  1. design questions

    If you have to switch between the modes very often, I could compile a special version which allows to select the mode with the spare pin (J14 of the core module). In this case, you have to connect a 10k pull-up resistor between J14 and +5V and can select the to-COM option by using a jumper to ground. I have to test this version, because I don't know if it already works correctly. You will get it next week (I'm not at home and currently have no access to my source files). Best Regards, Thorsten.
  2. It would be great if somebody could evaluate the quality of this programer, just to save my effort. I already own the PICstart kit by Microchip and therefore have no problems to program the newer PICs... Best Regards, Thorsten.
  3. Hallo Andre, eine Liste findest Du unter Die unterschiede zur Original-Schaltung sind dort ebenfalls aufgelistet. Welche Bauteile fehlen Dir denn? Gruss,        Thorsten.
  4. SOS! kein MIDI OUT

    Hier treffen zwei fehlertraechtige Dinge aufeinander: a) Onboard Soundkarten werden von den Boardherstellern meist recht stiefmuetterlich behandelt und sorgen immer wieder fuer Probleme. Aber vielleicht ist ja nur der MIDI-Interrupt deaktiviert, das wuerde zumindest erklaeren, warum der MIDI-In Deines PCs nicht reagiert. Ueberpruefe mal im BIOS-Startup-Menu unter "Onboard Peripherals", ob dort der entspr. Interrupt freigegeben ist. Defaultmaessig steht der Schalter sicherlich auf disabled. b) Windows XP. Probiere mal den Roland Driver aus, der funktioniert angeblich besser mit den neueren Wintendo Versionen. Gruss,        Thorsten.
  5. Sequencer Question

    just wait until the sequencer firmware has been seperated from the MIDIbox64 controller - with this step a lot of new possibilities will be available :) Best Regards, Thorsten.
  6. Midio 128 -Thanks .. but help !

    Hi David, you can configure the events with the script and send it to the MIDIO unit with Serges "vsysexbox" from I just noticed that this isn't well documented, so I will add some comments to the MIDIO128 page. Have fun! :) Best Regards, Thorsten.
  7. Midi Merger

    Hi Jurie, I've no idea, why the integrated merger of MBPlus shouldn't work with the same hardware. It would be interesting if the interaction with Serge's editor works correctly: connect the MIDI Out of your PC with the MIDI In of the MIDIbox, start the editor (, and click on the "Request Dump" button. Does the program receive any data from the box? Best Regards, Thorsten.
  8. Thanks for the input, I've added a comment in the README.1st, this was the fastest solution. Best Regards, Thorsten.
  9. you really want to disable this unique feature of the SID? Shame on you!  ;) Best Regards, Thorsten.
  10. New MotorFader design

    To all beta testers of new circuits: please check the consistency of the PCB layout, the schematic, the part lists first and tell me any differences. Simple typing errors can cause a lot of trouble...  :'( Best Regards, Thorsten.
  11. New MotorFader design

    Hi Frank, Damned! Not a LM7812, but a LM317 has to used, otherwise the voltage cannot be regulated correctly. Sorry about this, I remember that my schematic program crashed during I drawed this diagram, thereafter I had to made it again with less motivation - on this way I forgot to update all copy&pasted part values. :-( So, your MIDIbox MF will work much better with the correct voltages, with > 10V the faders will be moved too fast, so that for example the automatic MIDI feedback elimination routine (which prevents the effects you descriped) will not work correctly. There is no way without the LM317 - correct fader movements can only be guaranteed with a clean, stable voltage. Best Regards, Thorsten.
  12. Cap value???

    Hi, yes, it's a 100nF cap Best Regards, Thorsten.
  13. Bankstick question

    I think so... Best Regards, Thorsten.
  14. Led question...

    Hi Christoffer, both is correct (ok, the (-) voltage level is named Vs and not Vd) Best connector for the power LED + resistor is J2 of the core module. Best Regards, Thorsten.
  15. design questions

