As one of the 'official' beta testers for n-Track ver 6 I would like to add my amen to those who would rather see existing issues taken care of first and foremost before moving on to ReWire.

I can't mention here the many times new 'features' have been added and frankly created more bugs to chase, while the stability and engine and compatibility issues were ignored.

I would suggest scouring the forum(s) and taking care of existing issues first.
