Would it be possible to have a mode with two SIDs where the first SID plays music and the second SID sound effects? Or does that create problems with lack of CPU time or would you run out of memory?

Well, I guess a lot more people than you may think have have a dual SID setup nowadays. I can think of:
- People who did plunder a SID from another C64 to install a second SID in their C64.
- 1541 Ultimate II(+) owners have three SIDs in their C64. The original SID, and two addional SIDs provided by the 1541U2.
Ultimate64 owners have three eight SIDs in their C64 as well. Ultimate64 owners have up to eight SIDs in their C64.- Mega65 owners have two SIDs in their machine.
- Turbo Chameleon owners have dual SID.
- Quite a few people bought an ARMSID. And if it was an ARM2SID, they have two SIDs in their C64.
- Owners of the FPGASID have two SIDs.
Some of these pieces of hardware sold quite well, for example the 1541U2 sold thousands and thousands. There I expect that a significant part of the user base nowadays has a dual SID solution.
Personally I both own a 1541U2 and an ARM2SID, that I have installed in my Commodore 128. I have quite a few C64s, that all have a single SID, so I may not always use a setup that is dual SID capable. However, for a game that does support dual SID, I will certainly grab my C128.
