The scheduler has been rock solid for 2 years. The sequencer has a bug or two, but I think I managed to crash it only once this year in dozens of hours of using it and did not loose any work.
Nutcracker certainly upped it's anty this year and will be interesting next year with the version 4.0 twist to the grid, but when you get serous about your pixels and your sequencing, LSP is where you will end up.
Hopefully we will see the re-write in a few months, but I'm just continuing on with the sequencing as I was behind last year with wifey projects. Time to rotate over nearly all the songs this year to new ones. Maybe have a retro day once a week.
Join the facebook group, it's a WAY more active than the forum for LSP, occasionally even the developers chime in.
