here´s some stuff I´m still missing:
An envelope effect (in Ft2 it was Lxx) to set the start tick in the patterneditor for Volumeenvelopes and so on. Maybe could be useful also for automation envs.
Still having a libary off veeerrryyy old sample stuff which I´m to lazy to convert
Maybe you could implement *.smp *.voc and of course *.iff support ???
