It's been a while since I worked with the Virus, but I'd say yes, it's similar.  The Harmonizer sequencer outputs a "mod" signal, so you can hook it to anything that takes mod signals as input.  To control the sequencer, you'll have to attach something to its input to tell it which step to put out.  For example, if you want to sweep from the start to the end, attach an LFO with a ramp to the input.  If you want to sweep up and back, put a 50% duty cycle triangle on the input…
