If you are only selecting the instrumentation,,,don't use Cakewalk...Use the DisCover 5.
It is better and easier to use the DisCover5 than Cakewalk.
This is the beauty of Roland's design..
The only reason to use Cakewalk is if you are sequencing...even then, I use a Roland keyboard[G1000].
The DisCover5 is based on the same sound maos as the VA series[7 and 76]..4 maps..map1 is SC55, map2 is G800, map3 is G1000, map4 is VA 7...
