  1. geez, superdavies, that is tough work. Du you understand how a hammond works ? I am not shure if I do but as far as I know does each hammond of the fav models (M3, A100, B/C/RT3) has 9 keycontacts for the 9 fundamentals you are able to mix with the 9 drawbars. A midimessage for "note on" would not only have to contain the midi note (key on the keyboard) but also the mix of the drawbars. For example, the more drawbars are out the more overtones sound, meaning the more tonewheels must be switched by your µC. this sounds like a lot of work and if I were in your case I wouldnt even try. Cause if you are using the keyboard of the hammond you wont reduce weight as the keybeds of the hammonds are real heavy. I would try to build a midibox with some lighter keybeds like Fatar's TP/8O and real drawbars from your pool of parts and let some digital gadget produce the sound or use the REAL thing.

  2. Moin. Ich hab ein Schaltungsproblem, was mich davon abhält mit meiner Midibox loszulegen. Folgendes: Ich möchte 9 Potis doppelt haben, sprich 18 Potis, untereilt in 2x9. Beide 9er Gruppen sind denselben Midicontrollern zugeordnet, z.b. CC 12-20. Die beiden 9er Gruppen sollen dann über 2 Tasten auswählbar sein. Also Taste 1 wählt Potis 1-9 aus und ordnet sie CC12-20 zu, Taste 2 wählt Potis 10-18 aus und ordnet sie CC12-20 zu. So kann ich an den nicht ausgewählten Potis schrauben und sie dann später "scharf" stellen. Und wie soll ich das am besten implementieren. Danke im vorraus borntob4
  3. Du willst das Keyboard vom LMK mit einer eigens entwickelten MIDIBox ausstatten. Klar geht das ! Problem: Du kannst nicht auf bestehende Projekte von TK zurückgreifen, da Velocity und Aftertouch nirgens implemenitiert sind. D.h. Du mußt dich in MIOS fit machen und die beiden Features selber programmieren (O.K Aftertouch ist wohl eher vernachlässigbar einfach, aber Velocity ???). Ich würde dann Deine Frage mit "zu kompliziert" beantworten. Versteh mich nicht flasch, es geht aber wenn Du ohne Vorkenntnisse an die Geschichte ran gehst könnte es was dauern bis Du wieder vernünftig klimpern kannst. Auch auf die Gefahr das ich mich wiederhole: Reparier das LMK und bau Dir ne eigenständige MIDIBox, das wird noch spannend genug. Korrigiert mich wenn ich mich irre, liebe MIDIBoxer ! Grüße aus Hamburg borntob4
  4. Moin ! Also ich an Deiner Stelle würde folgendes machen. Ich würde das LMK ordentlich reparieren lassen (zur Not einfach Platine bei Doepfer als Ersatzteil bestellen) und Dir dann ne MIDIBox für die Controller bauen. Und wenn ich später mehr Zeit hab, kann ich Dir auch erklären warum ich das so tun würde. Gruß aus Hamburg borntob4
  5. Sehr nett, mike&claudia. Da kann man sich ordentlich Arbeit mit dem Reicheltkatalog sparen. Werd mich bald bei euch melden. Weiter so ! Gruß borntob4
  6. "We hope that the organ keyboard (temporary name B4M) will be available late summer 2004. In fall 2004 the control unit (temporary name B4C) will follow." I am not completely satisfied with that solution but for me it is a good compromise for on stage assumed that the keyboard has velocity. You can`t built it yourself for that price because of the waterfall keyboard's price. It liked to have one for my new band (funk soul). But I will say it again: If I would life in the US, I would try to get 2 manuals from an old hammond organ and built a B4 controller based on MIDIbox for home use only. With a nice B3ish wood cabinet, 4 drawbar sets (2 for upper, 1 lower, 1 pedal), a real half moon Leslie switch and maybe a pull out drawer for all other controllers that I don't need so often. Not to forget the bass pedal in order to learn jazz organ. But we all need dreams ! ;) best andreas
  7. I think I will dump all my projects concerning a B4-controller because of that: http://www.doepfer.de/B4.htm We'll see. I would have liked to built it on my own, but the prices are pretty cheap. Best andreas
  8. Take a look at this awesome project. Great work ! http://www.smctek.com/B2MIDIControllerProject.html :P I would like to built something like that, too ! Best andreas
