I'm not sure if this is a FL specific problem or something to do with RAM or buffers or whatever, but I figure I'll ask here.
I have this project that sits at around 60% CPU use while idling with all tracks and plugins on. Playing, it goes up to around 80-90%. Everything is all fine and well until I export to MP3 (or Wav). In the MP3, my drums from Battery 2 drop out randomly, as if I had inattentively wiped the erase button all across the piano roll prior to rendering. It seems to get worse as the song goes on, actually. No other track but the drums has this problem.
After I export, the same thing that happens in the render starts happening in the actual project, and doesn't stop until I reload the project. Strangely, if I save the Battery kit with a new file name it fixes itself. (Until I render again, and then the same thing happens.) I've messed around with buffer lengths and that doesn't help.
I've made a billion songs with all the same plugins and stuff in the past, so it's definitely not a problem with something new I'm using, or a different setting or whatever.
Specs: (In case someone needs 'em)
1.5 Pentium M
1GB RAM
AC97 Sound
FL Studio 5
Not using a MIDI controller
Also: When I import MIDI data from Guitar Pro 4 to FL Studio, the slides and bends for the guitars don't carry over either in MIDI Out or in a VSTi track. FL just plays the bent note's root or plays the two notes detached. Any way to solve this?
