Your Hammond organ is NuBi LE with Spinner LE Leslie simulator.
And to run that you're going to need a stand-alone VST host like Chainer.*
Then if you're using a soundcard that doesn't have ASIO drivers, you'll need ASIO4all.
If you want to add an electric piano to all that lovin', check out the 4Front Rhode.
Minihost although it will only run one VST instrument or effect at a time so you can't use the organ and the Leslie simulator together.
