  1. NRPN issues - can't go past NRPN #256

    yeah thanks this seems to make a lot of sense, will try first thing tomorrow. i also should have tried to go to nrpn values that would have used the next bit.

    so clean!

    yeah picture is too small i want some details of this beauty! great job! building a hardware controller for one specific plugin is very intriguing and reminds me of this guy, great projects: http://www.synth-project.de/diva.html
  4. NRPN issues - can't go past NRPN #256

    oh you mean in the NGC config? i will try that as soon as i am with the hardware again, thanks.
  5. NRPN issues - can't go past NRPN #256

    on the receiver side i am monitoring the midi incoming from the midibox with the axoxloti serial monitor, which shows the same value that mios studio shows sending. so, mios studio seems to display the "correct" values that are actually being sent. just CC99 only ranges from 0-1 instead 0-127.
  6. NRPN issues - can't go past NRPN #256

    i gguess worst case i can work around by sendin gthe first 256 on channel 1 and then a second set of 256 NRPNs on channel 2 would be enough for me. just have to decode back to the original numbering on the receiver side.
  7. hello friends, i have a problem with my rotary encoders sending several banks of midi NRPN data - i can't go past NRPN number 256! the second byte of the midi nrpn number message (ie. midi CC 99) midibox sends only goes from 0 to 1, as shown on the mios studio output monitor. it says in the manual that the nrpn number is also 14bit range as per the midi standard nrpn=<0..16383> Specifies the NRPN number (0..16383) for type=NRPN events is this a known issue? am i doing something wrong (presumably...) this is an EVENT ENC definition that shows: EVENT_ENC id= 55 hw_id=7 bank=3 type=nrpn nrpn=261 chn= 1 range= 4095:0 enc_speed_mode=fast:6 offset= 0 ports=10001000000010000000 lcd_pos=1:1:1 label="^std_enc" value= 0 so, this give me CC99 = 1 CC98 = 5, NRPN = 133 instead of CC99 = 2 cc98 = 5, NRPN = 261 that i wanted. only the first bit of CC99 seems to be changed, effectively giving me 8bit range.  
  8. double post soryy pls delete

    edit sorry for double post please delete
  9. Ok so here’s a summary: Production run arrived and is working perfectly fine. Looks amazing too. Breakable LED PCB with 4x32 ws2812 2020 LEDs, 3 pin connectors Encoder PCBs with 2x 74HC595 and 4 encoder slots Additional test points on the encoder board for 4-8 remaining 74HC595 channels, for use with additional buttons etc. 4 or 8 depends on whether you use encoder with ir without switches. Net price per set (1 LED PCB, one ENC PCB, you need to buy & solder encoders and connectors everything else is assembled) 22 EUR Add shipping cost to that. I am shipping from Europe. Within EU, around 4 EUR uninsured, 7 EUR insured. US shipping tbd. I could ship them from the US end of october. If you need a business invoice, add 19% VAT. I will reach out to everybody who showed interest. I have a small amount of extras so hit me up on this forum via DM or via mail rgbledring at gmail I’ll post some more pics and details on my experiences and mounting options asap. As I described in earlier posts, these are supposed to work with all major embedded platforms, specifically Arduino, axoloti and midibox. But you are only buying the hardware from me, no guarantees, no software support etc etc etc. The Encoder boards were originally designed for the midibox platform so they come with a 10pin IDC connector slot. I will provide pinout and schematics to buyers of course.
  10. The updated boards finally arrived! will do some tests over the weekend and report back next week!
  11. MidiBox DAW Controller

    Couple thoughts: great idea, i think it's quite feasible and will be worth the effort. will take longer and depending on your needs also not be cheaper than a commercial solution. all the buttons/pots/encoders in the world are no issue to connect obviously. i have some nice rotary encoders with fancy LED ringgs around them available if you want haha. one of the biggest issue i see with my limited knowledge is the DAW implementation. Does Nuendo allow to control the CURRENTLY SELECTED eq/dyn with a fixed CC or NRPN adress? or how are you thinking to realize the dynamic mapping? also sending out matching dynamic data from your DAW for your OLEDs, not sure if mackie control protocol supplies all this conveniently? oh also for that amount of OLEDs and input stuff you might need a couple more MCUs/core boards down the line i think? i though about doing something somewhat similar for ableton at some point, couple dynamically mappable input knobs with parameter name OLEDs. its easy there, if you use max4life, which i guess nuendo lacks..   maybe an alternative idea would be to buy an off-the-shelf controller for the basic motor faders and just build something smaller for all your custom shortcuts etc?
  12. Hey everybody, i was wondering how to split polyphonic keyboard input on several midi channels, depending on the voice number? I read through some  of the notestack source code but i can't see any implementation in NG via the scripts, right? I would have to write my own routines and recompile? Does midibox KB support this out of the box? Thinking of splitting my setup over two midiboxes anyways because together with a quite big amount of encoders my keyboard DIO matrix kinda overloads the SPI latency... so what i am trying to achieve is 6 voice polyphony to be spread over 2-3 midi channels, following the notestack rules/implementation. any advice would be greatly appreciated.
  13. Chain MIDIboxes

    Thanks man that helps a lot on where to start digging! Any background info as to why it has to be on the same PSU? would a common GND connection be enough maybe? Thats what i had to do between some other MCU boards..
  14. Chain MIDIboxes

    Hey, i also need to work on higher midi baudrates, was this somehow implemented in NG by now or do i have to compile wih my own adapted settings? @Zam would you mind shedding some light on your midi router/merger thing? i see you keep calling it USB midi, but if i just hijack the J11 pins to connect boards directly, it still is UART midi right? i would enable the second set of 4 midi ports in NG events? tried connecting PA2 or the j11 pins directly (and with pull up R) to the rx pin of my arduino, no signal. same connection works with optocoppler shields on bot sides of the cable..
  15. How did i manage to fry my STM32 disco board?

    Yeah ok thanks, will try now!   edit: thanks @latigid on, all back on track now!
