As promised earlier this year: Here is the thread for the new version of this midi controller (now called "The Ekano", because that name was still available on google sites).

More than three years ago, I started a thread about a DIY Midi Controller I built. This thing has been on my pedalboard ever since, but I redesigned it to use another microprocessor (Arduino Pro Micro). I also created a website with all required ressources (3D-print-files, drill-templates, build instructions, programming guide,...): https://sites.google.com/view/ekano/start This new version will be recognized by you computer as an input device once connected to your USB-C-Port. This being said, it can control your DAW or plugins or anything midi on your computer as well... Enjoy reading, building, programming, playing.

Yes, you can use it with any midi device, but you may have to modify the code for your specific device.

I am in the process of building a new version of the "Evening Sun Midi Controller". I will call this one Evening Sun "MC6 PRO" :-). Functions will be the same like in the first version with minor tweaks in the provided standard configuration (Preset up/down will be implemented via midi, not by emulating FS 4/5) and general cleanup of the arduino files. I have designed a new 3D-Printed enclosure and need to build the first MC6 PRO in order to verify that everything fits in there. Once everything is done, tested and documented, I will provide updated files (and start an new thread in this forum as well).

Sorry for not being more active on this forum, I just came across this old project, as I did some research on the HX Midi implementation. Just wanted to answer the questions I saw above, not sure, if those are still relevant... - First of all, after almost 3 years, this thing still runs in the original configuration on my pedalboard, so chances are, you don't need to get into the coding part, as it does what it does and it does it great. Dont change the display, stick to the instructions, get the correct components and you'll be fine. - I might (!) add an expression pedal connector somewhen. If somebody has already done it, let me know! - The reason for this is the following: The newest HX Stomp update has a feedbacker in it, so I will get rid of the FreqOut on my pedalboard and replace that with a dual footswitch (FS4 and FS5). I know, that I can have an expression pedal and a single Footswitch as well, but if I am doing changes to this pedalboard, I might also try to improve my evening sun midi controller. - Yes, there were some changes in the midi implementation in the HX Stomp 3.5. update. Obviously, the evening sun works perfectly with the current 3.71 release. - AFAIK Midi HAS to be on digital pins. Let me know, if you succesfully connected midi to other pins and were able to upload sketches without having to disconnect midi - Web Interface and such... I could do that (similar to the morning star solutions), but I'd rather keep it simple. After all, the five presets provide more than I use already (I use ONE preset of the five to change between 3 HX snapshots, one button to boost the output for solos and two buttons to change presets on the hx stomp)

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: <Update 04/2024: New version will be availabe soon, please check for new thread on this forum> 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: <Update 04/2024: New version will be availabe soon, please check for new thread on this forum> Dont hesitate to ask questions, if you have trouble getting into it.

Thanks.

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.

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?

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...

I don't know, if this has been described somewhere else, but I thought I'd share it. I wanted to use my Line6 HX Stomp with an existing volume pedal (Boss FV-500-L) and a momentary footswitch. To use the expression output of the volume pedal alone with the HX, no modifications are required, just make sure you use a TRS (stereo) cable (mono - TS - won't work). If you want to use an additional footswitch (which will show up as FS5 (!) in the HX) you need to get hold of the ring and the sleve of the TRS cable and connect a momentary footswitch. I found the easiest way to do it was to add a mono (TS) jack to the volume pedal and connect it to the jack PCB as shown. Don't be irritated by the dc jack I also added to the pedal: I added a buffer to the pedal as well, but the mod for the HX is completely passive / does not require power.
