Author Topic: .49 Replay bug on certain modules (Read 5776 times)

Full Version:
OpenMPT v1.17.02.49

Has the bug occured in previous versions? If yes, please specify version(s): (This option is optional, and doesn't need research. But in case you know...)
Yes, all versions

Description of the bug:
Showcase: power of darkness
skip to the second pattern and have look at the piano part. the piano is retriggered EVERY line where a "01" is. This is not normal. When I copy the column into another module (Aim for IT playback disabled), this does not happen. no instruments are used in this module, so it is even stranger. It works correctly in IT and XMPlay.
The behaviour is caused by the "Aim for IT playback" option, but it's definitely DIFFERENT to the IT behaviour.

How often does it happen?:
In several modules by this author.

Confirmed - thanks for the report. Another source said that "If a sample number is given without a note, Impulse Tracker will play the old note with the new sample.", but if things go wrong compared to Impulse Tracker, apparently that statement forgets to mention that the new sample must not be the same as previous.

A correction to the occurance in other versions: "Aim for IT playback" was introduced only a few versions ago so this bug shouldn't occur in all previous versions.

Also, if this bug becomes too much of a problem, autodetecting the playmode can be disable by adding lines
[Misc]
AutodetectITplaystyle=0
to ini-file(if there already exists line "[Misc]", the lower line can simply be added below it).

I think that this "sample number retriggers sample" only counts if the sample already stopped. one has to test this.

Fixed in .50 test build.

EDIT:
It works okay for "power of darkness", but not for "Trance Nation".
testcase
skip to pattern 0 (position 4) and play channels 4 and 5 only. you will hear that the note is retriggered after the "^^" cut command on Line 18 through instrument 14, although it should not (behaviour differs from IT / XMPlay playback).

Thanks for the report. Seems to be somewhat different issue but the topic is wide enough to keep the thread open

Look, now it's still wrong on channel 6 and 7!

Also at position 4, the samples on channel 6 and 7 are repeating, although they should not.
Sorry if i'm bugging you, but this is kinda strange, isn't it?

If things are not fixed, it's of course worth bugging about. And anyway, I think this is that kind of bug that without relentless bug reports it might never get fixed

Whoooa, thank you

Finally, all modules sound right!
