  1. I don't own a RD-8, but i'm interested to buy one at a later point. On gearslutz.com there is a thread about modifications for the RD-8 and i just asked Maffez, who is the person that comes every day with new ways to mod the RD-8 around the corner. https://www.gearslutz.com/board/modular-mania-all-things-eurorack-and-modular-synths-effects/1278739-behringer-rd-8-diy-modifications.html The RD-8 seems to become a great success for Behringer. Seems they can not produce them as fast as they sell them. The first batch was completly sold out, after a couple of days. But with a price ta
  2. Just want to share, that the new Behringer RD-8 drummachine is using a STM32F405. Maybe MIOS is an option as an alternative Firmware for those of you who own one.
  3. @Psykhaze What happened to this project? Was it abandoned?
  4. I tried to create something with the SRs directly on the board - there is really little space between all the switches. :D With a classic Diode Button matrix it would make much more sense and i could choose between much more available switches/button caps. Not to say, that spst switches might be cheaper and easier to wire. It would also make much sense, to change the wiring of switches and encoders to different SR and SR pins, to bring the SRs closer to where they needed and to avoid a spidernet going from everywhere to everywhere across the board. I made a new schematic utilizing a
  5. Yeah, in case i would do that, i would only use SO-16 packages, the DIL-16 used on the DINX4/DOUTX4 are way to big. Using smd resistors would be mandatory too, to be able to fit that to the board. Do you think theres someone who want to build one of these boards too? If anybody want to join in, just write a message here. Unfortunately my programming skills are near zero,but in case someone could help out and adapt the code for more inputs, i could change the whole approach with spst switches instead of the dpdt ones and some additional changes to the button layout. I would just
  6. Ups yes, that was a typo, i meant Vs, i will fix it in the original post. It's not a bad idea, to include the DIN/DOUT directly to the frontpanel pcb. But on the other hand, i have DINX4/DOUTX4 boards still in use with the actual setup of my MIDIbox FM, so no need to build it again.
  7. The Pin Headers will connect to a DINX4 and a DOUTX4. No need to add even more resistors. Its basicly the standard wiring for the extended Frontpanel. http://www.ucapps.de/midibox_fm/mbfm_din_default.pdf http://www.ucapps.de/midibox_fm/mbfm_din_default.pdf Only difference is that i used 24 dpdt switches for the 4x6 matrix. To be true, its not really a button matrix. In the original design every row has a switch and every column too. My dpdt switches will work as if you press 2 buttons, (a row and a cloumn button) on the original design. So if i press any of the button in
  8. I have a question regarding Eeschema (i use KiCad). I wired all Vs connections to the bus, is that ok or should i use ground symbols instead of connecting Vc to the bus? I ask, because i have no clue, if Kicad might build it's ratnest differently, when it has to wire a ground line, or maybe theres any other reason i didn't tink of, not to wire Vc to a bus.

  9. The DPDT momentary switches i will use, are much taller than most tactile switches and i realised, that there might be a problem with the height, because the rotary encoders are too short to have switches and encoders on one board. It seems i have to make 2 small extra pcbs for the encoders and put them on shorter spacers, to get them closer to the prontplate. This sucks a little bit, because it will need more space for additional screws and some additional pinheaders.
  10. Might not be the best solution to push the LEDs into the board with force, because they are mounted on a pcb and the resulting force will bend their legs. Good hint, to use a white Oled with a transparent red acrylic window! It's a MIOS8 core on a PIC18F4585. Maybe @TK. can tell us if it might work? @latigid on When you tinkered around with these OLEDs, was it possible to use them just as a pure hardware replacement instead of a HD44780 LCD display or did you had to change something in the code to make them work on your core32? My english is not the best, , so wha
  11. I want to use rectangular 2mm x 5mm LEDs, because they look so much cooler than the regular round ones. But i realized quickly, that traditional CNC milling will always make rounded edges on the cutouts in the panel, with the size of the diameter of the milling tool. This will make it hard to fit a rectangular LED into the cutout without adding additional gap width to the cutout or sanding the edges of the LED. I will have to checkout if laser cutting, punching or something else might be the solution for my problem. Any hints from the more experienced case builders are highly welcomed.
  12. Hi folks. I've build a MIDIbox FM years ago and had a lot of fun with it in the last years, but i've never taken the time to design the beautiful case that this synth deserves. It might have to do with the fact, that building something really cool would make the sausage casing more expensive than the sausage. However, in the last days i came to the conclusion, that now it's the time to build something nice and i started with it. Unfortunately i never made a professional designed PCB by myself, but this time the handwired strip boards i used with my projects in the past wont do th
  13. Hi all and a happy new year. I'm just courious, because the basic version still sounds quite nice and i would love to see a vst version with tweakable knobs and buttons, but - is this project dead or just on the bottom of your priority list Thorsten? Best Regards, Thomasch
  14. Or check this - 5pol din for 0,35€/piece. https://www.musikding.de/DIN-Buchse-5-polig-Print EDIT: Just saw, they are out of stock. maybe it makes sense to email the shop owner.
  15. Hallo Rolf. Mir gefällt dein Synth recht gut. Schade, daß er nur monophon spielbar ist. Soundmäßig deckt dein Synth nen Haufen Sounds ab, daß man sie nur monophon nutzen kann schränkt den Nutzen allerdings grob auf Bass- und Lead Sounds ein. (Es mag Ausnahmen geben) Hast du schon Pläne für einen DeGenerator 2 mit polyphoner/multitimbraler Soundengine und Einzelausgängen?
