MarshallArts Posted October 6, 2021 Share Posted October 6, 2021 Hi, not quite sure where to put this, however, I though it was worth sharing. I am close to finishing a DIY controller for my HX stomp based on an Arduino nano. Building it is easy with some drilling and soldering skills, changing Midi commands (and sequences) according to your preferences is easy. It cant do all the things a morningstar MC6 can do, but it comes with a 4-line Display and 6 switches, so it may look similar. All you need is a Hammond 1590xx enclosure, an Arduino Nano, an LCD display, a midi Jack, a DC power jack, 6 momentary switches, and a few resistors. It's actually so simple, I am thinking of not even making a Circuit board for it. Overall costs will be around 50 €. I would provide the software for free, once it's done. If you would like to donate what it's worth for you, I would be thankful ;-) Here is a picture of two Banks that are already working: What it can do: Button Action: Single Press, Long Press Toggle Values of Blocks via Midi CC ("Toggle Solo Boost" in my example) Activate/Deactivate Blocks via Midi CC Change Presets (via Midi PC) Activate/deactivate the Tuner Change Snapshots Change the Footswitch Mode on the HX Stomp (Snapshot Mode, Preset Scroll mode, Preset mode, Stomp Mode) Downsides: No webinterface - to change midi, you will have to change the arduino code (it's actually easier than it sounds) No Midi in, so it's a one-way-street from the controller to the HX or Helix or whatever device you are using Anybody interested? And here is a preview of the enclosure (based on am Hammond 1590xx) 1 1 Quote Link to comment Share on other sites More sharing options...
artkrz Posted October 7, 2021 Share Posted October 7, 2021 I'm interested! Please post your code and wiring diagram to GitHub. I actually started planning my own Arduino midi foot-switch controller but I would be for Boss RC-5, way simpler as I just would have momentary switches without display and just send predefined CC messages. Anyway, are you planning to do MIDI thru as well? Quote Link to comment Share on other sites More sharing options...
MarshallArts Posted October 8, 2021 Author Share Posted October 8, 2021 I will post the code in a few days, when everything is working and leave a link here. I am not planning to provide midi through but would be interested, what you would use this for (I assume more than one device and another one, that is lacking a through jack?).

MarshallArts Posted October 18, 2021 Author Share Posted October 18, 2021 It's done and it's working great! Besides the Arduino Nano and the LCD Display, there's only two resistors, six switches, a Midi Jack and a power jack - that being said, I decided to build this without any additional PCB. The wiring can be found below. I will wrap up the code and put it on github later this week. As a special bonus, I will provide the 3D-printed parts (the Nano holder, so you have access to its USB port and the display pcb standoffs/distance tubes). If you build this, make sure you have some 2.5 mm nuts and bolts available (I bought this one: https://www.amazon.de/gp/product/B075WY5367/ref=ppx_yo_dt_b_search_asin_image?ie=UTF8&psc=1) Sample Video: 1 1 2 Quote Link to comment Share on other sites More sharing options...
codamedia Posted October 18, 2021 Share Posted October 18, 2021 Great job...As a bit of a tinkerer I've considered building my own midi controller to conform to my needs.... this might be the thread to get me started. Quote Link to comment Share on other sites More sharing options...
soundog Posted October 20, 2021 Share Posted October 20, 2021 Holy mackerel! I've built a number of MIDI controllers over the years, but you really knocked this one out of the park!! 1 Quote Link to comment Share on other sites More sharing options...
MarshallArts Posted October 20, 2021 Author Share Posted October 20, 2021 Thanks. I will integrate this as the central element in my rig, so here is the preview: 1 1 Quote Link to comment Share on other sites More sharing options...
MarshallArts Posted October 28, 2021 Author Share Posted October 28, 2021 I wrapped this up for my live rig: I will most likely stick with the configuration in bank one (3 Snapshots on the bottom row (buttons D-F), scroll HX presets up/down (buttons A/B) on the top row and a solo boost (Button C). This means, I will not change the code over in the near future, but document it well enough for everyone else to adjust it to their preferences. You can find it here: https://github.com/mfunky/Evening-Sun-MC6 Dont hesitate to ask questions, if you have trouble getting into it. 1 2 Quote Link to comment Share on other sites More sharing options...
jonsolberg Posted January 15, 2022 Share Posted January 15, 2022 Great project, will build one myself. Is it possible to get a drilling scheme for the Hammond case and the stl:s for the arduino holders? Quote Link to comment Share on other sites More sharing options...
MarshallArts Posted January 17, 2022 Author Share Posted January 17, 2022 I put everything in a folder: https://drive.google.com/drive/folders/1aPccKfk_vpsLlXT--HC1rol7yhRKhfzw?usp=sharing It's not a drill template, but the CAD-Drawing I created as a basis. it's not to complicated, just the square hole is a bit annoying...

