Ymt-payer for the ST

Hi all

now that it is Christmas and other have give things to the community, i thought that i all will add to that, so i been fighting to get this little program finish.
i have add mouse control to make it easier to control, but that was not so simple and meant that i had to redo big parts of the program.
so there can very well be some bugs in it, i have not tested it on real hardware, mine is stash away.

it should works under STeem.
know bug, if switching to Drive A/B and there is no disk in, the program will come with a standard dialogue box and hang.

THX to the people that help me tested earlier versions of the program

 

 

to see the program in action

a little info about the program.

YMT files are like the YM/AY files.
Music files where you sampled data from the sound chip register (YM2149/AY8910) in a certain interval, instead of having a dedicate player.
up to now (to my knowledge), there have only been YM/AY player that could play tune/score files, that was sampled at 50HZ, but the YMT player can play files up to 300hz (there are some 50hz+ tunes/scores include in the examples)

the advantaged of AY/YM/YMT format, is that to replay these tunes/scores cost very little CPU power, so if you need a lot power for a eg. a 3D demo,
when it could be a wise choice to use it, because it leaves most of the CPU power for 3D calculations and the graphic etc.

and the disadvantaged is that it use a lot of memory, and also that it is nearly impossible to make a routine that can capture and use the SID sound and Samples etc.
it is also why those files need to be hand made, that is the reason why YMT-Player only support pure YM2149 sound.

Merry Christmas all
and may 2015 be a good Atari year
Peter

Being new here, I've been going through some of the older posts.. and look what I find!!

Hey Peter :-) YMT Player is indeed an awesome creation. How's everything going and is there any news on other ST projects or updates to YMT ?

 

Cheers matey.

Hi Steve

thx again friend

 

YMT is on hold right now need to have something tested on real hardware first.

so right now i am working on my drawing program, one of my friends found an error in it, and i have decided to expand a feature so it can save the clip as sprites.

the altering of clip routine should have taken max a week to do, but it has taken a couple of months now.

i have also started on a interface for a new program, can't say more about it here, will tell you later

 

but all is moving so slow at the moment, i just can't seem to find the energy for it.

YMT is such an incredible piece of work - so I wish you much success with your Atari ventures my good man.

Any testing or messing about ; ) that needs doing then i'm always happy to help.

Sadly, no real hardware (thanks to the wife!!) but i've Hatari and also a Falcon/MiNT setup in Aranym.

 

I know what you mean about energy. lol it's called getting old

[fedepede04]

you are right, it is probably age, and also please remember, do not let a surgeon have to much fun inside of you, it is also a bad idea .

and i also know the wife thing every day my space is getting smaller and smaller .

 

another thing i can see it is the first version that is uploaded here, maybe i should try to get the latest upload later today.

new version 1.02 aka 1.01b

ups i forgot here is a video on how to convert ym files so you can use them in the player

Hey I think that's newer than mine? Sure mine is 1.0.1.... hmm i'll have to check!

Yep, YMT Player is so cool. I'll have to check to see if it works under MiNT (I know, I know ...)

So, the wife reduces your computer space too? Not just me then!! lol

yes it is newer, i have removed 2 very small bugs, but nothing that matters when using it on a emulator, the reason why i not have released it is, I have waited for it to be tested.
it is not only my computer spaces that have been reduced, i used to have my own office, where i had all my stuff, but then we got Maria, so new all my music-keyboards are under my bed, in the closets, but i think that it could be worse, i still have two desktop computer and my digital piano my xbox 360 and my sega mega drive, in the living room. but it is a continuous struggle to keep it

Trust me, that ain't gonna get any better. Sorry for the bad news
