I am having a few issues with X2 automation lanes and am wondering if anyone else has these too? Try testing with Rapture, though they happen with every VST I've tried.
1) When inserting a track template that contains a soft synth and a midi track routed to the soft synth, automation write events do not appear anywhere in the track UI but they do playback. When I view the automation lanes on the soft synth's audio track and attempt to manually add the automation curve with the small + button, the soft synth does not appear in the drop down as one of the sources for automation.
2) The same issue as #1 occurs when I add an instrument plugin from the Browser and have unchecked the "Ask this Every Time" option on the Insert Soft Synth Options dialog.
I have both of the above issues with Simple Instrument Tracks and the older style MIDI Source, Synth Track Folder, and First Synth Audio Output configurations for soft synths. I am able to work around these issues by making sure the "Ask this Every Time" option on the Insert Soft Synth Options dialog is checked and not using Track Templates.
3) The starting position of knobs, faders, and buttons is not maintained properly. For example, if I start recording with the Now Time at 0 with a toggle button in the OFF position, switch it ON and OFF once while recording, when I play back from the start of the song the button starts in the ON position, even though it should be OFF. Faders and Knobs exhibit this as well.
4) Automation that is visually depicted in the UI as being recorded while recording disappears after recording stops, and does not play back. By visually depicted, I mean that I see a curve being written while I'm recording. I've only seen this happen a couple times.
