CRUMAR 198 (1976) i love that device... i did not learned keyboarding... but with that thing i start it by by doing... i was always a step-setter...so excuse that i dont find "the right notes" > newbee well i have great planes with it. built in my triggermatrix, which is some kind of play help, rythm automatic and so on... better you watch my video to understand.... @ the moment only the upper manual is midified with a Core32, and my program "triggermatrix" on it... the basic idea is: Connect a drummer, or rythm machine via midi to it, the drum trigger -"re-Trigger" the Key-notes which i press, i can deside via a Matrix which drumtrigger triggers which manual... also there are "song parts" to switch between Trigger-Presets, and Roll-Prests...also the gate length can be changed, and random trigger killer is also integrated... and much more... how ever , i want leds duo-colour-leds over each Key to show me the last Keys i have pressed... because, when i press a chord-set, which get repeated via the drum trigger...no it sounds... and sounds... meanwhile i go to the lower manual and play, or do bass pedals, or do reverb or drumsequencing or drumsounding... after a few seconds i have vorgotten which dam chords i pressed on the upper manual... so this is a must, i know how to do that... soldering a few weeks of course... also the leds will show me fittings notes in the circle fifth... and of course the pressed keys are indicated on the lower manual to over all octaves, in order to learn how to play, while i play... a circle of fifth note corection, which shifts the ohter manual when playing the other, and then falling back again...and also automaticly bass folwing is plan... but up to now i am very happy with this upper manual and the midicontroll via bcr2000. i think i will make the UI via designed PCB which i will order then, because i need 2time the same UI i think it is very clever to make that right...... i also want to replace those Registers via Potentiometers aka "Zugriegel"... also i want to add a triggered Lopassfilter for each manual... and much more of course... but enough, now Videos for ears and eyes, and pictures for your eyes and brain - have fun! well i have. Swell pedal via foto resistor and a 24V light pulb! old psu amp and Loudspeaker, i romed amp and Louspeaker and replaced the power supply the new one a "bit oversized"... but that parts i have lying around for 15years!!! (never realized amp project...) spring reverb tank and foot pedals spring reverb magnetic driver removed rythm "engine" "walz tango march, slow rong swing rock genuine, bossa nova, bass-auto and chords will be replaced with a midibox core32 my program "triggermatrix" and real Drummachine!!! in order for that you can cut the whole cable-tree... but then you have to solder the orange and one of the dark green cables 2gether, in order to get the lowest octave from the lower manual to work..... there are 2 dark green cables, you have to take the one that goes to the lower manual to the manual - key spirals.. dout modules 5V and level shifter 15V (BC549)...there are 88 outputs for 44 keys, because, 44 are organ, and 44 are "piano" envelope types...while the piano swell down with the 100uF caps, the organs will be hold... the selfe eteched din modules. din wired, core mounted the shematic to midified that thing: THE 220 Ohm must be replaced via an 10-22K, and the 1K is also not right... i then used a 2K2... but that Transistor get warm and all 44 of them take a current from 0,5A!!!... the powersuplly was not strong enough for that (with the CORE and the LCD in addation...)... but i think that was of cours of dry electroly caps... burned finger caps? no more! video with jamsession is on upload...

yes it shares the same ground anyway i realized via BC549 Transistors. DOUT-PIN>10K>Base +15V>1K>Collector Ground>Emitter the whole thing x44 = 500mA... seems the 1K is a bit low ;).... 500mA is not much but.... enough to screw my Powersupply with dry elkos.....

with midi you dont have to have chains... of course you can make chains....>>>> just build more midi IOs on your MAIN-Box >>> http://ucapps.de/mbhp_midi_io.html....

i also would do it via Midi --- or better OSC or Networkcables, to reduce midi cables... but osc on midibox you have to understand first...

256 individual inputs, of course but, you can use matrixes and scan that via software, and so you get more that 256 individual inputs.... softwareside i dont have done this... but others have done it... (search for BLM) 256 individual outputs, also can be arranged to matrixes... (also BLM, or SID LED-Matrix, Triggermatrix...), the size of it depends on the Shiftregister (HC595) and its maximal current, but there also alternatives with more current, or transistor circuits to drive bigger matrixes... networkcable - yes - make sure it has pair shields make sure that shields are connected to ground on one side of the cable The DIN and DOUT Modules (digital in, digital out) has to be connected via Connector Socket J1 to the J8/J9 Sockt on the Core Module J1 has 5 Contacts: Put following cables in a pair: VS, VD SI SC, RC To get more Amperes over the cable make it like this: VS VD SI SC,RC I dont know is it clever to put SC and RC in a own shield (pair?): VS, VD SI SC RC tips... well read that: Midibox NG for programming: I did not have to do with the Midibox NG... i took a MIOS32 skeleton and programmed my own concept. and it took a while to understand different things, and many things i dont understand up to now (like OSC and Ethernet) best you use Midibox NG... they have thougt about how a Midicontroller should work. when you want to use your concept of only core, and want to add more modules after time or on a running system, you have to add an "OFFSET to your shiftregister pin-outs) ....for example: activate a LED on a new connected module: LEDs are connected to Shiftregisters mainly "HC595" this registers have 8 PINs, you want to activate LED0 now, LED0 is connected to Shiftregister pin 0, All Shiftregisters are in an chain >>> all registers are connected serial one after a nother...if you connect your EXTRA/Modular Midibox to your CORE/MAIN-Midibox - then the chain starts on the core modules, and goes thru all DOUT-Registers in the MAIN-Midibox, until it goes to a connector where you plug your EXTRA-Midibox... well lets say there are 4 Shiftregister in the Main Midibox, the EXTRA-Midibox now starts with the 5th Shiftregisters... a LED gets software side activated in a way like this (pin, pin_value), so the first pin of your EXTRA-Midibox is: 32 (the pins start by 0, and 4 Registers * 8 Pins = 32 32+0 =32) so the point is, you have to program a offset to this >>> pin+Offset=real pin >>> the offset could be set by a "Connector switch", a Switch which is Connected to a DIN-PIN, if this DIN-Pin is acticated the Software set a PIN-Offset .... like an DEVICE ID that are my thougts... a LED on a specific pin (maybe pin 0) on a shiftregister (a shiftregister has 8 pin

checked the datasheet... i tryed 1K Resistors to 15V on the output but with that i got in "low Mode" 1,5V.... high 15V.... but i need 0V @low? a little bit info pleas- thankz

no i would go for twisted pair - shieldet in pairs, or better individually. daisy chain... yes possible and necessery! all the used shiftregisters has to be connected one after a nother --- and if change the connecting you have to change your Coder!!!! (pin) it depends on your code - (memory on ic) and on the hardware: 256 buttons or 128encoders.... the same for DOUts but 16Led rings needs 24 dout pins http://www.ucapps.de/mbhp/mbhp_dout_8x16leds.pdf i dont made ledrings up to now...so someone other can help!

With one Brain hmm i see: 1. connect the boxes via 5pole shieldet cables (used for Shiftregister and Current) > CAT-Cable, and really keep them short! or 2. Use LINE-Driver - Boards to expand the cable length http://ucapps.de/mbhp_line_driver.html

a uln2803 for S-Trig... yes that makes the job any idea for a transistor array for a V-Trig 15V? for my other organ? @the moment i use BC337...by the way the Caps make the Piano-Trggers, while the standart output of the BC337 make the Hold-Organ-Trigger
