Hello everyone. I'm in the middle of a project and need some more DIN modules. Unfortunately they're out of stock at modular addict. Is there another seller, where I can purchase the modules? I live in Germany and. I could't find another seller besides modular addict. Thank you in advance! Have a nice day! Frederik

SSl Blog Post 02 Hello again, Last time I wrote about the design process of my console. In this post I want to focus on the electronic part. In the last couple of weeks I searched for the right knobs, faders and pots for the project and I nearly found all I need. The pots were the simplest part. I opted for the Alpha 10k Lin https://www.musikding.de/Alpha-Potentiometer-16mm-10k-lin Each channel will have one motorized fader. Here I choose the PSM01-082A-103B2. https://www.mouser.de/ProductDetail/bourns/psm01-082a-103b2/?qs=MAZTpT1IVl8rvdecO07rRA==&countrycode=DE&currencycode=EUR 14,76€ when I buy more than 25 is a good deal I think. The ones from alps are very pretty, but with prices over 30€ per piece they are quite expensive especially because I need 33. For the bus channels I opted for simple 60mm faders. Also 10k lin, not very investing. https://www.reichelt.de/schiebepotentiometer-stereo-10-kohm-linear-rs60n12-lin10k-p73870.html?&trstct=pol_1&nbc=1 The knobs where a little harder to find. For the Solo Cut and Rec knobs I want to have knobs with Leds which I can connect to an DOUT module separately. So I could press Solo on the console but deactivate it inside my DAW and the LED would follow my actions. After quite a bit of searching and some phone calls with distributors I finally found these. https://de.farnell.com/nidec-copal-electronics/cfpb-1cc-4w9/drucktaster-spst-0-005a-5vdc-panel/dp/3498758 The knobs inside the channel strip are still to be found. The need to be snapaction knobs with a white cap with the measurements of 5mm per side. I couldn’t finde the right ones even after quite some hours of searching. Maybe I’m just searching without the right search terms? Maybe someone of you knows the answer to that problem I didn’t start the search for LEDs just yet. I think and hope these should be easy to find. For the modules I chose STM32F4 for the cores, AINSER 64 for the pots and faders, NG MF for the motorfaders, DIN for the knobs and DOUT for the LEDs. I especially need quite a lot of AINSER modules and I’m still figuring out a way to connect more than two to an STM32F4. I found some blogposts but could get the answer out of these. They suggested it should be even possible to connect more than three? I obviously want to use as less cores as possible. This build will be huge either way. I can connect the MF modules directly to a pc without a pc. Thats what is written on the website. But how do I connect these to the pc? Via midi? There is no USB port on these modules right? And I also should cascade them. I need 5 modules. I want to use 33 motorized faders and that’s quite unfortunate because every mf module only supports 8. How do I cascade these modules? Also via MIDI? The last problem I ran into is the meter bridge. This could be a whole blogpost of its own… My plan was, or partly still is to use 10 7“ displays connected to a 10 times HDMI splitter, which tells the PC there is only one REALLY big screen. But after buying quite some displays to test out I figured out 90% of the screens for sale online are totally crap! Ok, I searched for quite cheep ones, but I need 10 of them and if I had unlimited money I would buy the original ORIGIN console… But I don’t have access to unlimited amounts of cash so I need a cheap display which works. The first one I ordered was the perfect size and easy to operate. But I only could see the image looking from one specific angle. Moving my head just a little bit the whole display would turn blue. The second one was advertised to be 7“, but the one that were delivered to my was only 3,5“…are you kidding me? Out of anger I searched for analog VU meters. I really like the looks of these and figured out these work with voltage. Is it possible to drive VU meters with a midibox module? Maybe with an AOUT module? So many more questions but I already wrote a whole book here…sorry for that. If you still reading in this point thank you very much! Have a nice day! Frederik

How do the DIN and DOUT boards identify themself with the core board? What I mean, is will the order of the boards not change after each power cycle?

Hi Fellow DYI-ers, I have 4 DIN, 4 DOUT, Midi IO, and MBPH_DIO_MATRIX_V1; all fully assembled and a MBHP_CORE_STM32F4 module for converting an old Church Organ to play Virtual Pipe Organ using Midi. I have Download all files such as MIOS_Studio_2_4_9, en.stsw-link004 Utility, en.stsw-link008usb drivers, mios32_bootloader_v1_018 and SetupSTM32CubeProgrammer-2.4.0 all of which are installed. I followed the direction on http://ucapps.de/mbhp_core_stm32f4.html. with success with the exception of running MOIS Studio Please look at the picture below and I attempted to run Mios Studio This 1 picture is the result of when I 1st open Mios Studio. Everything looks ok. The 2nd picture showed my file path to upload the " project.hex file to MIOS Studio This picture shows after my file path has been selected. The final picture shows the result after starting the upload The only device connected at this point was the MBHP_CORE_STM32F4 only. Please help me. I am completely new to this. Do have to module connect the organ keyboard prior to monitor the midi msg.

I have my MBHP CORE V3, together with 4 DIN and 4 DOUT boards. I am assuming all 8 of these boards will connect to the same port on the MBHP CORE V3 board. So am I correct in thinking I can use a single y-cable, and connect 4 DIN and 4 DOUT boaards in a cascading fashoin, and connecting the middle of the Y-cable to the CORE. I intend connecting 128 LED's and 128 momentary switches to the boards. What I do not understand is how will I know in which order to place the DIN boards, as well as the DOUT boards, because to me they all look identical. Am I missing something obvious? The boards were built for me by a friend. Please advise.

