General Chatter / Re: OPL limitations under MPTM?
« Last post by Saga Musix on November 16, 2018, 22:23:08 »
I cannot give you a detailed analysis right now, but from a quick look what I said in my previous post still holds: With all those NNAs, you will exceed the 18 channel limit of the OPL3 chip. You have 16 pattern channels playing OPL voices, and in particular the last 6 of them are written in a way that two notes are intended to be played at the same time - resulting in at least 22 voices, so at least 4 more than the OPL3 chip can handle.

In general, any limitations appliying to a real OPL3 chip also apply to OpenMPT.

I've managed to reach more consistent sound into the edit, listen to attached file.

Ok, then I´ve kind of put the idea out there, for those interested in the original scene vibe, which now is 32K size limit.

Peace!

There are two things happening here:

The hardcoded OPL amplification changed from 8192 to 6169 to make one FM operator as loud as one sample voice. This is mostly relevant for MPTM - this is not the difference in volume to make up for S3M levels, it is just to make the whole thing more logical to the user!
So to "undo" this change in S3M and have levels as loud as before (assuming VSTi slider set to 48), we multiply the sample volume by 6169 and divide by 8192, which gives a sample volume of 36.

However, this would assume that the user-definable OPL volume amplification didn't change. But it changed from 48 to 36, so we need to decrease the sample volume even more, we need to multiply by 36 and divide by 48.

Both of these combined are roughly equivalent to multiplying by 36 and then dividing by 64.

For S3M files, you will notice that the "VSTi" (i.e. OPL) volume is now at 36 rather than 48. If you could save the value of the VSTi slider in S3M files, the old settings would now be a 64. But since it will always revert back to 36, you need to change the sample pre-amp instead: Multiply the sample volume by 36 and then divide by 64. So if your sample pre-amp was previously set set to 48, it would now be set to 27.

For MPTM files, you can either do the same as for S3M files, or do it the other way around: Multiply the VSTi volume by 64 and then divide by 36.

Did you mean divide/multiply by 48? I looked at the code and the change was 6169 instead of 8192, which was 0.753x change and 36/64 is 0.563 :P

Anyways, I'll reupload my old entry with fixed volumes and I might also submit a second entry if I can finish it in time...

To me, trackers really only is about keeping the scene vibe alive, which was the reason for tracker music to begin with. Which I feel is best preserved in such a format.

Peace.

You can probably save some KB here and there by converting all samples to 8-bit. after all, 16-bit samples are not even supported by ScreamTracker 3 itself even if they are part of the format specification. So if you are going for S3M format, I would suggest to keep the ST3 limitations in mind - otherwise, you could just as well use MPTM and make use of its sample compression.
