MIDI player for MIDI-PAC

Today MSX hardware creator WORP3, of MIDI-PAC and Project Orbit fame, announced a new MIDI player for the MIDI-PAC.

Because WORP3 had to wait on the FPGA for the Orbit project, there was some time to work on a MID file player. At the moment there is a working player that can handle 64 tracks simultaneously and large MID files of up to 4MB if your MSX has enough memory. The player is not fully finished yet, as it's not working correctly for all MID files yet. Also the code is a bit slow and can use some optimizations.

WORP3 will demo the new MID player on the MSX fair in Nijmegen and progress updates can be found on his Twitter page.

@Igal: Looks like you want to integrate a small XG board inside your msx or even at the side of your MIDI-PAC ?
But what is the small Yamaha model #2030 board, it looks really nice

Aw, drats, I missed the WORP3 booth and MIDI player demo @ Nijmegen today. I guess I'll have to wait for the download.

My idea it's very simple.
Just use the MSX Slot for +5V, -5V, +12V and Gnd.

I have buy this card on Ebay for a good price here

The dream, make a little game with a .MID song.

@Worp3: I have make more and more tests with C-Qensr an Méridian.

I don't know if this information can help you only....
For playing All Midi without timing problem's on an Z80 3,5Mhz, i use MIDITYPE.EXE (15ko) for transforme TypeZERO.MID in TypeONE.MID standard.
This software it's small and can transforme all .MID files in Directory or subDirectory in 0,1 or 2 Midi type with one click.
It's possible change type and comeback to the original type. (all opérations are with just one clik . _, )

While waiting for your software : Hannibal:

Actually the type 0 midi files are the only one that are working just great at the moment, it's those type 1 midi files in combination with the running status and a slow MSX that is causing some problems.
Probably I will solve those problems during the upcoming week

Sorry i have invert Zéro and One

For example here a .Mid Type 1 (In second 30) => http://igalsirour.hautetfort.com/media/00/02/1502100999.mp3
The seem music in .Mid Type 0 (No problème ) => http://igalsirour.hautetfort.com/media/02/01/3679825043.mp3

All are play on Meridian ;)

Indeed, a type 1 will take a lot more cpu power to handle all of those channels, but i'm still convinced that i'm able to get it working for the most midi files

I bought a Midi-temp DoX-box so i coud use my DB-50 XG card with the MIDI-PAC.
Mine was a bit cheaper , payed € 70,- for it.

That is a very nice enclosure for the DB-50 cart !
Maybe it's a good idea to enter a XG reset code inside the MIDI-PAC because I can't see any reset button on the housing.

One side question... For tempo, does the MIDI PAC have any internal clock that can help with timing, or do you only use Z80?

For now i'm only using the VDP blanking IRQ which seems to be enough after i've changed to a absolute timer (instead of using the relative timer).
I always can use the internal MIDI-PAC timing if in the end the VDP timing shouldn't be accurate enough

With Méridian, the problème don't change with the timer of [MoonSound]

After being stuck for a while with the midi player, I just cracked the reason why does multi-track files did go berserk
Not I can finish up the player and get it out in the open