lipeefalcao Posted January 18, 2022 Share Posted January 18, 2022 Hey @MarshallArts, I'm gathering all the information to build the Evening Sun but still have lots of doubts. Is there a way to get in touch with you easily? My first doubt: Can I use the "Arduino Nano V 3.0 Atmega 328 Rev3 R3 V3.0"? Does the code works fine with "Oled 0.96 I2c Ssd1306 Lcd Arduino display"? It's a little bigger than the one you got. Another doubt I have.. Do I need something else to make it work or I just need to wire it to arduino and get the touchdown?!

MarshallArts Posted January 31, 2022 Author Share Posted January 31, 2022 Hi... I sent you a pm with my contact information. For the rest of the questions: The Nano should work fine. Changing the display means changing a library and getting into the code. You need some experience with programming to do this (it is absolutely possible, though). The display seems small, though and I have had bad experience with readability of those on stage or in sunlight. You need an enclosure, the jacks, buttons, a display, the arduino, the 3d-printed holder, wire and solder stuff. No extra circuit board required.

mattzz Posted January 31, 2022 Share Posted January 31, 2022 Awesome build! I built a simple two button MIDI controller based on the Arduino mini pro specifically for the Stomp (https://github.com/mattzzw/midi_muppet_hx_2btn). Feel free to check out the code, maybe you find something useful (e.g. midi channel switching and eeprom storage of configuration). Regarding web-editing I was thinking to switch to an stm32 based board (black pill or blue pill) using webserial in the browser in order to build something similar to the MC3. On the other hand it would probably be way easier using a ESP8266/ESP32 providing wifi and bluetooth capabilities. Way too much cpu power for a simple midi switch - but hey, who cares, right? It's 2022 so a simple midi pedal should be capable of opening up a wifi access point, providing you with a nice web gui... ;-) Quote Link to comment Share on other sites More sharing options...
natewan Posted June 16, 2022 Share Posted June 16, 2022 Thank you for the build idea! Any reason for having the Midi Jack on Digital Pins? Your notes mention having to disconnect midi while uploading a sketch. I am new to this and cannot find any info about what happens if I upload a sketch using the 5V and GND Pins on my Midi Jack.

ronnyxavier85 Posted August 29, 2022 Share Posted August 29, 2022 hello good afternoon sorry for the english... I can change it to use a 2-line and 16-column display or will I have to buy a 4-line and 20-column display, could someone help me I don't understand much about arduino I'm a beginner Quote Link to comment Share on other sites More sharing options...
GetFightedMikey Posted October 30, 2022 Share Posted October 30, 2022 Hey man! I have been working on building this exact same thing from your designs, and am just having a bit of trouble with the display. As far as I can tell, ive got the same screen as you, however its not displaying any of the info from the stomp, or the mode that the footswitch is in. Currently the display is lit up and just has 2 rows of blocks displayed at all times. Not sure if you're still active over here or whether you may know, but any pointers would be much appreciated! Cheers! Quote Link to comment Share on other sites More sharing options...
GetFightedMikey Posted October 30, 2022 Share Posted October 30, 2022 Well, I actually managed to figure out what the problem was, I had my LCD screen address completely wrong! Now that I have got that part sorted I am really looking forward to diving in and using it! The looper mode is really awesome, I just need to slightly alter some of the other preset banks to suit my own style. This is a great project though and I have really enjoyed working on it.

jpas Posted December 25, 2022 Share Posted December 25, 2022 Hello, nice project! I would like to do mine even if i'm not into arduino stuff... I would like to ask what if I would insert the plug for the expression pedal like in the MC6? Thanks Quote Link to comment Share on other sites More sharing options...
Smacmag Posted January 13 Share Posted January 13 (edited) hi, great works!!!!!! I have build this fantastic project!!! It s a full progammable controller, so how program Pc and Cc change? they are no menu to do this? thank you and great work again!!!

aaskia Posted March 5 Share Posted March 5 Hello! I have the two button arduino based Midi controller. Since the 3.5 update, it doesn't work properly as it did. Some functions are gone. I'm planning to make this pedal, if it works properly after the 3.5 update. Do you have any experience? Quote Link to comment Share on other sites More sharing options...

I'm curious what parts aren't working properly anymore. Did Line6 change any MIDI stuff in the 3.5 update? Quote Link to comment Share on other sites More sharing options...
