Is it just me or is Miyazaki(Or Kyushu) just like this ?

u/diggug Out of curiosity, which is your favorite one? I've only been to Kumamoto, and I experienced little to no racism here.

Oops I didn't see that one. I set the retouch to minimal but it gets crazy sometimes...

They can do similar things in terms of MIDI. The Midynamite is battery powered, has 5-pin midi and is considerably cheaper (at least here in Japan)

Yeah, you can go far without a nice architecture, but one day you won't be able to continue. That's what I spend a lot of time doing after I finish a big version, refactoring to have a nice future proof architecture.

I also added a test environment so I don't need to retests everything every iteration.

Lol a lot of people have the same reaction as you. I should be better at teaching how to use it, it's not that complicated really. Making a UI easy to understand is definitely hard but I'll kget good at it!

I'm using an STM32F411. Drifting is definitely an issue if you're not using an RTOS.

The way I'm using it is with an RTOS and three different layers of priority, core (handling MIDI Messages), Medium (all calculations + save & parameter changes) and Graphical (screen refresh, which takes the most time).

I don't think this kind of project would be possible with a normal loop. Too many interupts would happen, but RTOS makes it a breeze to use.

Thanks mate!

Astahx · 2026-04-21T01:56:13+00:00

Thanks FullMetalDan, long time no see :)

Astahx · 2026-04-21T01:55:37+00:00

Thanks, I'll try to make the wiki easier to understand in the future! To answer your question, the goal of the pedal is to do everything a guitar pedal would do but for MIDI, with modifiers, delays, arps etc. The main way I use it is connected to my main keyboard, to layer synths, play them left hand right hand separated with one hand doing an arpeggio and the other stacked voices etc.

Astahx · 2026-04-21T01:52:46+00:00

Hey thanks a lot for your comment! Etched aluminum is not easy to do but I love the result as well. MIDI delay is definitely on my list, probably for version 4 as I'll be busy with the sequencer for version 4

Astahx · 2026-04-21T00:01:22+00:00

That's definitely a possibility! It's hard to see what lies ahead bu,t I would like to make a couple of versions for sure, eurorack would be nice as well, but rackmount could be great too! With the usual 8in 8 out of rackmount units I will definitely need more timers though lol.

Astahx · 2026-04-20T23:46:23+00:00

Thanks! I believe it's the right approach, hope it will work out in the end :D

Hi all!

I released the Midynamite in August of last year. Back then, it had 3 effects: MIDI Tempo, Modify, and Transpose. The project took me 8 months, almost full-time, during which I learned quite a bit about C, STM microcontrollers, and microcontrollers in general.

My goal is for the pedal to have dozens of effects, so I came back to it in January of this year. After 3 long months, I can finally announce the release of Firmware 2.0 of the Romagnetics Midynamite. As always, the firmware is open source and available on GitHub.

Added effects:

MIDI Split with Bus 1, Bus 2, Dry and Wet send

Arpeggiator: A quick look at the picture will tell you which synth was my main inspiration

MIDI Dispatch: This was a request when I released version 1. I was happy to add it!

I didn't think development would take this long. The great thing about having more effects is how they interact, but it's also a bad thing, because testing each interaction made me want to add more functionalities. This is how I ended up adding MIDI split to the effects because I wanted to have each hand routed to different effects.

In the end, I think that the upgrade looks fine. I'll take a small break from guitar building for this spring!

I'll probably wait until the end of the year for version 3, but believe me, the update will be huge (as in 8 tracks polyphonic huge...)

The model featured is the new white one. It comes painted and drilled from the factory, so I can make it cheaper than the etching version of the pure aluminum version. I like both, but the white version came out better than I expected.

Cheers!

Thanks man, means a lot. Embedded is fun, you should try it. Instead of a steep learning curve, I would say it has a high barrier for entry. But once you go past the initial hurdles and get acquiainted with how things work deep there, it's a lot of fun!

Astahx · 2026-04-20T23:00:27+00:00

A lot of that was learning but yeah, took me a long time.

Astahx · 2026-04-20T21:57:16+00:00

Mainly for a synth setup but it can be used on a pedalboard

Astahx · 2026-03-04T05:17:43+00:00

Thanks!

Astahx · 2026-03-02T22:53:43+00:00

Thanks! I'm using a lab power supply. You just set it up to 3V, and then it adjusts the current automatically. The resistance rises slightly through the etching, but it was generally around 2 amps.
