I’ve wanted a Mannequins Mangrove VCO for a long time. What an oscillator it is!
That sound is just the Mangrove with audio-rate modulation of ‘air’ and slow LFOs on ‘barrel’ and ‘formant’. Reverb from a Strymon Blue Sky. I’ve only been playing with it for 20 minutes and have found sweet spots everywhere. Beautiful. I think a long partnership lies ahead.
Here’s the wonderful pitch dividing behaviour of the Mangrove as the formant control is lowered.