    If you need a dedicated firmware with MIDIbox-to-COM enabled by default, just request it via mail. There are already existing a lot of non-published MIDIbox variants (I just counted it: more than 64 variants! ;-) and I don't want to compile them with every new release, since on this way I would also have to test the variants by myself to avoid any trouble... :-/ Best Regards, Thorsten.
  16. Hi, the answer is simple: the SID firmware will handle the control surface, so take one core module to drive the SID *and* the control elements, and attach other core/SID pairs to the first module via MIDI or MIDIbox Link as slaves. I'm currently not sure if the surface should have only LEDs/LCD/pots/buttons, or some additional encoders, or some additional faders, or some LED rings. So please understand that I don't want to make any statement regarding the reuse of modules for the SID surface. You can only be sure, that I will not redesign modules which are already established by the MBHP just to have a more elegant solution for the MIDIbox SID. Btw.: I will evaluate my ideas for the MIDIbox Link next week, thereafter I will create two new pages: one page which describes all the possibilities, how to interconnect MIDIboxes to other MIDI instruments or boxes (MIDI In/Out, Gameport, RS232 and MIDIbox-Link), and another page which gives more details about the MIDIbox Link itself, the protocol, the possibilities. Best Regards, Thorsten.
  17. sysex for snap mode in MB16??

    Hi Bosone, no sorry, this isn't possible, since the MIDIbox Plus is designed for 4k PICs, I had to reduce it to the most important and requested features. If I would integrate a sysex string for switching the pot mode, I would have to delete another function which would make other peoples unhappy :-/ However, you should be able to select the modes "blind" without andisplay, the necessary sequences are (after Power-On): Pot menu: Exec-Right-Right-Exec (see the MIDIbox Plus schematic for the appr. pins) Thereafter you can select the modes with the left/right buttons: Normal/Snap/Relative/Parallax Best Regards, Thorsten.
  18. With the upcoming MIDIbox Link it will (should) be possible to control up to 15 MIDIboxes from on "Master MIDIbox" with one LCD, one row of buttons, one MIDI In/Out pair to the PC. Best Regards, Thorsten.
  19. CV/Gate Out

    The MIDIbox SID will get an AOUT interface with a 4-channel 12-bit DAC and 8 trigger outputs in the future. Of course, the firmware can also run without the SID itself, on this way you have nice CV interface with additional virtual LFOs, EGs, slide, arpeggiator, and so on... :) Best Regards, Thorsten.
  20. No, I didn't forget the drum pad option, I just decided not to implement it, since Admir already did it in his edrum project. Why should I reinvent the wheel? ;-) Best Regards, Thorsten.
  21. Since I also need this possibility sometimes, when I want to duplicate the stored pot setups, it's on the ToDo List now. Best Regards, Thorsten.
  22. Newbie Question

    Some menu options (e.g MIDI Learn and Encoder Mode assignments) can be already controlled by the encoders, for other function it isn't really necessary. Btw.: In the next weeks I will release a new MB16E firmware which allows to select one of 128 parameters for every encoder seperately on the fly - intependend from the current bank by pressing a button and just turning the encoder to which the parameter should be assigned to. During the selection, the parameter name will be displayed on the LCD. In a later version, it will also be possible to group encoder assigments. I think that this will result into a very efficient usemodel for (software) synthesizers. :) Best Regards, Thorsten.
  23. Holidays (again)

    I'm on vacation for some days, please link together on problems and questions regarding the MIDI projects. :) Best Regards, Thorsten.
  24. Weitere Ideen

    Ideen sind angekommen :) Sobald ich den Sequencer erstmal von der MIDIbox64 firmware separiert habe, kann ich solche Features beruecksichtigen. Momentan werden noch die MIDI-Events fuer alle 64 pots gleichzeitig im RAM gehalten, das verbraucht 128 Bytes RAM. Ich moechte das Handling aber so abaendern, dass die Informationen nur bei Bedarf (kurz bevor sie benoetigt werden) aus dem internen Flash, bzw. aus dem externen BankStick geladen werden. Auf diese Weise lassen sich a) wesentlich laengere Sequenzen, b) mehr Variationen, c) mehr Tracks gleichzeitig, d) einen Super-Combined Mode mit Wahlschalter fuer Notenhoehe/Velocity/Gatelength pro Pot-Reihe, und noch vieles mehr realisieren. Mutes sind uebrigens schon sowohl fuer die einzelnen Tracks, als auch fuer die einzelnen Pot-Reihen moeglich - aber auch das wird dann noch erweitert... :) Gruss,        Thorsten.
  25. SOS! kein MIDI OUT

    Hoert sich so an, als wuerde die Spannung einbrechen, die sollte immer konstant auf ca. 5 V (+/- 0.2V) liegen, auch dann, wenn man an den Pots herumdreht. Wieviel Strom liefert Dein Netzteil maximal? Und funktioniert es vielleicht besser, wenn Du das Backlight erstmal abklemmst? Gruss,        Thorsten.
