Frequently Asked Questions
The sync is well-implemented, offering both hard and soft sync, but lacks the advanced routing options found on higher-end modules.
It's a licensed CEM3340 chip – a faithful recreation of the original, retaining its sonic characteristics.
It's versatile enough for a primary VCO, but its limited modulation capabilities might necessitate additional modules for complex sound design.
