  1. mb6582 fan.... Am I mad to unplug it?

    Is the Fan powered by 12v? Than I would use 5V to be on the save side if it´s summer. The oldskool PC Fan silent mod...
  2. Mbox SID LCD "freezing" because of Bankstick?

    Unfortunately, not solved. Looks like there is something getting hot and/or the 5v drops. The freezing happens by playing a patch continously and navigating thru the menu and switching knobs. Or maybe the 165 ICs are faulty... In standby nothing freezes.  I just ask if maybe someone knows this issue, I´ll hopefully figure it out, sooner or later.   EDIT Seems to be that problem, found under MB SID Troubleshoot LCD freezes immediately or after some seconds, synth still functionalA rare number of LCDs don't support 4-bit access mode properly. This has been noticed on two PLED displays and one VFD display so far, "normal" HD44780 or KS0066 LCDs are working stable. Sometimes nibbles are swapped, so that the communication with the CLCD driver of MIOS is disturbed. 4-bit mode is required, as pin RB2 and RB3 are used for the CAN interface. If you notice such an issue, you could activate the alternative "custom" LCD driver, which is already part of the MIDIbox SID V2 firmware. It uses 8-bit mode by using two pins on port E to replace the two pins being used by the CAN. LCD pins D0 and D1 should be connected to PIC pins RB0 and RB1, and LCD pins D2 and D3 connect to PIC pins RE1 and RE2. The driver can be permanently activated via PIC ID Header (LCD type 7, see also Bootloader page), or by activating the DEFAULT_USE_CUSTOM_LCD_DRIVER switch in the setup_*.asm file But if this is the case, how do I connect the CAN?
  3. First I have to told you that I am using 2 Banksticks, just the first(A0 512) and the last(A7 256) I did this to store ensembles in the last one and it didn't seem to be a problem. Both BS are recocgnized, for the last I just have to scroll trough the empty banks. This seemed to be all working fine til the point I play the patch via Menu and scroll between the patches in the first Bank. The LCD freezes (and it looks like the whole Box freezed) but the sound is still playing and I can still change the patches via the Jogwheel/poti. For recreating the issue I turn the Mbox on and play with the Menu, if I plug out the Bankstick-module, nothing freezes. 
  4. Affinity designer Ipad - using for panel design?

    Solved, either they implemented it with the last update, or I was to stupid to scroll. Now it's a perfect app for designing cases or panels without an ipad.
  5. Hello, someone use it? I can't choose cm in the document setup, it just shows, yard, foot and inch...Am I stupid or do they did not check that there are just 3 countries on earth which don't use the metric system?
  6. Mbox SID LCD "freezing" because of Bankstick?

    Nee das is nich das Problem steht auch auf der Bankstick Seite, lag doch an meinem DinX. Solved, Bankstick not the problem, seems like some bad DinX contacts 
  7. midiphy SEQ v4+

    Btw someone is selling one at the fleamarket
  8. Looking for tight / heavy encoders

    You would have resistance :)
  9. Looking for tight / heavy encoders

    Have you tested the detendend versions, too? 
  10. MB SID classic with 4x20 LCD setup question

    Thank you, it´s still a cardbox with cables and pcbs but I´m so glad all connections work...
  11. My MBSID is now ready to work. Unfortunately I found out now that a 4x20 lcd is just supported by the wilba and the classic mbsid just supports a 2x20 by default "fimware" (Its also cheaper than a 2x20) I still struggling with programming, I tried to setup the win7 chain but I stucked as I couldn't activate some plug in settings as described and gave up. I want to set it up at my mac but I'm not sure if the manual is still working with mojave. Some things are also not clear to understand for me. Do I just have to change the program line for initialising a 4x20 or do I have to crawl in the wilba code and copy/redesign the lcd code for showing up all the stuff? If it would be so easy to just change a line would be someone so kind to edit the code for me? 
  12. MB SID classic with 4x20 LCD setup question

    Ok, that means I really just have to change some lines but as I said I did not get the program chain working and I don't really know if I need to install all the stuff because this looks like installing stuff for realtime editing via mios studio. So I thought I just could open the asm file with the microchip ide and I need to include some files... Whatever, one other way I imagined was to translate the lines to hex and just exchange them but this did not work because the translation was not "satisfying" But if this the one and only way as it is described in the mios manual and still not obsolete ok, I will try to go trough this hell, again. 
  13. [MIDIbox SID v2] DIN module map trouble

    It is normal that the Menu behaves like a "back" or more like an "escape" key.  I don't know why the others won't work.
  14. [MIDIbox SID v2] DIN module map trouble

