Minor fixes and improvements
The following has been changed - Note::set_param now sets orig-values and does an apply_pfactor() - Note::reattack now also reattacks the filter's envelope - oscval[i]=0 has been removed as it's unneccessary in Note::get_sample() - in Note::get_sample: fm- and out-sums are calculated in 2SCALE now and scaled down (via >>SCALE) afterwards (instead of while every single add-operation) - the filter-envelope is now inited with the shorter constructor - todo-list updated
