Hey Mario, that's a valid point.
I'm mostly coming at this from an ease/speed of workflow pov. I hate having to hunt for things and tweak when I'm trying to get my ideas down. TTS1 is great because it has a broad palette and i can find a sound with one or maybe two clicks - then be on my way. And it responds to panning. It just works.
I'm looking for that in another package, and it needs to be 64 bit to work with DP. That knocks out some soundfont contenders like Jeskola, which i believe is 32 bit only.
The M1, while not a gm module, does have a fairly broad palette of sounds and is pretty speedy to use. So while it would be different than using the patch browser within sonar, i find it intuitive and lightweight ootb.
All things being equal, the Roland Sound Canvas might be a better TTS-1 replacement. But until either cakewalk or Roland Fix whatever prevents proper selection of banks and programs, it's less desirable than it otherwise would be. Maybe they'll get around to an update soon.
Thanks
Mike
