<i>btw this still leaves the other issue open. What is the best way to setup a pulsar synth in your project and how can I hear it in the cubase environment?</i>
I thought I explained this pretty well for you yesterday?

Looks like you're making progress!

I love watching people's faces light up when they finally grasp the power they just got their hands on, so...
First, make sure you're properly receiving midi inside the Pulsar environment: plug in the midi for the Pulsar synth, wire it's outputs to a mixer, wire the mixer's outputs to the Analog (or digital) outputs, and attach physical cables to your speakers (hopefully this isn't too vague and you get the idea).
You can be sure you're getting midi when the little orange "MIDI led" lights up on the virtual pulsar synths (most have these, if not, try the Midi Channel activity for free at
http://www.earlyfirst.com)
Once you have sound working, you can record this by bussing or auxing the audio to ASIO Destination channels and enabling those channels for recording in ASIO inside cubase.
But you can run as many synths & devices 'realtime' like this, tracking them exactly like you would on a hardware module, until you run from DSP: only then do you even need to bother recording (probably via ASIO) to Cubase...
