Korean MSX enthusiast Painkilla has developed an FS-A1-GT compatible MSX MIDI Interface based on a design of M. Fujimoto, that was put online in 1995. The interface is printed on a stylish red PCB and fits nicely into a Konami-sized cartridge. In order to make this fit, the cartridge uses S-Video connectors instead of standard MIDI ports, so a special S-Video to MIDI cable is required to connect MIDI equipment.

I love it, but the maker has no plans to sell it outside Japan, right? Sad
Well, I have my Music Module and MIDI-Pac. Can live with it Smile

As usual DIY or nothing. Question

This one lacks the official MSX-MIDI Basic extension and the 256kB memory mapper for Turbo-R ST.

Was that 256KB extension useful at all for the ST?

If you want to run Unknown Reality from a harddisk, some more than 256kB is handy Wink

Hmm, maybe not, but it's always nice for DOS2 or MemMan to have. But ofcourse it's better to upgrade the internal memory first on ST Smile

Can this midi interface be used for other msx computers or only on the turbo-r ST ?

In the article they are using it on a MSX 2+, so yes it should work on other systems as well...

TurboR ST is the easier of all MSX to upgrade to 512KB.

And as i understand it it works as the u-pack for the Turbo-r ST, with out the Mem expansion of 256Kb.
But what programs do the Turbo-r Midi support, and which programs work also on other MSX computers ?
Like Smid is a midi player for the turbo-r but would it work with this interface or is it turbo-r only.
The real question is if this midi interface was made again with what programs can i use it.
Or would it be nice for turbo-st owners only, because of the programs for it ?

@roadfighter: yes, you are right about Mu-pack, additional 256kB RAM and MIDI-ROM as in FS-A1GT.
Ofcourse programs designed for Turbo-R will not work with this interface on MSX2/2+ like SAWP and SMID. Instead, you could use MIDRY. Look for my WIKI contribution over here

One could try (if not done already)... Some programs might look for specific hardware instead of the MSX model...
*IF* Smid is looking for MSX-Midi and not for MSX model, it might work... But ey, I'm just yelling something about stuff I do not own Wink

I think it's best to use with Turbo-R ST or as second MIDI device for Turbo-R GT (MIDI-THRU function). The default Z80 running at 3.58 MHz is too slow for complex MIDI data, that's why Bit2 released the MIDI Saurus in the past which contained it's own Z80 processor and memory buffers. For Turbo-R this extra CPU wasn't needed anymore because of the faster R800. Anyway, my Mu-pack runs well with MIDRY on my 1chipMSX running at 8 / 10 MHz. :-) But some programs do require the R800 CPU because of the needed opcodes...

I remember a guy - Klaas de Wind - who owned that Bit2 thing along with the synth module which was (according to him) the one Bit2 built their interface around.
It was a really poor and crappy synth. Even an MT32 was caviar compared to it... Too bad I was just 16 or 17... Can't remember much from that era...

MIDI Interface 3 — I am interested in it.

Already have a DalSoRi, but it’s a really nice cartridge that I can recommend to everyone.

Hi Grauw, great news! My Korean friend is almost ready with the design for the MIDI interface 3 and asks how many people are interested to buy one. After this project he will focus on DalSoRi version 2.

So, how many items will you and other people buy? Price will be around 125 euro including shipping. Price could be lower if there's a higher demand. Maybe you could combine orders as well.

It’s worth noting that it is not an MSX-MIDI standard interface because the MSX-MIDI ROM is absent. Due to its absence, the presence can’t be detected in the standard way described by the MSX Datapack and some software can have compatibility issues. Also the alternate I/O port mode that external MSX-MIDI interfaces are supposed to initialise to is not available, so it doesn’t work on turboR GT because it conflicts with the internal MSX-MIDI interface.

I added a MIDI Interface 3 extension configuration to openMSX so developers can test in the emulator.