In case you are looking for an inexpensive and an easy-to-build MIDI THRU solution, Andy has built a new PCB for this job! :) It is good for low-latency MIDI distribution, supports normal and TRS MIDI connectors and offers a visual MIDI traffic indication using a superflux LED. Also, it is multi-chainable to 8x MIDI DIN and 6x TRS MIDI or even more outputs. Using these boards, you can extend your SEQ MIDI OUTs to drive a lot of MIDI synthesizers with minimal latency! :-). The USB port is intended for easy portable jamming setups, or you can alternatively power it via a pinheader. We've also included a build photo tutorial. https://www.midiphy.com/en/shop-details/0/35/ Enjoy and many greets! Peter

A Friend built me a "Core" board, with 4 DIN and 4 DOUT smaller boards. I am looking for the schematic for this board, to see if I can possibly connect some POTS to the board as well. I am also looking for the circuit diagram of these boards to see how to connect everything. When I search for MBHP CORE V3, I don't see the diagram for this board, I see something else. Please help me locate the information and circuit diagram / schematic, so that I know what to connect where. Thank you in advance. Regards, Brian.

I'm looking to build my own custom board, but I want to make sure I have the core concept down for a basic DIN, before I move on to adding more components. Totally new at doing my own circuits, so any input would be appreciated! When I'm done I'll post it all, in case it's useful for anyone. Thanks! basic_din.pdf

Okay, my google fu is not up to par, and this is my first go at KiCad, but: I've been trying to find schematic files I can open in KiCad (i.e. not pdf's) for the Midibox modules. How do you all do this? I "think" it's possible to import the .brd files in KiCad, if I use the nightly build. Not sure what's an efficient work flow.

I need one additional DIN for my midification of an old Conn. Either the board, the kit (Smash TV), assembled, or the files to make the board or a schematic. Adding a third keyboard to my setup and no room left on my 7 DIN boards. Thanks Jay

Hi everyone, I am very new to midibox, I have a DIN module connected to a stm32f4 core with logictrl.ngc loaded as the default patch. I am trying to get it to work in pro tools ultimately, but I havent been able to get it to work in logic either. I have a single button connected to D0 which mios is responding to, recieving this message [2095799.673] 90 18 7f Chn# 1 Note On C-0 Vel:127 but no response from pro tools. It's set up correctly in Peripherals (set for hui, mios in, mios out) I know there is probably something I am missing, but I'm having trouble finding anything specific to logictrl.ngc in the tutorials or the forum Any help is greatly appreciated! edit: it is working in logic, but still not in pro tools, the versions i have tried in are pro tools 10 and 11

I am brand new to midibox, I don't have any modules yet, as I am trying to figure out which ones to get exactly, I haven't found a sure answer to what I'm looking for specifically by looking in the forums and the general information on the ucapps site, maybe someone could help. I'm trying to make a controller for Pro Tools using 3 MF_NG modules , for 20 channels/faders total since it would be installed in an existing 20 channel console, but I'd also like to have buttons and leds for record enable, channel automation, as well as transport controls and automation selectors (read, write, latch, etc.) as well as leds for the record lights, which for me would be about 60 buttons, and 20 leds at least for the record enable lights. at least Ideally it would use mackie HUI, but I would be fine with using MotorMix if that works better. I'm trying to find someone here who has successfully made a controller with both motorfaders AND buttons/leds who could let me know what modules I would need My first thought was to get a STM32, and then connect the MF_NG modules and DIN and DOUT modules, but in the MF_NG thread there was a post that made me think that might not work. I posted the quotes below, they are from 2012, maybe this is dated? Would it be different since I am only using 3 MF_NG modules? Could I use just a STM32 or would I have to use an LPC17 and MIDIO128? If I did need to use the MIDIO128, would I have to use the LPC17 or could I use it with a STM32? My understanding is that the STM32 is an upgrade in a lot of ways to the LPC17, and doesn't require an external burner. My goal is to keep everything as simple as possible since i'm completely new to midibox. But since it's Pro Tools we are talking about, things can't be so easy.. Sorry for so many questions, any help is greatly appreciated!! Even if i had to use older modules, that would be okay! I just don't want to get/build the wrong components.. I also wanted to make sure this kind of configuration is something other people have gotten to work in pro tools Here are the quotes:

hi Im having a big headache with DIN module the configurAtion is 2 chips 74hc165n I only need 8 buttons on my midi box 64 the problem is when I press 1 button nothing happens but..... If I press 2 at the same time yes... I mean it send the midi command, for example if I send to ground pin 3 of the 74hc165n nothing hapends but if I send to ground pin 3 and 4 at the same time it send the midi command... Same with 4 and 5 and so on, it's so strange, I have built 5 midi boxes and never hapends something like this, I have tried 3 different PICS with the same results, what can be the problem? thank you very much

Is there a possibility to let the DIN and/or the DOUT react inverse? Background: Usual DOUT LED is lit by switching HIGH on the Output O0-7 of the HC595 Shiftregister. I wold need a possibility to switch to LOW so i can inverse the Polarity and Connect the Cathode towards the Shiftregister and the Anode to the 5V supply. And the same for DIN. Connecting the Resistor Network to GND and switching the Supply "VD" towards the Inputs I0-7 of the HC165 Shiftregister wold inverse the reaction. So it wold be nice to have a possibility to inverse the reactions in Software... is that possible in some way? Thanks novski
