  1. got mine! light and beauty! ...in my dreams a few weeks ago i saw a some mushrooms in the wood, suddenly i saw a 16x32 blm on a dirty wodden desk, the set arround was a dessert party place, but the blm was still playing... in this moment i saw a woman and i decided to follow her... thx
  2. für die dies verstehn...einfoch des o und das e gegen ein a austauschen >>> Österreich ;) das konzept hier nochmal erklärt.
  3. very cool idea...to get some main beat grid for fitting lyrics (e.g. Hip hop)
  4. 5x350x350mm=233USD...ok good price...wtf how? ok i know how china... yes start such a synth on this platform... because i dont know how to , but i like to watch and learn from... (grabbing the code) cheers. Edit: did you paid "zoll" (landed cost)??? evertime i order pcbs from smash tv (america) i pay "zoll" (to Austria) past week i paid for a 160$ order 40€ "zoll"
  5. 1st electronic labor jam made with some parts of an old SIEL-E-Organ > spring reverb/driver > amp > filters also a rose-crystal coil - transducer, which also act as a lopass filter when hold over a spring reverb... korg electribe rythm and mbase...straight outha my electronic labor 3rdRootsJam a midiboxified CRUMAR Model 198 e-organ triggerd with a kord electribe rythm... the program on it is the triggermatrix. straight outa my sun room, more info about that in this forum article: crumar-198-electrical-organ-midification-triggermatrix
  6. you see right, but, thats also for some play-automatic thing which pcb´s i already trashed. the bass working great with only the middle row switch parts... ya reichelt: http://www.reichelt.com/index.html?&ACTION=446&LA=446&SEARCH=jfet&OFFSET=16&SORT=artnr&SHOW=1 or english: http://www.reichelt.com/index.html?&ACTION=446&LA=446&SEARCH=jfet&OFFSET=16&SORT=artnr&SHOW=1 but 2n 2p jfet > like i said > i know nothing about fet-types - is there a nother word for that 4channel type you suggested? I am interested in this because up to now it seems to be the cheapest solution.
  7. yes i am sure... the other contacts are for rythm automatic, and autocord stuff... wich i completely replaced with my own things... @reed relais as describet here 1,54€x13= 20€ http://www.reichelt.com/SIL-7271-D-5V/3/index.html?&ACTION=3&LA=446&ARTICLE=27672&artnr=SIL+7271-D+5V&SEARCH=sil7271 max4066 =15€ 4N25 0,25€*13=3,25€ http://www.reichelt.com/index.html?&ACTION=446&LA=446 but i am doing hard to find a 2n 2p fet, and i dont have any expirence downside pipolar transistors
  8. does it work? depends on price,16 up to 64
  9. hi! Digital DC & Tranisostors: is there a change to clean that DC with a Capacitor? Transistor would be the cheapest soluditon it is not necessery to be DPDT.... it is also possible to hear all notes together (i soldered 2 "Notes" together and there is no problem), i could do that software side anyway (but i dont need it) 6VAC peak...: @ the end of the day i need 0.26V to drive Bass-Post-Amp, so it want peak. as far as i know from transistors is: that there is a BASE-Collector Voltage, even if there is no Voltage on the Emitter - so have a LEAK, i measured 20mv, which i alreaedy said - is hearable as silent bass (since the base is the bass-signal).... i was thinking to make a noise-gate circuit after summing all Bass-notes...but then i thougt when i summing all 13 Bass-Notes, with its 13 20mV leaks, it would be pretty loud, and maybe then i have to set the threshold to high...and also i will hear all notes together - of course the played note is louder then the other,there will be "hum" if i cant avoid the B-C-Leak. i searched for analog switch ic, and found this: MAX4066: http://www.mouser.at/ProductDetail/Maxim-Integrated/MAX4066CPD+/?qs=sGAEpiMZZMvbyeSUH4qH%2fNdIvyU6Oqzm http://www.mouser.com/ds/2/256/MAX4066-MAX4066A-72194.pdf ...i am looking for a lofi locost solution.... when i want it better i just connect my waldorf pulse via midi to the pedal. but 2.66€x5=14€... thats ok do you think the max4066 could do the job? optoisolators are to expensive (keep in mind there are x13notes)
  10. i need some audio-switching in my crumars 198 organ, the bass pedal is just a analog switching matrix, which decides which note will be played... to bad that all 13 notes via AUDIO are going to the pedal, not the other way around (not:pedal send gates to oscillator...this: frequencedivider sends audio signals to pedal) i want to controll the bass section via midi... or better said via a doutmodule > 5V > sound, 0V > no sound. so i need 13 Dout Pins = 2xHC595, done i dont want to use releais to swich all the 13 audio signals... i dont have a problem with distortion... ( i thought of Transistors???) i want that it is quiet when the 595 is LO. the Audio signals are coming from a frequenc devider IC that sends out 6V Sinus, the orginal shematic sends that signal thru a 100K resistor, and it ends with an voltage @ 265mV.... and the worst: the "orginal shematic" i buyd is not identical with the reality i have in front of me... i thought of using a bc547, in a shematic like in the sid module... by feeding the emitter with the 5V from the dout-pin,... when i now switch the DOUT off (lo) or clamp it to ground, i get a Base-Collector voltage by around 20mV, which is enough to be heard.......a resistor @ audio-out from that circuit end up by lowering the loudness in hi-state... a played around with potentiometers to set up the bc547...not worked @all, i think i have problem, which i cant solve alone > thanks
  11. crumar 198 bass section... there must be different 198ers out there because, my machine has a other circuit...
  12. with 32F4 you have to solder as well, there exist also (like on the LPC Board) a "Motherboard" > the CORE. the LPCore has 4 Midiconnections 2in/2out, on board, while 32F4 has none > where you have to built external Midi-IO-Boards....since for easier cable connections between the boxes you have to built external Midi-IO-Boards in any (your) way (LPC or 32F4) For me, i dont buy LPC Cores anymore... because i need the additional Performance of the 32F4 for my programms.... anyway in the past it was a compact solution, witht that Midi-IO-s onboard.
  13. 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...
  14. spring reverb "tank", with shock absorbing foods, mounting on the "ground" of the heavy organ, to keep it isolted from manual key presses and so on...
  15. spring reverb electromagnetic
  16. yessss I love it - a analog reverb > a spring reverb... i never had seen something like this... first see- first love... what genuis made shuch things - a ambassador of the the electro analog century... cool of course that the crumar 198 has a driver and a post amp for it...with the bought shematics i am able to boost the post amp... my plan is to feed the driver circuit with a dout-pin which will act as accent... with my trigger matrix i am then able to route drumtrigger impulses to boost the volumes rythmicly... independet from the organ sound rythmic sound structure which comes in...

    PSU-Shematics.JPG

    The orginal power supply... it breaks down by an load over 1,5A...but maybe only because of them dry electrolyt caps... remarkable, in the left button corner - there is the shematic of the swell Pedal (aka volume) directly bevore the main-out plug, there is photo-resistor which driven by an 24V Light bulk, the light shines thru a whole or better a stripe which get bigger when you press the pedal...> real analog!

    PSU-OLD.JPG

    old psu, and loudspeaker amp... i removed the amp and speaker, and replaced the powersupply by an RING-CORE-Transformator one

    PSU-NEW.JPG

    replace the bower supply... or better adapt it... the parts where from an amp project that i never startetd anyway (15 years ago...)
