FL Studio works under 64 Bit Windows and can already host 64 Bit plugins. In
addition by using 'Keep on disk' with Audio Clips/Sampler Channels AND OR
32 Bit plugins
you can have access to unlimited memory/sample size and fill your RAM to
overflowing, no matter how much you have, using in FL Studio 10 or higher.
It also means 32 Bit plugins will
require bridging, this is the same for all 64 Bit software, just as 64 Bit
plugins require bridging now under the 32 Bit software.
