Special Mention

Firstly, a big thank you to the patient customers who have purchased, fitted or fed back information on any kits or assemblies that have been supplied. The appreciation from the community makes it all worthwhile and keeps the Roland Super JX and other retro synthesizers alive and kicking.


Many people have directly contributed and supported these projects.



Frédéric Vecoven for handing over his display project that contained a huge toolchain and concept design. His achievements for the Super JX are particularly remarkable: The replacement Super JX OS for JX10, MKS70, PWM upgrade and of course the M1024C Memory Cartridge. His website covers many other fascinating electronic projects too. Vecoven Website
