Ok, i checked this a little yesterday. Gonna dig deeper today.
First of all. 1 and 2 are working, i didn't checked LFO phases yet.
1. I messed with this feature for a while. It works indeed. Sounds cool. Tried some exotic and not so exotic scales with Octatrack's overmodulated arpeggiator. PFM2 can sound like gamelan orchestra from Saturn now
(especially with Note scaling it sounds super organic and natural) or everything can be slightly re-tuned, awesome. Gonna research further this feature and make some measurements in Mapping department, comparsions with other scala implementations etc.
2. This feature works too. I did not delved in details yet. Have to find sweet spots, gonna try this with basic operator setups and so on. But yes, you can get interesting results with this feature already.
Found a little problem, maybe it is my fault, will investigate today. It loads default patch now and doesn't save this setting after chaging it to Bank or Combo. After reboot it loads and shows 'Default' in settings again. Also could not get USB midi to work, maybe it is my fault too. Was pretty tired yesterday.
Gonna say PreenFM2 became even more awesome. Thank you Xavier!
