IToday I just realized some features from Studio One 4.6 (pro) seemed to be missing in version 5 (Pro).
1 The handles for adjusting automation curves are missing.
2 Softtube's Tape plug-in no longer appears as a Mix FX option,
3 Rewire library is 'out of date" and will not load.
4 In some of the Presonus such as Fat Channel, you have to double click knobs to get them to respond to mouse movement.
5 There are audio pops and clicks when turning on and off plug-ins, and all Presonus plug-ins now produce a 'Zipper' noise when changing values.
6 There seems to be no way to disable the Mix FX plug-ins in the effects browser manager section,
