Frequently Asked Questions

It allows for negative frequencies, creating phasing and beating effects when used with other oscillators and modulation sources.
It’s genuinely useful for creating more subtle, nuanced control over the oscillators, though it requires a bit more understanding of CV relationships.
It’s a more 'classic' sounding VCO – less aggressive than some modern options, but with a clear and stable tone perfect for foundational sounds.
