MIDIPLAY for MIDI-PAC v0.50

Just before the fair in Nijmegen MSX hardware developer Worp3 was talking about the posibilities of having his MIDI-Pac play MID files. He started coding straight away and was able to demonstrate his progression at the fair. As of now the music hungry audience is able to give this MIDI player a go. Note that the player is still in testing phase and far from complete. Worp3 just couldn't wait any longer to share.

The player will work fine with most single and even multi-track midi files, but:

  • You will need to upgrade your MIDI-Pac to version 0.7.0
  • It can handle a maximum of 64 active tracks
  • It will not look at the denominators yet
  • There is no difference between 50Hz and 60Hz yet
  • For now a fast MSX is recommended because the player isn't optimized yet.

Don't forget to reset your MIDI equipment so now and then !
Some midi files can really change a lot of settings inside your synth which can result is strange behavior of your synth when playing other files. See your synth manual on how to reset it.
I will implement a way to use a default GM, GS or XG reset method later Smile2

There is no difference between 50Hz and 60Hz yet

'yet'? I'd say it's a blessing that music plays equally fast at both frequencies..

Something went wrong while copying the text as on my website you can read the following "it will not adjust for the 50Hz/60Hz difference yet"
So at the moment you will notice a difference between the 50 and 60 Hz mode, i will fix this in the next version Wink

@KdL, maybe I will but first I want to fix/finish the open points.

Did someone tried the player on a standard MSX2 (@3.54 Mhz) ? If yes, did you experience a lot of slowdown during playback ?

Can someone try the new 0.51 version for me ?
I've added the 50Hz / 60Hz detection and it should play at around the same speed for both frequency's !
I can't check it as my one-chip isn't reacting on this vdp setting Sad

Did some tests with version 0.51 on my Tutbo-R ST, 50hz / 60hz play the same speed.
Used good old Memman 50/60hz tsr.

EDIT: speed is affected when switching during playing a midi file.

Great, thanks !
It's normal that the speed is affected while switching between 50hz and 60hz during playback. This because i'm checking for the frequency before the midi file is starting playing.

Up to the next item on my list Wink

I tested one of the official YS MID files. Then, about halveway the player asked me to send the file to Worp3 for investigation. He wanted to check if the file was handled correctly. So I sent him the file, but started comparing the MIDIPLAY output to Winamp. The only difference was that MIDIPLAY played the file for 4:09 minutes and Winamp slightly won in 4:08 minutes.
I recorded both to wav and in Vegas I loaded one to a left panned channel and the other to the right. Besided having to slide the Winamp version to correct the speed a bit, the sound was identical.
MIDIPLAY just played a big MID file with ease. Great job Worp3.

Hi Worp3, your player works great but looks like it only uses the main mapper memory. Any chance in fixing this? Usually this is just a minor change in the code if you are using the DOS2 mapper calls.

On a plain Turbo-R ST it now only leaves about 80Kbytes left for the mid files, even with f.e. a MFR inserted. Luckily with the Nextor trick (holding '4' during boot) there is a workaround, but the real solution would of course be better Tongue

Nice to hear and you're correct it uses the default dos2 mapper.
It shouldn't be a problem to add more mappers if I had a bit of time for it. Unfortunately at the moment i'm having bit of a time issue to get really working on hobby projects.

Thanks for this test, nice to hear it all works like it should Smile
Sorry for not replying sooner, for some reason i'm just reading this now Sad
