Suggestion- if you're running a 32-bit version of a DAW only use the 32-bit plug-in... my issue was running ableton 8.2.2 and had the 64-bit version of the plug-in and my CPU would jump to 90% just by touching the RMX1000. Once I switched the plug-in back to the 32bit version it worked well. Also update all your drivers in Win7 cause there was one crucial update that made everything work released from Microsoft in November.
