it works! for some reason i ran into issues with uploading onto a clone mega328p. i tried the steps on a clone mega2560. i thought i had bricked them both, leading me to an arduino stack exchange post by nick gammon on 'Have I bricked my Arduino Uno? Problems with uploading to board'. I ended up using one of his sketches "atmega bootloader programmer" and reinstalled the bootloader for atmega328p. after that i could upload sketches again. i then followed your steps again for dual booting. i can now easily swap between the normal mode and midi mode. took me a couple hours but i hope my comment saves time for some one! especially for those who own cloned boards!

i was able to fix this by reprogramming the bootloader (nick gammon on stackexchange post on have i bricked my arduino) then flashing mocolufa

I think hes still working on it.. I pop back over here from time to time to check on progress 😅

It's true! Things will really start moving when I work up the nerve to fork out a bunch of money for a prototype run. Luckily I'm prepared 😎

@@CorvusPrudens rock on best of luck to you people still interested!

@@CorvusPrudens 😁👍 exciting..

Four months in the future (hopefully for real this time)!

I've thought about it several times over the past year or so. I have an issue though where I'd want the video to be really nice, even if it's just a little update. And when it comes to it, the time spent on an update video could just go towards getting it done instead! I'm pretty happy with my design now, though. I'm mostly in the stage of rounding up the last few little hardware issues before it's pretty much as good as I can make it.

@@CorvusPrudens That's great news! I completely understand, it makes sense that you don't want to derail the module's development to work on a video. Thanks for the reply, it's great to know this is still being worked on and is near completion. Will it be sold direct by you on your website? (Is there a website?) Or how will these be sold when they become available? Really want to jump on the first batch when it is ready!

which board?

@@erende44 the uno

Well, the USB class detection mechanism is just that pin that you can put a jumper on. Maybe there's some electrical interference going on there? Try tying it directly high or low depending on what firmware you want and see if that does anything.

same question here

Yes! Although it's been quite the process to make a real product. I've gone back and forth on a few design decisions, but I've finally settled on something I think is reasonable. It's all tradeoffs really, and some of them are kind of painful!

I'm a hardware/electronics designer myself so I understand the struggle, especially with the global supply chain issues. Either way, I'm glad you're still planning to sell this module! I'm looking forward to playing with a EuroNES module once they become available!

ngl I got real scared for a second there. Still coming along though. I've had to reign in the scope a bit so it doesn't cost $500 (I've made a few prototypes that are straight up monstrous).

It looks like an internal fuse is written (device is write protected). There might be ways to change that with the dfu tool, but I've never had to do that before

@@CorvusPrudens dang it… i have a spare board lying around, i’ll try it with that, but first i’ll use it to reset the first one to its factory state

Not yet! But it's not abandoned.

@@CorvusPrudens fantastic!!

also - just in case you still want any further evidence of interest - LOOKMUM made a viddy pursuant of something similar and mentioned it as being "everyone's dream": czcams.com/video/xd72kksv2zg/video.html

It's still in the developmental stage, but it's coming along. It's been a lot of work figuring out how it should fit within a typical eurorack setup, but I think I've finally gotten it to a point I'm satisfied with. Now it's just down to design refinements and waiting for my chips to be available 💀

@@CorvusPrudens ahhhh im so SO glad to hear it!! Let me go ahead and subscribe to your channel so I can stay plugged in and motivated to make music by way of any updates!

Funnily enough, I'm still working on it 😅. The design has changed quite a bit from this proof of concept.

Did you put a jumper on to set it to serial mode? By default, it'll just show up as a MIDI device which can't be programmed with the Arduino IDE.

@@CorvusPrudens yes I am programming it but once it is programmed it does not seem to register with my device. I am trying to get it to send midi notes to my iPad.

@@CorvusPrudens hey there I am about to give up on this. If you or anyone can guide me in building a MIDI footswitch that sends note messages to my iPad to control my backing track app I would be so grateful.

@@adinwalls Use a midi library and use a five pin midi port and a midi to USB cable. Your Arduino won’t be native midi, the cable will take care of that. works fine with PC and iPad

Working on a video right now, actually :)

@@CorvusPrudens 😊 awesome.. Does that mean its release time?!

Absolutely not 😭. I still need some help from a couple artists and some UI refinement. But we're getting somewhere 🤣

@@CorvusPrudens haha wish I could help.. ❤😊 enjoy the process

Aw thanks so much! As I've played with it more, I've been wanting to expand the I/O quite a bit. My current plan is to have 2 CV and 2 knobs per channel, meaning it would have 5 columns of inputs on the base module. That would put it at more like 20 to 24 HP. Obviously the size and cost is increased a bit, but I feel like the huge boost in playability and ease of use is worth it.

@@CorvusPrudens Sounds awesome! Thanks so much for the update and Godspeed!

Things are definitely going well! The final design is coming together now. I've said it before in other comments, but I'll be making an update video soon!

That’s really exciting. What an amazing project.

Hey thanks! Well, if you're already familiar with FPGA design, then the rest shouldn't be too bad at all. I guess it depends on what your sticking point is though -- have you done circuit design / layout?
