- XM reader now supports up to 256 instruments, even though FT2 only
supports up to 128. ModPlug Tracker again.
2006-05-22 18:43 UTC - kode54
- S3M reader was using the incorrect index into component for sample packing
when reading sample data. Was using n, should have been m.
2006-05-22 17:26 UTC - kode54
- IT renderer may have a bug with its time_lost / loop handling. Switchover
from sustain loop would compound time_lost onto itself for every note-off.
I'm not sure if this crap is even doing the right thing, especially in the
case of a sample with a sustain loop, but no main loop. Working around for
now by zeroing time_lost after note-off. (hall8.it)
- S3M reader ignores effects outside of 1-25 range so nothing can hit
internal effects which are XM or PTM only. (N4.S3M)
- IT reader now supports ModPlug Tracker extensions for up to 4000 samples
and mapping them with instruments. (hallowe.it.it)
- XM reader now supports instrument vibrato 4, random. Yet another ModPlug
extension. (hcw-st.xm)
2006-05-21 02:11 UTC - kode54
- S3M reader correctly reads all 24 bits of the sample memory segment
offset, fixing at least one file with >1MB of sample data (d-t-x_x.s3m)
- XM reader stops reading instruments when it has at least one valid
instrument and encounters an error, fixing at least one file with
too high instrument count in the header (drx-chri.xm)
- IT reader ignores instrument header signatures, since there seem to
be files with bad signatures on unused/filler instruments (dsouls.it)
- MOD reader can now be restricted to handling 31 sample files with
legal/known signatures only, so frontend can fall back on restricted
MOD loading for files with incorrect extensions (dreamer_0g.s3m)
2006-05-20 xx:xx UTC - kode54
- Modified silence skipping to hack around some "S L O W" effects crap
and a misused break to row effect
