since as of now there isn’t a 64bit Renoise version, you won’t benefit at all of using Win7 64bit. Once a 64bit version will be available, you will be able to use more than the current maximum amount of RAM (2GB) in the same song.
using 32bit Renoise (the only available one at the moment) you will be able to use it exactly as you do on a 32bit OS: you will be able to run 32bit plugins, and won’t be able to run 64bit plugins. when using the forecoming Renoise 64bit, you will be able to load 64bit plugins and, by using some software such as jBridge, 32bit plugins
[s]not really/s. regarding Renoise strictly, be sure to have the latest version (2.5.1), since it features a fix which has been made to avoid that a recent Win7 upgrade frm windowsupdate.com causes Renoise installation to fail
Been using it for a while now (and the /3gb switch in the past) - not noticed any issues whatsoever although I’ll admit to not using renoise as much lately. Drivers for older hardware can be a pain in the arse, but other than that all is good. Also very pleased to hear a 64-bit Renoise is on the way
