Therevox Ondes VCO + Hakken Continuumini

video upload by John Schussler

"My uCVC module has arrived from Evaton Tech. It's a CV converter that takes the USB output of the Hakken Audio Continuumini (little sibling to the Hakken Continuum keyboard) and breaks it into usable CV outputs.

I got it specifically to use with the Ondes VCO, because the original Ondes Martenot after which the Ondes VCO is modelled used a...well what to me appears to be a ring on a string. So a continuous pitch movement rather than quantized by keys. I already had the Continuumini, so figured it should be a perfect match.

This is me running through the various voices on the Ondes VCO and different pitch ranges on the Continuumini to see what we get.

For a sequencer-based demo, see my earlier video on the Ondes VCO:"

"This is a first look at the Ondes VCO. It just arrived, and I'm so pleasantly surprised by the sound that I figured I'd put a quick video up so others can hear it as well.

It's not a 'standard' VCO. Based on the Ondes Martenot, each of its voices are, on the one hand, traditional (sine, square, triangle), and on the other specifically treated to give a sound that's unique. And because it allows for onboard mixing of waves, all sorts of variety is possible.

I'll dig in deeper later, but for now, have a listen to some of the very particular voices that come out of this module.
