Thank you guys!
Fastracker version 2.08, in the configuration menu can set Sound Blaster variables, especially the midi port, 300 or 330.
Then, in Advanced Instruments settings, midi channel can be activated and selected (1-16).

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 through the olimex board and my hand-soldered usb cable + softmpu in the ao486 core (see post of mine above) just outputs weird stuff now. I'm guessing the main update causes the modified cores to also use the different pinout? Unfortunately, I don't have an usb3 cable for testing at hand right now. I'm waiting for stuff to arrive.

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?

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.

Currently with the last changes the main core (Sorgelig) of AtariSt already has the midi input and output
fully working through I/O serial port
Tested with Cubase 3.1, Band in a Box, Notator3, IMS_47 and Breakthu.
Remenber put UART mode to "none".
These have been my tests:
The Minimig and Ao486 main cores (Sorgelig) have midi output working through I/O serial port , but no midi input yet.
The Minimig build from MickGiver is full working tested with Gajits Sequencer One, Bars & Pipes and Music-x.
The ao486 from MickGiver doesn´t work at all, only incomplete sounds when play a midi file and not midi input. Tested with Voyetras sequenzer Gold and Cakewalk 5 in Msdos, and cubase Score 2.8 in windows 3.11
Im using the Lotharek´s midi addon.
We are very close to having a multiplatform midi sequencing studio!

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.

Yes, mi test are from the today builds.
Midi in is not working yet in ao486 and Minimig cores
Midi out work in all cores

I have found on the ao486 core that if I turn on the midi keyboard AFTER launching the audio sequencer the midi input works perfectly.
Tested with Voyetra Sequencer Gold 4.11 and Cakewalk 5 on Msdos
Edit: Tested Cubase Score 2.8 in Windows 3.11, midi in/out and sync in/out all working

With the last update the AtariSt, Minimig and ao486 cores have
full midi I/O through I/O serial port

This is really exciting I can't wait to get Octamed wired up to some gear again. I've got a couple of questions;
- Can I access this directly through the GPIO pins on the DE-10 or do i need the expansion board?
- Would it be possible to use the serial port for a midi interface AND a port for a low latency game controller port?
- Ideally I want a midi interface without full size DIN ports and use 3.5mm TRS sockets instead so that I can fit in my home made case, can I build my own use through hole soldering and common parts or does someone sell me a suitable kit?
Thanks for all your hard work in getting this working, can't wait to start making music with this.

Hi all,
When using my real Amiga 600 I had this config:
A600->Serial Midi Interface -> midi to USB cable
USB end plugged into a client port of a powered USB hub
Akai MPK Mini controller also plugged into a client port of USB hub
iPad pro connected to the hub using the host USB cable i.e. the iPad was the host.
This worked great!
Now on the Mister I can wire the Akai, ipad and hub together no problem but the problem is I now essentially have an Amiga with a USB type A host socket that I need to connect to a hub that also has a USB type A socket and I know that's something you can't do. Any ideas how to get this all talking together?

Should I disconnect the direct midi io box from legacypixels from the user port if I load cores other than ao486 etc? Any harm leaving it connected?

I haven't seen the schematic but I imagine there's a buffer and opto-isolator on the MIDI breakout board, so I doubt you can break it

Ah nice - you made one with the same footprint as the nano
Do you have any spare raw pcbs available please?

I had an arduino midi shield lying around so lashed that up for testing!
The optoisolator is connected to the shield_5V pin and so this must be wired to the nano_3V3 header to avoid over-voltage on the fpga.

JP7_2 = Tx

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. That way, only the usb connector and the midi connectors would remain to be soldered. For outside the EU, it would probably be cheaper to order the pcbs fresh.

Hi @bnz99
I from EU (Belgium to be precise) and I'd be interested by one card if any available.
No need to get the components soldered, my friend is electronic engineer so he'll do the job for me.
You can PM me to finalize the deal.
Thank you so much in advance.

I'm in the UK so almost
No worries about the SMD - I kinda prefer SMD soldering these days (as long as it's not the realllly small stuff)

You may want to contact Nat from https://misterfpga.co.uk. He wanted to build a few. Personally, I'm not a seller and don't plan to be. So I don't want to deal with declaration forms and whatnot. It's just not fun for me

I'd like to thank you, @bnz99 I've received the PCB today. Cannot wait to get it assembled by my friend in order to use it on my Mister.
Thank again !

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-hole parts (3x midi din5 connectors + one usb connector) left to solder that way.

All good! I ordered 5 bare pcbs - thanks for sharing the design!
PS: If anyone wants a bare pcb or a built one I will have three spare I think

Made a Cubase 3 demonstration video featuring the new Dongle feature in the main Atari ST Core. Used an Akai S3200XL as the midi sound source for this
