here's another quirky thing I am noticing when you are playing organ with a slow leslie like Whiter Shade, etc, and hit the assignable button to turn leslie on fast it goes INSTANT ON fast and its very abrupt also....not a nice slow increase.....this also needs major attention....here are some examples.....honestly the Roland EA7 kills this sx900 in the organ leslie department..
