If you're going to do this a lot, you might want to name the Bus 'ES 1' so you can always see that the signal is sent to the ES 1. The first step is to send the output of Sculpture to a Bus. I will use Sculpture to trigger the ES 1. In this example, I have created two Audio Instrument track in my Arrange window, and inserted ES 1 on the first, and Sculpture on the second. You can achieve interesting hybrid sounds and complex textures by using the output of a virtual instrument as the input of another virtual instrument.
