  1. Hi Zener, well i don't use any virtual instruments so the short answer is : no. But, i don't see why it couldn't be used for that too if needed. Thomas
  2. HI! It's time for a quick update! I'm in the process of building the console frame right now. Mostly because 90% of the pcb assemblies are done and because i need a way to wire everything together without becoming too messy (I fried 2 stm32 Discovery so far due to bad wiring). So I assembled a model today and it came out great! I'm really pleased with the dimensions and the sloping of the frame right now, but some dimensions are too tight to fit everything together, so i'll have to redo everything (thankfully it's made out of scrap wood). To give an idea o
  3. Well, there's nothing in the doc about using ASCII code with MidiBox NG, so i'm not sure you can do that. Unfortunately my STM32F4 board fried last time i plugged it (messy wiring) so i can't try anything right now. Sorry I couldn't help, Thomas
  4. Hi, I don't think the built in fonts have special characters available. I remember reading a thread about creating you're own custom fonts, but it involved recompiling the MB_NG firmware. Search the forum, you light be lucky Thomas Edit: I found it! it was in the wiki page: http://wiki.midibox.org/doku.php?id=how_to_create_custom_glcd_fonts_icons_bars_for_midibox_ng
  5. Hi, Yes, you can chain up to 4 of these boards together. You need to change the #id of at least one of the controllers to be able to use them with MIOS studio. I've not done it myself everything is ecplained in this thread: You should read the whole thread, it's full of good info on how to setup the board properly. Are you using a core module to interface with the MF_NG? Or do you want to connect them directly to the computer? Cheers, Thomas
  6. HI Zeke and thanks for the advice! I'm building a DAW controller, basically i'll emulate 3 Mackie Control Units plus a "generic remote" to control Nuendo. In the end, i hope to get 25 faders plus a bunch of stuff (including a touch screen with a lemur patch). I reported my progress in this thread (not updated very often though) : Right now i have only fader attached to the board. The wiring with this board is a bit of a mess so i'm currently making a new pcb with one connector for each fader to keep things tidy. I'll definitely try with 8 faders connected, but in the near futur
  7. No worrys, as I said, i think i will settle for this solution for now. I'd like to have a working build before end of the year and improve from there. If I remember well, you're problem with PWM was related to EMI leaking into the analog circuitry, not the actual physical noise of the fader. Am I right? You're right, the PIC used on MF_NG won't go higher in frequency, But if need be, i'm not afraid to port the code to a more capable micro... (as long as i have a working controller, i have all the time in the world to make it better... ) I never looked inside a D-command, bu
  8. You need to download an old version of MPLAB to use a pickit 2. A quick search in google tells me MPLAB IDE v8.92 is the latest version with pickit2 support. all older versions of mplab are available on microchip webpage: https://www.microchip.com/development-tools/pic-and-dspic-downloads-archive Or you can buy pickit3 or 4 and use MPLAB X Cheers, Thomas
  9. Hi Zam, After reading ths whole topic again last week-end, I tried to lower the voltage. With Vm down to about 4V, i was able to get rid of most of the mechanical noise, but now the faders are a bit sluggish (actually, there's only one fader wired to the board right now). The PWM might be the problem, I know you went another route for your analog automation system (I followed the story since the beginning on gdyi). Do you think we could get rid of that noise using a higher PWM frequency? Or is it necessary to drive faders with DACs instead? There must be a way
  10. There is, but not in the more usual form of an analog signal. It acts as an encoder, sending pulses when you move the fader. Yes, that's how these faders are used A DIN is a module connected to a core module. It's used to interact with pushbuttons / switches and encoders. Look at ucapps.de, evrything is explained there. Yes I'm afraid it would not be an easy setup. But... you would learn a LOT of things in the way !!!! To me at least, that's where the fun is. I'm currently building my own DAW controller, and i know more things than befor
  11. According to datasheet, it's rather a 512 steps/turn encoder. ref is IE2 512 250 (i read wrong in the previous post). Assuming the datasheet didn't change in more than 20 years (which is possible with these kind of product). Then you might be able to drive them with MidiBox NG, but you would need to modify the code i guess. My knowledge stops at this point though, I'm not comfortable enough with C / ASM... The manufacturer of these motors also provides some control boards for them. Might be worth a look, but most of them use CAN or RS232 buses... so no direct compatibility wit
  12. Well, that's also a possibility. Now that you mention it, the second ref on the motor might refer to this https://www.faulhaber.com/fileadmin/Import/Media/FR_IE2-1024_DFF.pdf Or rather an discontinued version of it? IE2 512 256 would then mean 512 or 256 impulse per turn. In this case, you can't use MB_MF_NG to control them. Cheers, Thomas
  13. Hi, This is all good information, we're closing in... So 1 and 2 should be the DC motor as I expected. Now the four others must be 100%V, 0%V, Wiper, and Touch sense. In that order IF P&G kept the same when changing design. (which they seem to be doing) The other measurement don't make much sense though, maybe an error when measuring? 800k is really high for any kind of fader. measure between each pin and the lever. One should be a short and the others should be open. That would indentifiy the Touch Sense pin. This should left you with the potentiometer pins.
  14. Yes they're probably older versions, but as I said, i have another old version of P&G motor fader here and the one I have here are already called PGFM3200 (not PGF3200). And they comply to the last datasheet even if they have a different mecanical arrangment: Waiting for more info on that... Cheers, Thomas
  15. Hi, these look weird. P&G motorfaders should be PGFM3200. And the motor should be top or bottom. Maybe a custom job for a manufacturer? Do you have photos of the whole assembly? Where do they come from? Which console? It could be an older model, but it seems unlikely to me. I have a quite old P&G fader here, and it's already named PGFM3200 and has the same color coding than the more recent ones. Those motors look like 6v DC motors so you should be able to drive them with MB_MF_NG module https://www.faulhaber.com/fr/produits/series/2224sr/ Can you
