Today I whipped out a progression with ChordPulse, picked a style and saved as MIDI. Dragged the file into Sonar with an instance of TTS-1. It was super quick and easy to have it playing in Sonar, ready for additions, tweaks and replacements. Very kool piece of kit.
I will likely go ahead and upgrade my ancient BIAB version with the current MegaPak just because I can for what appears to be a really good deal. We'll see what Black Friday brings.
In the mean time, ChordPulse is perfectly capable of providing a conduit between my head and Sonar.
