I'm curious to why you say that. I would have said the odd one out of that bunch you mention was the SC. The MT32 and D10/110 were based on L/A synthesis architecture and shared the same voice construction based on partials. Many of the same patches in the MT32 were also found in the D10 as well. I remember editing patches on both of those tone generators and the available parameters were very much the same other than the D10 had performance patches as well as the multitimbral patches. I could be wrong but from memory the SC was much more of a sample playback module without the L/A synthesis architecture.