  9. " Question to anyone how wants to answer: In reading different threads on all subjects, I read about presets. I don't know anything about Hammond organs or B4, etc. So what are presets and how does this apply to the organ? Thanks, Johnc" To start with, the Hammond Organ was invented by Laurens Hammond as a substitution for church organs. The drawbars were named after the length of the pipes (16' 5 1/3', 8', 4',2 2/3', 2', 1 3/5', 1 1/3' and 1'). So 9 drawbars were used. You could vary the loudness of the tone (for example the fundamental 8' ) by changing the position of the drawbar (9 positions: 0ff, one to eight). You had 2 sets of drawbars for each manual. And here come the Preset keys: The big hammond console organ with 61 note keyboards (B3, RT3, C3, A100 and similiar) had a special octave of keys. This octave has reverse colored keys in order to make it more visuable. With the b and the a# of the preset octave keys the player switched between the 2 drawbar sets. With the rest of the preset octave you can choose a "Preset". A Preset is a hardwired sound setting in opposite to a set of 9 drawbars. Instead of being connected via the drawbar the Preset keys are directly connected to the tone generator of the organ (setting tone pitch and loundnessof the tone). All Preset were the same at a stock hammond. If you want to vary the Presets you have to rewire 9 cables (using a soldering iron). The B4 is a software program emulating a B3 hammond organ. I hope I made myself clear. If not, feel free to ask. andreas
  10. "The switched resistor scheme above would require cutting the bus at each drawbar and connecting a resistor array at each drawbar. " No, you don't have to. You 're referring to the schematic I've send to you, right ? You need only 8 resistors for one drawbarset. The wiper is connected to the AIN-module and depending on its position a voltage level (/ a resistance value) is translated by MIOS to a digital value. It is already a kind of matrix. If you would own a big drawbarset with the 4x9 drawbars plus 2 drawbars for the pedals and assuming that there are only 9 long busbars you would only need 8 resistors to controll all 38 drawbars. Did I make myself clear ? I bigger schematic would help, but I don't know if I find some time. Bye the way, making it digital with a matrix would be cool, but in my opinion, it's allready done. Best andreas
  11. I really like it the way clavia did it with the nord. This kind of display seems to be very obvious and eays to handle. It like the "displaying device" to big. A small LCD or the 10x25mm LEDs are too small for me. 7X60mm might be enough. Honestly speaken, I don't know what to do now as I know that displaying drawbar settings after a preset change is not possible. The LEDs are a desireable thing to have. It have to think about it all. Best andreas
  12. @Hermes: "Thus I think that a full B4 control device is possible with only one core!! " Yep, needs some coding though. You have to add 64 analog inputs to MIDIO128. @Hermes: "I think you don' t need 58 digital inputs. If you look at the B4 midi implementaion chart (if one does not have it I ll be glad to send it via e-mail), only 6 of the controls require a "push button". That's true aswell. But there is one problem: chorus vibrato selector in the keyboard view. This switch is not listed in the midi implementaion chart. But it could be recoded using an analog 6 position switch and defining the two midicontroller (vibrato mix and depth) to each position. But this switch must be hooked to 6 digital inputs on order to add this "second output" (2nd midicontroller). For example C1 woul be 64 (mix) and 32 (depth), V3 would be 127 (mix) and 96 (depth). I would like to have this switch (and I think oldmacman aswell) to be as close B3 as it's possible to be. Coding will be needed aswell. @LEDs: I think I have bad news. I don't think that Hermes is describing a problem, but I didn't check it though. But what I found out is that B4 doesn't send controller data when a preset key is pressed. It only sends program change. And therefore it is not possible to indicate a drawbar setting called by preset changes. :'( And without this: I don't need LEDs. If the LEDs are only able to indicate the real drawbar setting (which I see anyway on my organ) I don't think why we should keep them. Disappointed I' m going to bed and whimper for a little while ;) andreas
  13. Dimitirs' suggestion is good and easy to do. If the length of the cable from core to bass pedal dosn't get too long (sub-d-25 pins cable could be used) it might work out. If it doesn't, never mind. It wouldn't kill your budget to use 3 core for the project (one additional for the pedal bass). But we don't need to work further on because (as far as I understood the MB64) everything is already prepared and has only to be configured with "serge's editor". Same with MIDIO128 for all of us who like to have keyboards. Only the LED-thing has to be coded. >:( Best andreas
