Vortex Sound Research

I’m trying to find a site detailing all of Roland’s products over the years. I keep coming across products I’ve never heard of and would love to find a comprehensive list, ideally with details about each piece.

Vintage Synth Explorer has a lot of stuff, but I don’t think it’s a complete record. The Roland site has some history, but it’s more a cursory historic overview than a comprehensive guide.

I know there must be some rare and short lived products they made over years, but where can I find out about these?!?

If there’s a site that has comprehensive info about other manufacturers, that would just be heavenly.
