I remember this problem happening years ago, but it was fixed by an updated version. Well, it's back.
Basically S1 skips random MIDI notes during playback. It's never the same note. I'll be watching the cursor scroll through and it'll just ignore a note, but if I stop it and play the section again, it'll play the previously missed note, but might skip one or two others somewhere else along the line. I haven't mixed anything down since this started happening, so I'm not sure if it will skip notes in the final recording, or if it's only during playback. But either way, it's quite a problem.
(I've experienced it so far with two different piano VSTs.)
Is anyone else noticing this since the latest update of S1 5 Professional? Thanks!
