Propellerhead headquarters unleashes another sneak peek at the Pulsar Rack Extension! In this example Pulsar is modulating a Thor pad sound "using the built-in envelope to trigger a rise and fall in speed." The details of Pulsar haven't been made public yet, but on the RE page Propellerhead describe Pulsar as:
"Pulsar LGM-1 is a dual channel modulation power house for the Reason rack. We call it a dual LFO but it’s also a powerful little synth in its own right. More info coming soon."
