hmm - sorry - b is openMPT probably.. .) I have just heard b. Something is wrong - but I am not sure.. Ok - you got me! This play just fine..   The a.zip - this should be because of ogg compression or another settings of your card what confused me


SURELY B.ZIP

listen the song - it plays a note out of the rythm completely!

I havent heard b but a is openMPT but this part plays ok, but not everything plays not play like this part of this one song.. Try the others demosongs.. It is the shame - yes - this one plays relatively ok..

OK, I don´t need the tracker, I will better wait for 100% perfect player  
OK, if 99% and I will not find the difference on first try..   But it is not a case of OpenMPT yet.

Yes, there are many differences between OpenMPT and MilkyTracker, most of them are because of MilkyTracker not supporting certain features, though. Another example in necrophilia.ams are the channel volume commands on channel 10/11 - they are supposed to turn the guitar samples on and off, as it happens in OpenMPT, but in MilkyTracker they are just played without any interruptions.
I don't really feel like counting features, but without even having to look I can think of several features that the IT format has which are not present in AMS - e.g. fully configurable MIDI macros, resonant filters and stereo samples. Compared to other formats, it also lacks DSPs (e.g. MT2, DBM), synthesized samples (MED), and many other things. The truth is - there is no single format which covers all other formats as well.

To be honest, I cannot spot any remarkable differences between the AMS2WAV output and OpenMPT's output for this specific song. Again, if you can spot any obvious errors - point them out. "I just hear the difference" is not a valid argument and suggests that you just want to hear a difference even if there is none. That helps neither me, nor you, nor Dege if he wants to try better.

It´s nice that some tracker can open as many formats - but what is it for if it doesn´t play like it may play??
This I will never understand..
The Velvet studio opens XM, S3M - it don´t open IT because it don´t know stereo samples.. OK - the Velvet studio then should open IT also - but why if it don´t support stereo samples - so it will not interpret it corectly?? It is just an example.. Sorry - but AMS on OpenMPT don´t play as it plays on Velvet Studio - try it and you must hear it! Nevermid that is must convert something to anything - it is not an argument! I would like to hear the AMS with all its features! You may NOT to have left the interpretation on tracker itself - the music is written somehow and it may play correct in any event! If something is able to open some format it may be obvious that it will play exactly as it was meant.
If you don´t hear the difference - I will send you exported MP3  if you don´t want to install Velvet Studio..

Yes, I did try Milkytracker. necrophilia.ams sounds pretty much the same in OpenMPT and MilkyTracker. Needless to say there are differences between OpenMPT and MilkyTracker, such as MilkyTracker resetting the default panning on every note, which is not intended behaviour. That's a limition of MilkyTracker interpreting the file as an XM file (whereas OpenMPT interprets it as an IT file). If it sounds "totally out", maybe you are using a really old version of OpenMPT? I think I've completely rewritten the AMS loader in OpenMPT 1.20 or 1.21, so try the latest version (1.22) if you haven't done so before.

How about if you find some big mistakes that OpenMPT makes in the conversion you simply tell me the details about them and I'll fix it?
See what Dege said. OpenMPT converts every format into its editable formats, MilkyTracker does the same - with the difference that it has less internal formats (MOD, XM) to choose from.
That's correct. There aren't many (if any) files that would make constant use of the up to 7 effect columns, or fine vibrato envelopes, or whatever...

I don´t know what is it about.. I just hear the difference..  
Try to make it play like Velvet Studio which can read also other modules and play it correctly..
Do the OpenMPT like Velvet Studio for Windows and the Player - this is what I would like to..  

The Velvet Studio is probably the most advance I have ever seen, and the AMS format is the most advanced format as I see it - every other format includes what Velvet studio (AMS) already has also.
You can see it in the PDF included - it can also open other advanced formats like S3M, XM, MTM and other.. And it plays correctly all of them!

Having another look into the tracker readme, it's the feature of the editor not the format itself, if I got it right. It's good.

This I don´t exactly understand.. If the Studio can do it and saves it in AMS, the format must also include it - no?

Yes..
I don´t know how can I help you if you will try it.. I only know about that also exists the player of the Velvet Studio AMS files. It is a small DOS 32bit utility. It is a part of the package with it and its name is VPlay.exe.
It is for DOS but it is 32 bit extended DOS. I don´t know how to reverse engineer this even tried it using IDA. But it is somehow packed with D3X DOS Extender by Adam Seychell. I have tried to unpack it using stubx tool, which may have been used to it with no success The only think it gaves me is that the code is starting at 2308h. I don´t think there may be the chance to get source code. Who knows if the developer is reachable yet and still has it.


You can also try to analyze the AMS2WAV converter. It is not packed and should be more readable.. But I am not familiar with this

It seems and extended XM with its shadowed instruments, vibrato (pitch) envelopes, etc.
Altough it has some very unusual features (varying track number for patterns, max 7(! my god..) effects per note, etc.) that seem totally needless for tracking, it does not seem impossible to be supported.

The only worrisome thing is the echo effect. As far as I remember it was mentioned in the tracker user guide but not in the format descripton.

Hi Dege,
yes, it is totaly crazy format Do you think you can make the correct player even that craziness? (and no echo description?) Then there may be the only way to make it correct to play - to compare the outputs from the Velvet Studio by some method.. earmetricaly? 
Thanks.

And? This is just because OpenMPT must convert any file into one of its four editable formats

You talking about nonsense..
You obviously didn´t try Milky Tracker. It plays much better but not everything is good also! OpenMPT plays like it just play notes - it is totally out - and if it is because of that it must convert ?? - how you can convert something what OpenMPT don´t support??? 

And then - it is just a tracker - we are talking about to play the AMS format (of course the right way!) - not to convert to MID then play 

You say - don´t drive formula - take a bus - it is the same

if any player had major issues with this tune because of its samples, it wouldn't be able to play kind of chiptune correctly.

Not true, if you have a sample only few bytes long or a sample long about 20kB it is a big difference if you take out one byte - it must logicaly affect the sound pitch while for the 20kB sample you should not hear any pitch. Not many chiptunes has as much short samples like Charts Overdrive.