  14. @Jim:"How about this idea? As Dimitris suggests, all B4 controls, other than manual keyboard scanning and LED drawbar indicators are handled in the first core. There should be enough digital inputs left (Dimitris, is this correct?) in MB64 to encode the 25 pedals." Nope, that doesn't work out. We need 58 switches for the console keys including presets. MB64 supports only 64 switches. But we need 83 for adding pedal switches to the function switches. But we could use analog inputs for Bank Select and Precussion Harmonic Select (e.g. analog pot. rather than switch input). That would save 19 switches and it would work. " Andreas, at current exchange rates, Petkov's PCB costs $190 US plus shipping. I'll stick with SmashTV's prices and far cheaper shipping... Also, I think with all of us working together, we'll get a better product. " I fully agree with you. While working all togeher we can develop a more powerful circuit than JDPedkov's. Later more from me andreas
  15. Now the discussion is going on. Let me see. First of all. @Jim: "As far as I know, B4 does not report back to the controller the position of the drawbars for their internal presets." Fortunately you're wrong. As I know from the Keyboards forum (german keyboards magazine) and just tested myself (I hooked the B4 to a MIDI monitor of my MIDITEMP PM-88E (a midimerger and midimatrix)) the B4 reports every MIDI-event to the MIDI-Out of your soundcard (which can be connected to the In-Port of the Core) and therefore it is possible to let N.I. B4 controll the LEDs. @Dimitris: With your MB64 beeing ready you might be done. All you wanted were those drawbars, switches and pots. You only have to configure your box and your done. Or am I wrong. Flash the MB64 software to your core and link the events to your input devices with serge's editor and go B4ing. @oldmacman: first of all welcome to the project. Your right, it's only an organ, but I made some expierence with a Hammond XB-2 (digital clone) in a rock cover band. In a band you often have thousands of sounds that are linked to special songs or even certain parts of songs. Using the presets gives you no controll of your settings (no display except the screen). the XB-2 had a small display indicating your drawbar settings after using a preset key. that was crappy, because it was a little bit tiney and you had no idea if you have choosen the right presets. With LEDs indicating your settings you "see what you're getting/hearing". If I wouldn't need the LEDs - to be honest- I think I would go and buy JD Pedkov's circuit: http://www.geocities.com/JDPetkov/Hardware/B4ce/B4ce.htm That would save time (=money) (I know you guys living in the U.S. wouldn't think of it because of the shipping costs). @all: I think the project should be organized this way: Core 1: handling the upper manual and everything else besides lower manual and pedal clavier That makes 119 switches, 25 analog inputs (db and swell pedal) and 21 digital inputs (question is still: do we need encoders. I'm not shure. Maybe pots are enough. Using pots would simplify the amplication, I would say.) Plus the LED (in my opinion/case). As I mentioned before we just talking about all the things to add for programming. Oldmacman, in case you don't like the LEDs (it's also a matter of money, LEDs are expensive and I have no idea how to integrate them to the cabinet) leave them and the DOUT-PCBs out. And one core is able to do it (see MIOS specs). Core 2: based on MIDIO128 handling lower manual and pedal board It's getting late. Hope to read from you soon. Best andreas
  16. Thanks for the compliment regarding my english. I really appreciate it. :-) "I'll answer your message in more detail later tonight. I may still toy with the idea of the motorfaders later but not for MIDIBoxB4. For one thing, 24 drawbars would require a minimum of three cores. " You mean 3 cores are needed if motor fader are used, right ? That is true. @LEDs: I don't need LED rings for the encoders either. A LCD displaying drawbarsettings will be fine aswell, but I'd like to have those LEDs cause I'm planning to use the MidiBoxB4 on stage and I'd like to "see what I get". :) @one core for 2nd keyboard and pedal: I searched the archiv and found the old post (it was in the german section). "Spanky" was asking about the max cable length between core and devices like switches or pots etc. Thorsten said everything longer 1m (3 feet) might get critical. "Spanky" tried it out with a cable of 3 meter (10 feet) (only switches were connected) and it worked well, so it looks like this problem is solved too. Since some time I'm thinking of adding a second db set for the upper manual (like the big Hammonds have) with a button (not one of the preset keys, an additional key) to switch between the two sets. Programming all the stuff in MIOS could become a problem. But I think if we're all working together it shoulnd't be a problem at all. Just in case we're stuck, I know a good forum to post our problems ;) Take care andreas
