I was doing a session last night, and whenever I tried to expand the sample editor to view a newly recorded track, the waveform would disappear. The overview was fine but the body become a flat line. This has not occured in other sessions using Logic Pro 8. The other problem I'm having is with the piano roll (I still prefer matrix editor). When I zoom into an area using control-option-click - let's say around C6 at bar 32 - the editor zooms around bar 32 OK, but it centers around C3 instead of C6. Very frustrating! Has anyone experienced either of these issues? Thanks, Matt 15-in Mac Book Pro - OS X 10.4.10 - 2GB RAM - 828mkII
