Weren’t there always two groups? A big one which I would call the Minimoog fan group and another one, probably much smaller, who preferred the ARP Odyssey? Ah… you are right, there is probably also at least a third. The one which favors both synthesizers. ;) Either way, both monophonic synthesizers have been used on hundreds of great recordings in the last decades. And beside the original vintage instruments we have seen several attempts to rebuild them.
