug app rather than the correct one, which is what got me a little confused...

it was preburnt, however i couldn't add/change the configuration using mk_syx because it didnt do anything/affect the midibox in any way (and for some reason it was only transmitting over midi channel 2) thanks, i will try uploading main.hex and then the mk_syx config and report back

i thought the application is made via mk_syx? or do i have to take one of the complete applications from the downloads page, then use mk_syx? thanks in advance ash

I sent the 1.9f update to my midibox, it went fine and rebooted saying 1.9f etc. Then where it used to say Waiting for Ain/Din event... it now says "Bootloader is up-to-date", and doesnt send midi when i move the faders. I have tried using mk_syx and vmidibox64.exe to send configurations to it but it doesnt seem to be doing anything... am i missing something?

i can't get it working, after redisconnecting the lcd and attempting to solder a AIN module in, i get no random midi events like i should, and attatching a fader to the ain module and moving it results in nothing (i do get the 0 00 00 7E 40 00 01 F7 message on boot but nothing else), i'm thinking i hsould just start again and order a new core kit from smashtv or something unless you guys have any other suggestions?

adding the lcd makes the voltage drop from 4.99v to 3.4v across IC2:5 IC2:8, increasing the psu voltage to max (which outputs about 18.2v) which results in the regulator and back of the lcd becoming extremely hot, the voltage increases back to 4.7v across IC2:5 IC2:8, but results in the pic resetting over and over...

It could be, i will try adding the LCD again when I get home tonight and see if it works, if not i'll measure the voltage etc. and try turning the psu up again. I'm getting a little worried about having to resolder that part of the board though, as it is starting to become damaged due to the amount of time the soldering iron has spent near it. I'll post again once i've attatched the LCD with the results.

the regulator does not get hot anymore, and after adding solder to some joints i got 4.7 and after changing the psu voltage to '6v' (it sends out 9.6v at this, it sent out 7.5v before when set to an even lower voltage, i think the potentiometer on it must be misaligned) i now get 4.99v across vs/vd, on power i get 8 sysex bytes: F0 00 00 7E 40 00 01 F7 ...which is a good startup unless i'm mistaken, so now should i try reconnecting the lcd?

well i changed a capacitor (c5 2200uF) for a new one and removed the lcd, now there is slightly under 5v (4.6v) where there should be 5, and when powered the module sends out several hundred 1 or 2 byte sysex messages (they seem to all be 00 0F or 00 0F 00), with the occasional clock, stop and active sense message over midi according to midi monitor...

...can you think of any other components that could need replacing? or would you recommend i order a new one from smashtv and start again?

yeah it was as the pictures are, and i have just tried switching it round to the opposite of the pictures, with exactly the same results, (1.6v where there's meant to be 5v...)

the voltage on the psu is adjustable, and is set to about 7.5v, i actually replaced the 7805 with another earlier with no change in behaviour... does the polarity of the 7805 matter?

so are there no components that i could replace to solve it,or should i just start again and build another one? also after buying a new multimeter rather tahn using the one i was (which is quite probably older than me), it seems that the voltage is actually around about 1.7 where it should be 5v...

a 'universal ac/dc adaptor' 500mA, i've set it from 6v through to 9v with the same results (voltage regulator becomes boiling)

hi, i recently built a core module which does nothing on start up, the voltage seems to be right in all places, the pic was preburned with mios v1.9c, but when i turn the power on all that happens is the backlight switches on, i get nothing over midi and no characters on screen. i'm a newbie when it comes to this stuff, so i'm not really sure what to do, i did notice that apart from the lcd backlight turning on, IC3 (7805?) and the back of the lcd gets very hot any suggestions/help would be appreciated... thanks ash
