Having tried 64 bit for some weeks now - I’ve gone back to 32. Its much more stable. I think it’s down to plugin compatibility, as the more plugins I use the more it crashes.
A lot of the plugins I have a still 32 bit and the convertor thing in the 64 bit version seems to have some way to go yet
Have you tried converting your 32bit plugs with Jbridge? I just started using N5 64bit and Jbridge seems pretty good so far. At 14 euro it’s almost free as well.
