The whole point why I recommended the Maestro is because you don't need a daughterboard. The Roland ROM, which is used by the card's Dream synth chip (and which hangs on the MPU401 port) is *on* the card itself. In installers of games, in their sound setup screen, you just select the "Roland Sound Canvas" option (or equivalent), and you're good to go.
Also, the Maestro was not sold with a daughterboard. It has a connector where you can install one, but you won't need to.
And as already mentioned, since it gives you AdLib/OPL, SBPro and Windows Sound System (WSS) compatibility, the only thing that's missing is a CM-64 (which is an MT-32 with extra sounds for games that support them).
Maestro+CM-64 is really a kick-ass combination for retro PC games. The only thing closer to the sound of an actual SC-55 is... an SC-55. There is a small difference in reverb between the Maestro's synth and Roland's, but that's extreme nitpicking. For all intents and purposes, they sound the same.
