Hi everyone, I'm stuck in the powering issue. Does anyone tried the solution described above (15v to mf module and 15v through 7809 them 7805) with success? I was thinking to buy a 15v 3A wall adapter to power a full mbLC

well obviously NOW is clear :D got to find some sparetime to learn some programming :o Hey thank you very much for clarifying :D

well, too late ;)

Hi alex, I made the same question on another topic, but having no great experience in programming I'd like to know if you had luck with that issue.

Never experienced problems using my midibox with Live.. Check out the midi interface, I'm using a midex 8 and it works perfectly except for a driver or Windows bug which make mios block when no midi ports are opened by software in the interface and I connect the midibox to it

Good Thorsten, as it sounds I can say without doubt this is the chip used in Chroma polaris ;) -------> although CEM3372 I checked out the service manual of the old fender synth. Maybe some hardware could be taken as example for a mios polaris based synth :D

as smash says: best!

sorry fanir I've no clues, I built a JDM photoetching a presensibilized pcb using the eagle layout in ucapps.de and it worked immediately, if you're not skilled in soldering I do not recommend building it on a breadboard; in case order a etched pcb from someone who does this service

very 70's style congratulations

yes it happened to me, but it was related to my firewall, check out for conflicts

I have the same problem with a pic18f452, All tests are ok, but the problem occurred only with that pic. I succesfully burned that pic 6 or 7 times, now I can't erase with IC prog the content (icprog says address 000H, the first, is not blank even after erasing the device and when I read the content there is a mass of random data in the eeprom too). Thorsten, is it possible that I damaged the pic by copying applications via Sysex after having uploaded other apps (for example, I burn the bootstrap, I send via sysex mios v1.8 and then mb64 app, then I upload mb64E app without erasing the device from the previous application)?

yes you can connect up 8 pots to J5 but you need to run the application in unmuxed mode (check main.asm file with mplabIDE)

thanks moebius :D still in debt for lcd troubles issue you helped me to solve time ago ;)

I don't recommend the use of psx joystick buttons as they are of relative low quality (rubber switch) and difficult to install on a panel without precise drilling on the panel. Hey moebius you showed up :D could you tell me what do I need to modify on the main.asm file of midibox64 to reduce deadband of ain driver?

The MB sid control surface allows only encoders (DIN's) as far as I know, but people have used joysticks from Elfa and from Alltronics so I suppose the answer is yes. The problem is that these sticks are not precise (Thorsten wrote high resolution 10 bits AIN drivers) so the central position is different each time the stick returns to the centre. Some code or change in main.asm is needed. Does anyone know a solution?

Hello everyone, I stuffed an analog stick you can easily found on old PSX dual shock joypads on my MB. It works very well, except for a mechanical issue which cause the stick not to come in a precise central position, so I have values oscillating between 60~70 (CC). I thought this happens because of AIN driver sensitivity to slight changes in the wiper voltage. How To obtain a precise return of the stick to value 64? Maybe reducing AIN deadband (where do I need to modify the main.asm to reduce deadband?). Thanks in advance

Thank you. that used midex 8 will be handy ;)

A core with 8 motorfaders needs a dedicated midi in and out. If I connect 2 cores via MBlink for a total of 16 MF I need only one midi in and a midi out or do I need to build separate midi in and midi out for the 2 cores? Does it work like the original Mackie control extension since the protocol is the same? Well, maybe someone else gave an answer on the forum to this question but I didn't find it, so sorry for the redundance. Thanks in advance

Thank you Pilo! Again congratulations, I can't immediately work on your project since I'm busy with my MBLC right now, I can't express my gratitude for all the infos and input you're giving me ;)

aren't them 8 channels mono?

Well I'm beginning to understand your design. Very cool! Congratulations. But: In the buffer module description you state for ADC connectors: "there are 4 connectors for 4 adc boards (...)" If I want to use the 8 adat channels at 48Khz, I'll need 8 ADC's to have 8 analog channels in 8 adat channels. How to connect 2 adc's to a single input in AL1401? In other words, how to stream 8 channels in the AL1401 which provide only one pin for channel 1/2?

Sorry pilo I bothered you enough, but I found a post belonging to you in http://www.midibox.org/forum/index.php?topic=2738.0. Which PSU did you use for the ADC/ADAT? a 286 AT or a pentium ATX? what about noise on analog preamps?

actually it is 20% for the mafia and 5 % to the state according to non official and sincere stats ;) damned Italy I'm not sure they'll agree with this strategy :) well that was a smart-thinking anyway :D

Thanks a lot Pilo! Some issues: Do you think I need to build a clock generator (I can sync the al1101 and al1401 to my motu hardware which can generate WDCLK) without building a PLL?

Well here's my plan: the motu traveler supports up to adat 8 channel @ 48Khz and 4 @ 96 Khz (conforming to adat protocol) . anopther good thing is that the traveler has WDCLK output. I could make 8 preamps with al1101 ADC streaming to an AL1401 and synchronise them with the word clock output of the Traveler. Do you think I'll need SMPTE sync too or it will be enough sample accurate? I don't know how to sync smpte
