Welcome to Project CS

Update for May 8 ,2025
We would like to thank everyone for their continued support and inquiry regarding Project CS. Project CS is still ongoing however with the passing of Karl Frick our remaining design revision work falls solely on Tim’s shoulders and in all honesty Tim’s a busy man!!   
Karl represented 50% of our design team on projectCS and worked side by side with Tim directly to make everything you’ve all seen and heard to date regarding the mCard project.  In addition to project CS; RetroLinear’s been restoring not one but two Yamaha GX-1 synthesizers one of which is the actual GX-1 Keith Emerson played in the Fanfare stadium scene. Restoring these GX-1’s has entailed much R&D work which directly correlates to completing the most accurate GX-1 and CS series solutions known to date.

We kindly ask everyone to hold tight, things are moving in the right direction!

Thank you,
