In general VST 2.4 is platform independent. There are only three platform dependent opcodes :
effEditOpen
audioMasterGetDirectory
audioMasterOpenFileSelectorHere are the required API changes for 64 bit Mac OS X:
effEditOpen:
the [ptr] argument is a WindowRef on 32 bit Mac.
On 64 bit this is a NSView pointer. The plug-in needs to add its own NSView as subview of it.audioMasterGetDirectory:
the [return value] is a FSSpec on 32 bit Mac.
On 64 bit this is a char pointer pointing to an UTF-8 encoded string.audioMasterOpenFileSelector:
the VstFileSelect struct uses FSSpec's on 32 bit Mac.
On 64 bit Mac these are char pointers pointing to UTF-8 encoded strings.