  17. Hi folks. So the project MidiBoxB4 is getting started ? @Jim: I would skip the idea of using motor faders. Reason: You would have to sync the movement of the motor fader to the movement of the drawbar (db): You have 128 steps for one controller. if the db is moved for one position it means an increasement of the midi controller value of 16 (decimal). With the fader moving for an midi value increment of 16 this length must be fitting to your db. Might be a difficult thing to do. I will use LEDs indicating db position instead. The same way as the guys from Clavia used the LEDs on the Clavia Nord Electro: Take a look. http://www.clavia.se/pictures/nordelectro/NE2drawabarsLarge.jpg But I need some more LEDs. ;) 24 x 8 LEDs for the db 4 LEDs for Drive , Percussion, 2x Vibrato 6 LEDs for Chorus Vibrato Selector 10 LEDs for Bank Select Indication 9 LEDs for Harmonic Selector 24 LEDs for Preset Selection 3 LEDs as Leslie speed indication That makes 248 LEDs. ;D Just timemultiplex them and everything will be fine. Encoders for the other features would be fine. But I think that I don't need them. I think I only need the drive section and the Vibrato Selection to change live on the fly. All other features of the B4 will be saved in presets. But that doesn't mean we should skip the code for all the others features: I would suggest we code an full featured implementation of the B4 and while building your box leave out all the things you don't need. Feature list: 61 switches for upper keyboard 61 switches for lower keyboard 25 switches for pedal 24 switches for Preset Keys 6 switches for Drive, Percussion, 2x Vibrato, Rotator, Velocity (I think we could just skip the last 2 switches I won't turn the Rotator Off or the Veloctiy On, but who knows) 10 position switch for Bank Select 9 Position switch for Harmonic Select (could be solved as 25th drawbar instead, what do you think?) 6 position switch for Chorus Vibrato Selector (Keyboard View) 24 analog inputs for the db 2 Encoders for Percussion volume and decay 2 Encoders for Vibrato mix and depth 1 Encoders for keyboard click 4 Encoders for drive section 8 Encoders for rotor section 4 Encoders for microphone section 1 analog input (volume pedal) for swell (the length of the connection calbe might become a problem as T.K. mentioned in one thread that they shoulln't get too long) 3 position switch for the Halfmoon Leslie Yes, I would like to have a 3 position switch in order to add something the guys from N.I. didn't think of: Leslie Brake. This can be achieved by setting both rotor slow controller values to zero. Shouldn't be a problem at all. So we need 205 switches (digital inputs) 25 analog inputs and 21 digital inputs for the encoders. That could ask too much of one single core, what do you think? ;) Thus, 248 digital outputs for the LEDs. (Which could archieved by 4 multiplexed DOUT Modules Ah, to add just another thing. It could be possible to indicate midi value of the encoders with LED rings ass well. I don't need it. Whats up with you, guys ? So. Writing that all took a lot of time (especially when you're not a native english speaker/writer). Hope to read from you soon). Best andreas
  18. I have sent you a private message. Just in case it is stuck somewhere in the middle: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=16219&item=3717302671&rd=1 best borntob4 By the way: I have ordered a 10 LED bar graph made by Kingbright but they are too tiney for my project. I need something more visuable but the 20 LED bar graph are too expensive (in my opinion)
  19. Ich bin zwar auch noch neu hier, aber ein paar Deiner Fragen kann ich dann doch beantworten: Stell Dir die MB64 wie einen Computer vor (den das ist es auch, nur ne Nummer kleiner) Das Core-Modul (Hauptplatine) ist das Mainboard, da sitzt der PIC (der Kopf der Bande) drauf, Du hast Anschlussmöglichkeiten für ein Netzteil, ein Display, MIDI-Buchsen, Bank-Stick sowie für die anderen Module (AIN, DIN, DOUT etc.). Das AIN-Modul brauchst Du, um analoge Steuerelemente (Fader, Potentiometer) an den Core anzuschließen. Über das DIN-Modul schließt man digitale Steuerelemente (Buttons, Endlosdrehregler, etc.) an den Core an. Über das DOUT-Modul kann man sich Controller-Werte der einzelnen Regler durch die Dioden anzeigen lassen oder andere digitale Schaltungen damit steuern. Z.B Du hast einen Softsynth der über Midi-Out bei Programmwechsel