  1. for now I'm not sure if "junk-CCs" are sent because of mechanical (soldering) issues or program issues. from one hand - it worked well after reloading program - even after few on-offs, but after day or two without power - I run keyboard and junk-CCs appeared again. From the other hand - I moved keyboard from one place to another. So - it can be something with chip, with connestions and with program.... Got to check it somehow... but it looks that I need few more days, because I have hard time in my office.
  2. yup, I have multimeter, but I'm affraid that I'l have to get electronics out of the box. It's hard to visually controll all the connections, especially these analog ones. It's not "elegant" construction, so some pins are soldered with "shortcuts"
  3. especially if I'm rookie, right :) as I mentioned above - first of all I will check connections, because I've seen somewhere on uCApps that accidental communicates can be sent if some free inputs arent grounded or something like this. It will take a while, cause I have to unscrew CORE and DIN and DOUT modules and take them out the enclosure. I can only guess, that there is something wrong concerning analog inputs, but I can be wrong. Maybe you have an idea what's up? Next thing is to find where in code (and in which file) I can define mIDI channel for outgoing MIDI messages from controllers.
  4. Keyboard itself and Sustain work great - and keyboard and Sustain are on DIN and DOUT. But I still have troubles with MOD, AT, PB - and these controllers are cinnected to analog inputs (J5) I've fouynd some code lines concerning PB, MOD and AT - in MAIN.ASM file. those controls are connected to analog inputs. It seems for newbie that everything gonna be OK, but I can't find description, where to change MIDI channel of "Fatar pitchbend", and... I don't really know what's wrong with these controls - they still sending accidental values. I fixed itself after reloading program, but after 2 days of not being Maybe problem isn't in the code but in the CORE itself, or problem is somewhere in connections? I wanted to try latest MIOS to compare if theese errors will still appear but I'm affraid thar original program wil not work on higher version of mIOS. And I don't have MIOS 1.5 to load it back in case that program won't work on MIOS 1.9. Any sugestions?
  5. Jim, I understand why I had to change only one number, I'll show you: In this example - what was very important to me - was changing value from 64 (HEX: 40) to 127 (HEX: 7F) but SUSTAIN is #CC: 40, so changing every "40" value into 7F did not gave me expected results, because somehow I changed #CC: 40 into #CC: 7F. What I finally did was line: I more-less understand why only this line - because it defines value that will be sent if SUSTAIN go to state 2 (pressed). I can (for now, because I have no Assembler skills for now) only assume, that lines: just determine #CC of controller. What I was looking for in meantime (and I'vefound it a week ago but I can't remember where) were lines with controllers definition. Next issue is that PitchBend (Roland Pitchbend - it's described like this somewhere in the code) in farest left sends accidental SysEX values like STOP, START etc (MIDIOX shows those values), and in farest right - it sends "G19 NOTE OFF".... totally weird. Moreover I want to change two things: 1. PitchBend WHEEL works on CH 3 instead of CH 1. 2. I want to change PitchBend WHEEL into #CC: 2 (Breath Controller) Later I have to check what's up with code or CORE, because I DID ERROR-FREE loading several times, I made few ON-OFFs, and keyboard was running great, but yesterday I had issues like in first post: - PB and MOD was sending acccidental values (mostly 0)..... Jim - is there another way (newer core?) to try to make this project simpler?
  6. sO FAR SO GOOD: 1. i HAVE lcd 2. i made ONE change in code - so now SUSTAIN sends values 0 and 127. good :) 3. after reloading program - accidental PB MOD AT values sending - dissapeared. :) now - another issues. 1. check AfterTouch. There are two strips - one for white, one for black keys. AT on black keys don't work. 2. After extremly pushing MOD lever, it sends SysEX too! and "g19 NOTE OFF"... WTF?
  7. TODAY, in Polnad we have New Year Eve.. so I go t work (party DJ). For now I'm getting familiar with code, moreover yesterday evening I had smal "session" with constructor of this keyboard, so I hope from 1-st of January I start first modification in code and debugging to check what's wrong with AT, Mod and PB - is it software or hardware problem, because constructor swears, that he had no problem like this :) We will see.
  8. well, before I go to journey I have to start with first step ;) so I will try both: to use what I have from previous owner, especially that he promised to help me if I'll stuck. and to use up to date version of MIOS Studio. We will see what will happen :) It looks that uCApps comunity is very special, because even on "my" forum, where I'm one of moderators, you won't find so helpful people sometimes. Maybe, when I'll learn more, I'll try to make little add-ons and modify/update some lines in code, but it's song of future. I concern is it worth to add more controllers (LCD, program/bank change buttons or dialer, free assignable pots and buttons), or leave it as it is - a great hammer action masterkeyboard only.
  9. Jim, Keyboard project is operational, with some bugs I described above: main issues are PB, MOD and AT controllers. I would like to change Velocity response too (for now it starts from value +/- 20 instead of 1), but in this point it's not as important, because it works good as it is. Thank you very much for help in finding Sustain lines, Now I have to make changes in code, compile it and load to CORE. Which one MIDI Studio should I to use? this one in attachement (few post above) or this one from uCApps download?
  10. Thanks, I've was thinking it's just a simple setup with Sustain, somewhere in code (setting min and max value). About a project - in a fact this is projest from CuBase I think (I don't know if this guy is present on this forum, but I can suppose that this is the person. He told me he had problems with this project, tears blood and sweat. Project is almost done, most irritating things are PitchBend, Modulation, AfterTouch. While PB and MOD wheels are doubled, so they go crazy if one PB is set to "0" and second is higher/lower; AT just acts like sending impulses of "0" and "actual" value. I will try to record it at home.
