|
|
hi all,
i've been discussing some 3xx problems with Baktery, and we tested a
few MOD and XM files with the effect.
Seemed that some newer XM files (e.g. Elwood - Fall from Sky) did work
correct, but that older (Amiga) MODs have a problem with the 3xx effect
in Skale. Mostly that the change in pitch is not enough, to reach the target
note. (e.g. Emax - Defloration [classic cool track btw =)) ]
We did think about the Amiga Frequency Table, but it seems that the
problem was not really because of that. Or so it seems...
For further analysis of this problem with 3xx mod effects, we would like to
have some good example modules, that use a lot of this effect. old ones
that go wrong, and newer ones that are alright, o ralso wrong perhaps.
So, if you know a song, please let us know where to get it, and also where
in the song the effect is used, so we don't have to search for it.
For example:
Emax - Defloration
problem:
first: songlist 02 / pattern 0A (appears in other patterns as well)
thanks,
baktery & st3vie |

This bug (at least I think it's the same one) appears in other pitch-related effects as well, namely 1xx or 2xx.
Moreover, I do think it's about the Amiga Frequency Table... I did a bit of testing with the MOD 'Savannah' by Uncle Tom of Scoopex which was composed in an earlier Amiga tracker because it uses the 1xx/2xx effects for vibrato instead of 4xx. A lot of other older Amiga modules do this too. Anyway, obviously another logical use for this was the "emulation" of the 3xx effect, which is where you'll notice the bug in Skale.
In Savannah, the buggy part is on track 0, position 1, pattern 5, rows 6 and 30 (not hex). In case you're wondering, as far as I know they didn't change the behaviour of 1xx/2xx in Protracker, nor the freq table of course, because mod.savannah works great in Protracker 2.3d even though it was composed with an earlier tracker. And the MOD format of PT2 is the one that's sort of became the standard.
Here's some results of my testing:

http://reed.planet-d.net/stuff/skale/savannah-ft2-amigafreq.mp3
http://reed.planet-d.net/stuff/skale/savannah-ft2-linearfreq.mp3
The reason why I think the problem is related to the Amiga freq table is that when the module is played in FT2 using linear frequency table, it sounds pretty much the same as when played in Skale. When played in FT2 using the Amiga frequency table, it sounds pretty close to Protracker, which should be considered the "right" way.
Oh and the original module can be found here, for example:

just add the option for choosing 'linear frequency table' or 'amiga frequency table' like in good old FastTracker-times.
