Hi, perhaps this can help to do it software based: http://courses.missouristate.edu/KenVollmar/MARS/CCSC-CP%20material/Fibonacci.asm Best regards, clem! Randomness is an Illusion

Na gut, ich hab dann mal selbst recherchiert: pauschal (zumindest bei kleineren Bauteilen) fallen Kosten von 10 USD an und sie wollen Informationen über das Projekt haben. ich hab dann mal noch ein paar andere (billigere) Quellen aufgetan: http://www.futureelectronics.com/en/Technologies/Product.aspx?ProductID=MMA1260EGR2FREESCALESEMICONDUCTOR1827393&Language=en-CA und dieser mit xyz-Achsen (läuft allerdings nur auf 3,3 Volt) scheint auch interessant zu sein http://www.sparkfun.com/commerce/product_info.php?products_id=9652 EDIT: ok dieser hier scheint vielleicht noch interessanter, auch wenn es bereits ein älteres Modell ist, aber 13 EUR und ich brauch das Ding mit meinen alten Augen ;-) nicht löten: http://www.lipoly.de/index.php?main_page=product_info&cPath=880_883_885_887_1339&products_id=11391

Hallo, hat jemand von euch schon Erfahrungen mit Freescale Samples? Fallen da Kosten an, wenn ich Samples bestelle? Porto und Verpackung etc. Bei Micromaus gibt es den hier: MMA1260D für 20EUR - zu teuer, wenn das, was ich vorhabe, nicht klappt. Schöne Grüße clem!

Hi all, look what I've found yesterday: http://www.conrad.de/ce/de/product/425664/3D-JOYSTICK-F-POTENTIOMETER-M-SCHALTER/SHOP_AREA_17440 10 kohms (mini-)joystick for EUR 1,43 with or without switch Best regards, clem! Edit: SOmeone else found it earlier ;) -->

Hi, and welcome to the board. I don't have experience with the sammich but some month ago I've build a midibox sid. I have tried some different encoder types and had to adapt the firmware for different encoders. More about encoders you will find here: http://www.midibox.org/dokuwiki/doku.php?id=encoders#rotary_encoders Sometimes if you have cheap encoders there is a larger span of inaccuracy in the mechanic of the contacts. Perhaps a little adaption of the firmware or the exchange of the encoder can solve this problem. Best regards, clem!

Hallo Wolfgang, hast du die Möglichkeit den Midi-Datenstrom der bei dem Expander ankommt zu loggen und mit dem Datenstrom der ankommen sollte zu vergleichen? Das sollte, wenn du keinen anderen Mac hast, auch mit dem Atari gehen. Entweder fehlen dann komplette Midi-Messages oder die einzelnen Midi-Bytes/Bits sind fehlerhaft. Im ersten Fall würde ich auf ein Software/Treiber/Konfigurations- Problem und im zweiten auf ein Hardware-Problem schließen. Ich würde mir an deiner Stelle auch noch einmal Midikabel und USB-Kabel von jemand anderem leihen um hier Fehler wirklich auszuschließen. Schöne Grüße und viel Erfolg clem! eigentlich hat das ja mit MIDIBOX nicht wirklich was zu tun ;)

Hallo, hast du Übertragungsprobleme und Kontaktprobleme ausgeschlossen? Wie lang sind deine (Midi-)kabel/entsprechen sie den Spezifikationen? Hatte vor Jahren mal ein ähnliches Problem, da lag es an einem selbstgefrickelten zu langen Kabel. Schöne Grüße clem!

Hi Frank, if the LCD isn´t used I would first try to use another PSU - some LCD-Backlights need more power than someone suggests. Best regards, clem!

Hi, Which voltage does your psu have did you wrote 39V or 3,9V? Ideal would be something around 7-9 V dependent on stabilization of the PSU, if you want to get stable 5V. Best regards, clem!

hi all, don't know why I missed this thread. After some earlier searches I think the cheapest way to get usable hex-buttons would be to take wood and glue it on the caps of the buttons eventualy those of an old (min. 20 years) computer-keyboard(?)have a nice feeling. I like also this one http://musicscienceguy.vox.com/library/post/how-to-build-a-jammer.html scroll down this is velocity-sensitive. Best regards, clem!

