I no particalr order.
1. A real copy function for samples and patterns alike
2. Resampling of a sequence (it could be that dsp power of the 404 is too low for this)
3. Panning on mono samples
4. 24 backups instead of 12
5. a proper pitchshift (12 semitones up and down)
6. being able to store bpm per pattern.
7. other time signatures than 4/4 while we're at it
