The 32 bit and the 64 bit versions of n-Track Studio will be developed in parallel and the latest build of the program will be available in both formats. The 32 bit and the 64 bit versions are two separate setups that can be installed independently and won't interfere with each other.

A number of limitations currently exist:

• The 64 bit version only sees plug-ins compiled for x64 CPUs.
• VST plug-ins are not supported as the VST specification doesn't yet include support for x64 architecture.
• The surround panner and the n-Track Graphic EQ, Multiband Compressor and Tempo-Delay plug-ins are currently not included.
