hi, I've uploaded 3 patches to https://sourceforge.net/tracker/?group_id=69130&atid=523505 1) "Bugfix: Keep phi < wave_period": results in less crackles here. 2) "New SynthData::exp_table_ln2()": slightly (~6%) smaller cpu hunger. 3) "s/log(2.0)/M_LN2/": superseeded by 2). Comments welcome, Karsten