die neuen Offset-Werte der einzelnen Knöpfe sendet (CutOFF bei Synth xy bei Preset z ein MIDI-Wert 25, dann wird Dir bei entsprechender Programmierung dieser Wert nach dem Preset-Wechsel über die Dioden angezeigt).Das war ein allgemeines Beispiel und ist bei der MB64 nicht implementiert. Da hast Du "nur" 64 LED die Du beliebig "programmieren" kannst. Bei der MB64 zeigen die LED an, ob der Button grückt ist oder nicht. Wenn Du ein Display anschließen willst dann brauchst Du das LCD Module. Also für die hier "Potis,Fader,Taster, LED´s,Display, " erwähnten Bauelemente anschließen willst brauchst Du neben dem Core, 2xAIN (für 64 Fader oder Potis), 2 DIN für 64 Buttons und 2 DOUT für 64 LEDs. Guckst Du hier: http://www.ucapps.de/mbhp/mbhp_midibox64.gif Ich sehe gerade, das für das MB64 jede Menge Hilfe wie das Tutorial auf der Page stehen, ich denke Du solltest Dein Englisch aufpolieren und Dich da mal durchkämpfen. http://www.ucapps.de/midibox64_tutorial_en.html @Platinen ätzen lassen www.mikes-elektronikseite.de. @MB64E E steht für Encoder = Endlosdrehregler, das heiß Du hast nicht wie bei einem Poti einen Links- und eine Rechtsanschlag. Je nach zu steuernder Software ganz nett zu haben. Viel Spass und mein tipp Englisch-Deutsch-Lexikon Gruß borntob4
  20. if I would life in the US, I would buy something like that http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=3711360695&category=16219 and be the happiest man in the world. but these keyboards are to heavy=expensive to ship to Europe. what a pitty. But maybee it is interesting for you, Jim ? You get a real warerfall keyboard with the big set of dbs. Looks cool. good night it's getting late borntob4
  21. " What's needed is MidiBoxB4..." That's for sure. Concerning Fader or Drawbars I found a good solution. I want my midibox only to control NI B4, so I don't need faders. They are expensive and difficult to attach with something similiar like a drawbar. What I did, was pretty cheap and THE REAL THING: Buy used drawbars at ebay instead. There a some dealers who sell old drawbars from M100 or M3-organs. for example: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=2570624578&category=16219 search for hammond and drawbar, but keep away from the big sets of B3, C3 and A100 with the 4 sets with 9 drawbars each and 2 for the bass. They will get pretty expensive cause they are rare and an often needed spare parts. You need 2 of them to get all 24 bars. I spent 10 $ for each of them. Clean them up a little bit (especially the busbars) and reorganize them to have 2 9 drawbars sets side by side and the 6 for the bass separatly. Then you have to solder 8 resistors to the 9 bars (one 1.2K ohm resistor soldered to 2 busbars) and hook Vss to the last and Vdd to the first and bar and use the drawbars with the AIN-Module. By using a drawbar you will increase the value of the drawbars resistor by 1.2k ohm and the pic will increase the matching Continious Controller by 16, that is one position of the drawbar of the B4 further out or in. Did I make myself clear. I will look for a explaination concerning the resistor-thing. When the drawbar (db) is in Position 0 you have 0 ohm, if the db is in position 9, you have 9.6k ohm. And the PIC of your MIDIbox will "translate" that to a midicommand. Maybee I'l find someone with a digital camera, so that I can make some pictures of the modification. I will figure that out. Best borntob4
  22. Motorized ? That would be awesome, but I'm not planning to do so. Sounds a little bit to complicated, especially with getting a good mechanic working on the real drawbars. No, I think with the LED bargraphs displaying my drawbar settings I don't need motorized drawbars. I would leave out the LED in that case. Best borntob4
  23. Sounds good, but I will use real Drawbars with the AIN instead. Have all 24 of them already prepared. Bought them at ebay.com. But I have to fix the "programming problem" with MIOS first. What device are you planing to control? Native Instruments' B4 aswell ? best borntob
  24. You've got me. I want to build an userinterface for Native Instruments B4. But I like to see the current drawbar setting on the keyboard (similiar to Nord Electro). Don't want to move my head in order to look at the screen. I'm a little bit lazy, you know ;) Best and thanks for your help borntob4
  25. Hi folks. I'm searching for a 8 LED segment bargraph with 8 separated LEDs in one housing (with all LEDs on 8 seprate LED should be recognized). Does anyone have a suggestion concerning dealers or manufacturers. Measurements similiar to 0.2X2.4 inches or 5x60mm Thanks a lot borntob4
