Osc 2 bugs and others

[Oberheim 8000]

I have problems:

1. if i select osc 2 and change to wavetable, i get pitch integers instead voice (unison). If i load one saved preset, it change back for voices, but if i load my preset, it change back for pitch.
EDIT: i create new instance of SM and try new fresh wavetable. I get integer instead voice only in Layer 2 for both oscilators.

2. if i save my wavetable, and load it under osc 2 or 1 (it does not matter) the first and second wave change to different wave, other waves looks the same.

3. in Layer 2 under osc2 i load my supersaw preset. My supersaw preset was created by Additive synthesis, but after load it, i get it in Wavetable synthesis - i get 8 saws in each wave table. It is strange.

4. FM - if i set Mod3x4 it show me Mod2x4, and it is not correctly.
