Please do not think of Reaper as merely a sequencer. It is a fully-fledged DAW. It is a lean and mean program not bloated by a whole of instruments and effects that you might not want anyway. It is just about the most stable and solid program I have ever used. You can operate the 64-bit edition of Reaper and it will load 32-bit VST instruments and effects with its own built in bridging. I have never had any problems. I think it is an outstanding program.