    18f452 is for sid v1 Have you checked if all connections are good? If you use more than one dinx than built one more and check again.
  15. MIDIbox SID Walkthrough

    I own some stacks of the old one sided pcbs from mikes-midishop (the same which are pictured in the documentation) but not the wilba. But shipping inside eu isn't that safe anymore and expensive, too. I have just a good feeling by shipping inside germany.  It depends on your design. It's possible to mix the sids as you want but you need 9v for the 8580 and 12v for the 6581 and 1 core can manage 2 sid modules (left and right) so both sids get the same controller values. If you want that they work independed, you need a core for every sid. The wilba pcb is a system of 4 hardwired cores and 8 sid slots. I suggest to get a swinsid and if your setup works, you can get and test sids.  A swinsid is close to a sid but not 100% like a real sid. But cheap and you can use it as 8580 or 6581 by jumper setting. A 8580 is the newer sid and more precise The 6581 sounds more dirty and has more bass

    Probier mal die zu kontaktieren ob sie dir die alte IDE geben können, oder hier im Forum auf englisch fragen ob die Jemand rumliegen hat bzw. in anderen Foren zB Mikrocontroller.net

  18. MB 6582 Final troubleshooting; encoders and presets

    Have you tried it without the SID?   
  19. OPL3 made in China

    Try it if you can risk 8$ ;)
  20. MB 6582 Final troubleshooting; encoders and presets

    Are you sure your SID is at full health? I've got a 6581 with close symptomes but this shouldn't explain the encoders behavior...
  21. asm to hex

    Yes, I do understand this, it's no accusing, it's complaining ;) It's not easy to understand and research this in a few minutes, it does need a lot of research...and you don't get the answers easy. Sooner or later I must do this, just would be nice to have all the 4 rows of my LCD, now. There is just nothing atm I would change with the inputs.
  22. Nice. I tested the PSUs now in case of noise ratio. I can NOT recommend this cheap China PSU it makes a really loud high noise output but the JAZ PSU doesn't do this, it's pretty damn good, I couldn't recognize that the MbSID is powered with earplugs, just after sending some midi note. Next I will test the power consumption with 1Core LCD and CS stuff, a slave Core and 4 SIDs.
  23. asm to hex

    I'm at the point now to have to change some stuff, too. The official procedure looks very complex and I can't really understand why there is a mplab and there is source code in asm, and can't just edit and compile an asm file, and I think it's because I have to include the files in the project and the question is where...and I don't know why this should be so hard. I don't want to reprogram mios, I just want to change some lines in the code...
  24. This one https://www.ebay.com/itm/120W-Universal-Power-Adapter-for-Notebook-Laptop-In-Car-DC-Charger-EU-Plug-bvg/303062986910?hash=item468ff6309e:g:w-UAAOSw-1ZcZmcc Pretty much overpowered, but just 1A at the 5v. I also have an old psu which offers 12/5 (0,75/1A), which does more fit the needed power  (could be a lil bit underpowered), it's the psu for an Iomega Jaz drive. At ebay someone is selling them in germany but with shipping 30€ As I wrote, I can't recommend those psus at this point because I did not tested it in all ways for a mixed sid setup, I just powered the core and one sid module. Yes, I use the 5v directly to feed the core and the 12v for the sid.  So the only thing what is to do, is to regulate the 12v to 9. Should be also no problem, but can't say this for sure. I read a thread a few days before here, where smashTV, I guess, has written some words about that there are newer voltage regulators out there in case of having more psu options, today and also describes which capacitors can be removed/changed. Can't find this thread again but just looked inside the sid section.  
  25. Well, would be better he also paid the shipping if he sells broken psus, but maybe you can get some bucks for the broken one. May you also have seen that there is a polish company selling new c64 psus on ebay (maybe not in usa), but those are really expensive. It's unusal that they deliever less volts than 5, normally, if the 5v rail is broken (regulator), it delievers more than that and kills everything inside the c64 what needs just 5v. (rip sid) Thats why c64 users today building "crowbar" protection stuff inside their psus and the community is still fighting each others solutions. As far as I read the last times... For a c64, a combination of a 9vac and 5v psu is an alternative and usual but I don't want to contradict latigid on, in case of a midibox you generate 20v ac by a magic act of mixing dc and ac, therefore this solution is profen exclusively at this psus. I do have some c64 psus but try not to use them. They may have the best noise ratio, Thorsten wrote, but I want to use a Laptop psu with a 12v and usb 5v rail, it's smaller and you get them for 17€. I can't recommend them at this point, I still did not tested em in mixed mode but 12 for the sid and 5v for the core, works (yeah, why shouldn't...). The question is still what happens by using the 12v for the old sid and transform this rail to 9 for the new sid.