Hi, it depends on how you want to implement it. -if you only want to shift the notes of the mbsid you want to implement you can add one or two buttons and patch the code so that the incoming midi events are altered by twelve halftones up or down -if you don´t want to add buttons you have to expand the menuestructure of your sid which seems to my mind a little bit more difficult. -third possibility is to add an extra core as masterkeyboardcontroller and add a nice user interface with extra controllers, a big display etc and then share a well documented code :) Best regards, clem!

Hi, what kind of psu are you using - I would test another (bigger) one. if that doesn´t help - try to lower the powerconsumption of your midibox by unplugging the sids (if they are in) and unplug pics 2-4. Next step I would do - is to check all the solderpoints of the resistors and parts around the optocoupler and perhaps resolder and/or exchange them - if you haven´t done that yet. Check the contact of pin 26 of the pic - does it have contact? Try to measure the powerer consumption during your upload attempts - what does your multimeter count? Have you tried to change the pic? Best regards, clem!

Hi, is it possible that you have unstable power? I had some funny problems with my unstable psu lcd combination. I allways had to unpluck my lcd when I wanted to upload something to my mbsid. At the end I switched of the lcd-backlight. Best regards. clem!

Hi, Did you read the right things? http://ucapps.de/mios_bootstrap.html You can read it in french or spanish, too. If language is the prob - try google translation - sometimes funny - but often a little helpful. Best regards, clem!

Hi, did you load up the firmware to the pic(s) or any one else? Does the pic send an update request via midi? Best regards, clem!

Hi Julien, eventually this can help: http://sounddoctorin.com/synthtec/parts/key.htm You will find pictures there. Best regards, clem!

Hi Astazou, for a starter project this seems to be a very big project. I would recommend to split this into 3 or 4 smaller projects! I think that midifying an electronic-organ was not the main intention of MIDIO128 but to midify mechanical-musical-instruments! So if you are able to programm your own firmware you should use (as nILS told above) a matrix to scan the manuals. Eventually as the first project and then expand it with MIDIBOX64(E) as controlsurface. Best regards, clem!

hi, ucapps - search mb-sid v2 walkthrough - read and find out which modules make a sid. As told above more sense than to study schematics would it make to check the well-commented assembler-code. Best regards, clem!

Hi numbed, do you really need a schematic for 14-16 momentary push buttons and 56-64 LEDS connected as matrix? I´m sure all you need, you will find here --> http://ucapps.de/ Well, I think the more difficult it´ll be to programm it ;) Best regards, clem! EDIT: *Erster :)*

Hi all, I know this isn´t a project for me - first finish your unclosed keyboard- and sid- projects - learn asm - study dsp-programming - etc. just want to share the idea: http://www.wavefrontsemi.com/index.php?products http://www.axoris.be/VirtuAL3101.php http://www.wavefrontsemi.com/products/AL3101pop.html Best regards, clem!

Hi, I for example would be interested in 6581R4ARs as shown in the pic (pic of the bottom side will follow). One pair of them is working in my Low-budget-MB-sid if I could find 5 others I would expand it and the third one could do some productive work ;) . Best regards, clem!

Hi all, as I understand it right it´s not such agreat prob to find a pair of 6582 or 8580 that fit together from their sound. If u have luck and find more than one 6581 from the same plant with the same production date, the chance that they have the same timbre (means volume and sound) and that they harmonize with each other is a little bit greater. So here comes my idea, what about a little SID exchange: If someone has spare SIDs or is searching a special production line or date one can post it here - so that everybody has the chance to get pairs or octetts of gout sounding ensembles :) Best regards, clem!

Hi Seppel, if u like those old electronic instruments u´ll find here some more old cool electronic stuff: http://120years.net/ Best regards, clem!
