Playing X68000 games with MIDI music

Folly

I tested the first timidity.cfg for DJ Tony's SC-55 sound-font from here.
Renamed the config to DJ_Tony_Roland_SC-55_1.1.cfg and placed that config inside the timidity.cfg.
Also used that soundfont.
Added the proper dir inside DJ_Tony_Roland_SC-55_1.1.cfg :

dir /usr/share/sounds/sf2

And removed the line holding --rtsyn-latency=0.04 as timidity didn't understand it.

Now I have a proper sc-55 config and left and right volume is in balance and has proper stereo.

Edit 1:
Converting the config for use with the zz_denis soundfont works perfectly.

Edit 2:
I can now also confirm that this setup works on my x86_64 VM with running on lr-px68k.
No timing issues whatsoever so lr-px68k seems to do the job OK on a regular PC's.

@Folly Cool. So it's also working for you :) .

My point is how to set up that timidity.cfg and sd.cfg what's the way to tune it etc.

I wanted to have the same for SC88 but I don't find it.

My demand to @ecto is help to know how to build the timidity.cfg file and the SCXX.cfg file

thx

Here is the manual where you might find some useful information.

As I've written before: The only (uncommented) line in my timidity.cfg is:

soundfont "/usr/share/sounds/sf2/SC55.sf2"

I have no SC55.cfg of any kind. Maybe my midi output is not configured correctly, but I can hear midi music in several x68000 and pc98 games. They seem so sound correctly, but indeed I also have a slightly irregular midi output (it sometimes slows down for some notes).

The only real problem I have are buffer underrun errors in the logs. I'm not sure if that corresponds to the timing issues, but it might.
I'm not sure how to get rid of them, but I would think that the midi daemons have to run in or close to real time.

@Folly @kelvfimer Just a small thing I noticed: the tempo changes with the lr-p68k core seem to have gotten a little better after I changed the cpu frequency in the core settings to 25MHz. Maybe you can try that, too.

kelvfimer

@ecto cool I need to check :) thx for the advice . Only issue for example Castlevania at 25 MHz has glitches and you must run it at 10 MHZ

@ecto @Folly I was speaking to a guy that fixed Etoile Princess and added some MIDI enhancement in the Core. The changes are already uploaded to px68k core. So update the core :)

@Folly @ecto take a look what we got on Emuelec with the different midi platforms in px68k

@kelvfimer

Nice to hear that this seems to work better.
I don't think it depends upon emuelec.
It probably works better because of the better computer specs, don't you think ?

kelvfimer

@Folly nope, it is not related to Emuelec. It is due to we find the proper sf2 and timidity and fluidsythn config files :) It would work in retropie, emuelec or whatever system with retroarch. The cool thins is that it works :)

@kelvfimer

Cool !
I agree.
