Sorry, did not find a button for PM's, so you will have to ask questions right here ;-)

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.

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...

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.

Thanks. I will integrate this as the central element in my rig, so here is the preview:

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:

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?).

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)

Fixed the issue - I was able to get rid of the duplicate PC messages, works again. Obviously, the older HX firmware was more tolerant in accepting a second PC message sent immediatly after the first one.

This was a perfect recommendation, thanks - I did the backup/factory reset/restore process and I dont recognize the issues with the "frozen values" any more. However, some program changes (with even numbers, very strange) did not work, so the HX reacted to Program 1, 3, 5 etc but would always jump to program 1 when I wanted to trigger 2, 4, 6 etc. So I installed a midi monitor and it seems that the arduino software I programmed always sends two program changes.

Well, I guess, I have to review my 3 year old code for that ;-) Thanks again! Matthias

I found a strange behaviour of my HX Stomp (Firmware 3.11) that I control with an external Arduino-based MIDI Controller (for program changes, snapshots and block activation). The problem does not occur with another (coomercial) Midi-Controller I have, still this is very annoying, as my complete rig is build around this controller AND IT USED TO WORK FLAWLESS until I updated to 3.10/3.11. Directly after switching the hx on, everything works fine: Block activation via midi works AND is shown on the HX (blocks greyed out or activated) Values (e.g. Delay time) can be changed AND these changes are visible on the HX After a progam change via the Midi Controller Block activation and value changes still work but are no longer displayed on the HX See a video here! Probably, my Arduino controller is struggeling with the changes in the midi implementation introduced with Release 3.10: New and Improved MIDI Implementation Helix Floor, Helix Rack/Control, Helix LT, HX Effects, HX Stomp, HX Stomp XL MIDI Snapshot changes on CC69 that are received during preset loads will now be buffered and executed once the preset load is finished. This means that you can send a MIDI Snapshot change immediately after a PC message to effectively load a preset with a different Snapshot than it was saved with Bank/Preset/Snapshot Up and Down messages how properly work via incoming FS1/FS7 emulation MIDI messages FS1/2/3 emulation MIDI messages can now be momentary for HX Stomp (values 64-127 = press; values 0-63 = release) Stomp switch emulation MIDI messages now work while in preset or snapshot footswitch mode New MIDI message (Helix Floor/Rack/LT/HX Stomp XL): CC71 engages the MODE switch New MIDI message: CC 72 value 64-127 = next preset, value 0-63 = previous preset New MIDI message (Helix LT, HX Stomp, HX Stomp XL): CC 73 toggles between Play and Edit views Anyway, I will look further into this. Even if this might be related to the Arduino midi implementation, any help is highly welcome. Anybody else have similar problems? Please let me know!

It works perfectly. The sweep for a wah is different, but completely acceptable. And... You can configure it to automatically go off in tow or heel position!

Just a quick "thank you" for adding the Tone Sovereign to the 2.8 update. A clone of the KOT was my last analog pedal on my board and has been the source of my main crunch sound for a couple of years up to now. I did an A/B with the Tone Sovereign and while there is a slight difference, I cannot tell which one is better (and forgot which one I was on after some playing).

No, the hx stomp only has 3 buttons...

The vol pedal needs a trs cable. Could have made a trs into ts and trs as well. But this way, I only need one long trs cable and a short ts cable. Stuff, I always have in my cable box, so no need for special cables, which I tend to forget at home...
