Glad that it arrived. So I received a package from JLCPCB today with the SMD parts preassembled and I have tested it on the Atari ST core with Cubase Score and it worked fine. I have pushed that update to the github project so that anyone who wants this can order this board directly with SMD parts preassembled from JLCPCB. It's only three through-h...

Just realized I have never posted my DIY midi pcb in this forum: https://github.com/bzeiss/mister-pcbs/wiki/Midi-PCB Ah nice - you made one with the same footprint as the nano :) Do you have any spare raw pcbs available please? Are you in the EU? I have a few, but at some point, I want to add jlcpcb assembly files for the smd parts of the board. T...

Has anyone here already tested a specific capacitor setup for a longer period? I'll have all my parts ready next week to build one of those new 2.9 boards.

I'd be interested in answers from someone knowledgable in electronics to MickGyvers questions as well. My electronics knowledge is not very deep ;-) From what I see, there are two new ones in the top row which used to be 10uF, 0.1uF - 10uF, 0.1uF for the 2.5 module. Given that my understanding is that they are bypass capacitors, I'd guess that this...

I think midi in was added to minimig and atari st just earlier today. I don't have a midi keyboard at hand to test it, but I can at least say that midi out via user port works with minimig. I have just played back the brandenburg demo song in bars and pipes on my real mt-32 unit. So I really think these experimental cores are no longer needed.

Nevermind, it all magically started to work again with the official mister cores. It seems the patched ones are really no longer necessary. Not sure what I did differently.

Hm, I'm confused. From the USB pin table in mt32pi.sv it seems midi out/tx is on D-/white and midi in/rx on D+/green. This would match the old pinout. But then again, it's the first time I read system verilog. I'm guessing there is some pin switching that takes place depending on whether mt32-pi is detected? https://github.com/MiSTer-devel/ao486_Mi...

Do these modified cores from djhardrich still work with the recent main updates? I briefly checked the mt32-pi pcb schematics and it seems that the pinout from the user i/o there is different as TXD seems to be located on RX+/Pin 9 instead of D+/Pin 3. I thought that maybe this is somehow controlled by the core itself, but my mt-32 connected throug...

Just wondering, is there anything going on to move this functionality into the official cores? Especially for the ao486 and minimig, a lot of good stuff has happened since the cores were posted.

I'd be surprised if that worked without the I/O board. I'm pretty sure it's mandatory. USB 2.0 cables are to my knowledge mostly consistent in their color coding. Red=VCC, Black=Ground, White=Data-, Green=Data+. If there is some variation to it, I'd guess it would be the data+ color. I'd suggest you use a USB 2.0 cable, it's probably a little easie...

Oh well, thanks for that pointer Cebion. This of course solved the issue

For me neither backspace nor holding return/enter (I guess this is ok) works. Can this be somehow related to a German keyboard layout?

I tried Bars & Pipes on the Amiga and it worked. I started to play around though with my MT-32 Rev.0 and ao486 with the direct midi and noticed the well known buffer overflow messages on the MT-32. For example, with Heart of China and other Sierra games. Indy4 or Day of the Tentacle didn't have problems, but I guess they did not send any Sysex....

I haven't tested the Amiga core, but I recall that there is a midi preference pane in Workbench where you can enable serial midi. Have you tried that?

Amazing, this is incredibly cool. Thanks to everyone who worked on this. My Olimex board works as well. I have just recorded Midi into Cubase. My soldered cable posted above works perfectly. I think, I'm picking up a perfboard next and start to solder something that I can stack below my USB hub with a proper USB to USB connector instead of that tem...

Hey legacypixels, yes, the board would have a lot of unused space. Maybe it can be combined with a SNAC USB/HDMI adapter on the same PCB using a switch or so to justify the board size of the stack (and improve the use) ;-) Anyway, I'm looking forward to see your videos, this midi stuff for Mister is fantastic and I can't wait to play around with it...

This is awesome. Just a beginners question: I've ordered the Olimex board to tinker with the Atari ST midi. What is a good way to do the wiring? From what I understand, I don't really need the SNAC board as I don't need to 5V power. Can I essentially just use a standard usb3 cable, snip one end off and solder/plug the cables to the Olimex? Edit: So...
