No news about decoding MDX files on Falcon :cry:
How is it done on a PC?

I'd quite like to know how to convert it to other formats like midi with sysex files.

If you don't care to do it only on MIST (rather than the original Falcon/ST), once I finish the YM2151 clone we could make an ST core with it as a peripheral. Then making an MDX player would just be a matter of passing the control codes from the MDX file to the YM2151 ports. Rather easy.

The possibility of porting an existing X68k MDX player to this ST+YM2151 is there too, although it might be more work than working a new player from the ground up.

As for my clone, I hope I can release it during September. I am running Verilog sims on it as I wrote these lines...

UPDATE:

I have now a working MIST core with JT51 (YM2151 module) in it. I am learning GFA basic now to make the MDX player. I have produced some sounds to check the connectivity of the core and hope to get music from an MDX file this week.

I have pushed the release data of JT51 to 27th of October, so I can work out this player and some other goodies for that date.

Before going to work today I spend a few minutes advancing my MDX player for MIST and got to hear the first tune from it. It is only the first channel and the pitch is 33% higher than it should but it got me all excited anyway! You can listen to it here:



This player runs on a special MIST core with the JT51 module added to the FPGA.

Cool! which MDX file is this channel from? Will it take much CPU time? When playing all channels....I am thinking on the Falcon running a X68000 adapted game + decoding mdx music file...

This is Makaimura (Ghosts'n Goblins). The previous video had some serious issues with the pitch. I have been able to fix it and now it sounds almost 100% right:



I still have to implement more MDX commands to be able to play all files available on the internet.

About the Falcon... I have made the player for MIST because it uses my JT51 verilog module, which is a clone of the Yamaha 2151. So CPU use is minimal. The CPU only has to send commands to the chip, which is a memory mapped device. I think that MIST does not support Falcon computers yet so I wouldn't be able to connect it. Well, we can always connect the Falcon MIDI out to the MIST MIDI in and have it play it.

Sounds interesting, are there any news on this?
