After supporting the free Novation Circuit Editor for a number of years we have withdrawn it from our store following Novations launch of their own Components standalone editor.
You can find the Components editor here – https://novationmusic.com/components
All of our packs for the Novation Circuit can be installed using components. – https://isotonikstudios.com/product-category/novation-circuit/circuit-patch-store/
We do still support the Pro version of the editor available here – https://isotonikstudios.com/product/circuit-editor-pro/
For support as an existing customer please use the Support Request section within your account page, this will enable us to validate your purchase automatically and assign the request to the relevant developer to respond when they're available.
