Zeroscillator by Cynthia Industries

A non SynthTech module on the site?

I won't do this too often, but this module is special, it is a MOTM format VCO with FM capability, but not just any FM, it is FM that has a smooth crossover through zero, something that has not been acchieved with an analog module until this module came along.
It's pricy, $750,- plus shipping, but it's worth the money. Go to Cynthia for more info on this great module. Be sure to check out the samples on that page.
