I don't know if the featurelist is old(plus my german is a bit rusted), but a few essentials seems to be missing:
- loading OGG- and FLAC-format samples
- recording song/individual tracks as wav/mp3/ogg/iff
- basic effects.. filters(at least cutoff and resonance if nothing else), reverb, equalizer, compressors and delay...
- midi-support
ogg/flac format support is a bit downer, most of my samples are in either format.