  11. Believe me, I started to read uCApps a week ago - just maybe I'm not patient enough. Thank you for help, give me few more days - I wait for some stuff coming after Christmas - LCD, cables, etc.... And I'll let myself gto write here, ok? ;)
  12. for now I know that inside is CORE on PIC, DIN and DOUT only, I have code for this keyboard, compiler and loader, but still it's black magic for me :-/ I can send you code, compiler etc if you would like to see it.kompiler.rarsm_16x16_fatar_88wood_V2009.rar
  13. You're right. Sory I had no time for answer, I had "hard days nights, when I was working like a dog".... For now, I have MIOS Studio already, I wait for LCD - one question - If I understood the description, I have to find 2x16 LCD? not 2x20?
  14. Thanks for replay. I read ucapps.de and try to understand basics, I'm not (believe me) one of those people, who don't want to know, just want to get instant answer. More Photos - I'll do it in the evening. But there's nothing more to show. It look like it's simple project: 88 keys keyboard with dynamic and aftertouch, MIDI IN and OUT, Pitchbend-Modulation lever, PitchBend wheel, Modulation Wheel, Sustain pedal input..... no LCD (I will buy one - 2x16 or 2x20 characters?), no more pots or sliders. I'm from Poland On photos you can see all the PCB's inside enclosure. there's nothing more than one core PCB and two "matrix" PCBs. It looks like they are AIN modules (or DIN modules????), connected stright to keyboard and to Core module.
  15. What I have inside is: - 1 core board - 1 MIDI IN-OUT board - 2 boards with incoming signals from keyboard and controls: - 1 Roland style PitchBend-Modulation joystick - 1 PitchBend wheel - 1 Modulation wheel - Aftertouch (from keyboard). What is wrong: - Aftertouch values jump between 0 and actual pressure - the same for modulation (it looks like lever and wheel are generating values even in "zero" position) - the same for pitchbend What I want to add: - Expression pedal Unfortunatelly I don't have any idea how to make changes I need, it looks like a magic for me.... I want to learn how to do it, but I desperately need help in first steps with this project.
  16. I know, but for now I have to get rid of what I have... It's build on PIC18F452 so I assume it's old project. It has only MIDI IN and OUT - no USB. http://www.ucapps.de/mbhp/mbhp_core_v3.jpg - it looks like this one... Previous owner said that he can give me a LITTLE help, but he sells this keyboard "as is". So for now I have to solve few very important issues: 1. doubled PitchBend and Modulation controllers don't work properly. It looks that value depends on how far joystick AND wheel are moved. When one is on nominal - values jump 0-max on second controller. 2. "near zero" values are generated all the time - it's quite uncomfortable especially when I look on it in my DAW 3. Sustain pedal generates 0-64 values - it HAS to be 0-127 4. Aftertouch values jumps between 0 and maximum pressed 5. minimal Note ON value is more-less 20. So there is no very pianissimo. For now it's not important but near future I want to recalibrate all the keys to achieve values between 1 and 127. I don'n know completly what program should I download to have ability to change these bugs - and even more - I totally can't do it by myself..... I have two friends only who could help me, but one of them lives few hundreads miles from me, and second is previous owner. I need serious help, because keyboard is great and I want to keep it, but I have to get rid of these bugs. Can you - or anybody here - help me?

    Poland.

    Ja z innym pytaniem - właśnie dostałem klawiaturę - bajerek - z elektroniką na MIDIBOX. Teraz chciałbym nieco ją przeprogramować i zmodyfikować, niestety nie bardzo wiem jak się za to zabrać. Klawiatura jest uruchomiona, ale jest jakiś zonk z komunikatami wysyłanymi przez zdublowany pitchbend i modulation. Poza tym przydałoby się zmienić czułość klawiatury, bo w tej chwili minimalne wartości Note ON zaczynają sie gdzieś koło 20-30. W zamierzeniu chciałbym dodać: - dialer do Program Change - przyciski Pgm UP i DOWN - może kilka pokręteł, ale nie jakoś fanatycznie - gniazda na dwa footcontrolery: Volume i Expression - gniazda na 3 footswitche (w tej chwili jest tylko sustain) Prawdopodobnie od poprzedniego właściciela będę miał jakby co "wchuuuu" gratów do miiboxów, bo ma tego dwa pudła. ylko on sam pewnie nie wie co ma. Gdyby ktoś pomógł określić, co potrzbuję jeszcze, jak to podłączyć i - jak to potem podprogramować... Stawiam dużą flaszkę albo i trzy :) Będę wdzęczny za wszelką pomoc. Idealnie gdyby ktoś mieszkał w Wawie lub na linii na Otwock. poniżej linki do fotek: http://img248.imageshack.us/img248/643/201112041208022.jpg http://img856.imageshack.us/img856/7731/201112041210023.jpg http://img59.imageshack.us/img59/1683/201112041211024.jpg http://img26.imageshack.us/img26/8161/201112041203016.jpg http://img337.imageshack.us/img337/3212/201112041204017.jpg http://img248.imageshack.us/img248/8716/201112041206018.jpg http://img217.imageshack.us/img217/3825/201112041207020.jpg
  18. i got MIDI keyboard from my friend, inside it looks like this: http://imageshack.us/g/248/201112041208022.jpg/ What I ned is help with programming and transferring via MIDI (if it's possible). Issues: - I want to redefine "zero point" for note-on (for now minimal level is +/- 30) - redefine modulation wheel - add Expression pedal in future: - add Program Change up/down buttons - add inputs to get 2 pedals / 2 footswitches / 1 sustain please help the newbie :) thanks, Adrian
