the whole midibox hardware platform is modular.... they are all seperat modules that can be chained togehter with standart crimpable ribbon cables. if you speak of modular you might mean the Case - the housing - the 19" Rack or so > i suggest a system that has a rail for free movable screw nuts, so you can replace frontpanel and backpanel parts when you update the system.... the wireing internal i would make with ribbon cables instead of "power rails" ---- e.g.: http://www.schneidersladen.de/de/tiptop-audio-z-ears.html http://www.schneidersladen.de/de/sb-rail-1m-ohne-kante.html http://www.schneidersladen.de/de/sb-rail-19-mit-kante.html i dont have tried this products... i only say it is a good idea

Bei der Bildergallery gibts zwar das miniaturbild (übersicht/thumbnail), aber wennst dann auf eins drauf drückst sehe ich kein Bild.

bei mia föan´s ah ;) < Edit bei (neuen?) Posts sieht mas.

first thankz for replay... 1. Make the Organ a midi-soundmodule - means: play sounds via Midi * i dont want to remote the Soundregisters - i will do that orginal on the device * that means i Remove all "Gate"-Cables and rewire it via Digital-out-shift-registers * integrate my trigger-melody software, and a midilooper for 1 - no problem, except the Ground thing > 0V of the Shiftregister is not Ground enough...may it be the impedance i dont know. ;) i played around with potentiometers, and i got a impedance that worked, but with that the "high"-state is not high enough ... maybe the ULM will do the job! 2. Recable the orginal Keyboard with 3xDINX4Modules.... how ever in the meantime i got a "CRUMAR 198 Sustain" and this device needs +15V @ Gate Input.... a BC549 do the job for organ sounds...a extra10uF and 1K resistors gates the Fade-out sounds (Piano sounds) the crumar sounds better and it costs me nothing except petrol... but its good that you write about the ULM.

na... i have tried that already... i inverted my code ----- but then all Voices where sounding a bit (@but all Voices get 5V > means "please no sound"), also the Voice Chip was getting warmer.... i thenplayed arround out with a 4MOhm Poti a resistance in series with a DOUT-pin, and find that a 1Mohm Resistor kills the sounding, but when i then activate a voice (means deactavate a DOUT-Pin > Midibox = 0V) the Played Volume/Gain is a about 1/4 of the loudness - when i connect it to ground directly... maybe i need some circuit around the HC595?

I am trying to midifcate my electronic organ. The Organ itself gives the loudest sound when feeding it with Keypresses on "Groundlevel". But a HC595 gives me +5V. - How to manage that. Any idea?

i am intresteted in a button bulk (austria > up to now EU)... since i need buttons for 2 PCBs... and a few more for other projects...

for me the case could wait, the soldering will take a while anyway...asambling later. it would be tragic if the whole thing did not get reality... its time for a new way of making music :phone: ... a step forward to be complete...ya i know thats impossible. do you have Part (type)-list for this thing? (how many shift registers, size of smd leds and so on, numbers silicon button-matrices, fader)'

they are the same.

just to be shure: that sd-card slot > you use it on the stm32f4 core-pcb? because the sd-slot that i get from mouser is a 3M ND04620A which (also) fits on the stm32F4 core. well then - send me a pm with your adress!
