No, not with what you told us. In all humility and embarrassment, we have absolutely no way of estimating what you will try because we couldn’t estimate what we’d try. Honestly, every one of us did stupid things as we built our first presets and we’d run into CPU warnings. Again, and again, but maybe not again because that was “those people”.
Sh’yah, until you get the unit.
A basic rig will easily fit in a FM3, though, without having heard the difference between high res reverb and economy, I don’t know why you’d try to specify that. Economy is excellent for normal/live use IMO. But either way that should fit without a problem. But like kids in candy stores we run amuck, crash into something, and get told that won’t do, but the Fractal is benevolent and will let you try again.
On an FM9? You’ll have to try harder than that to break it. That’d fit easily into an FM3. I didn’t test it, but I’d expect that sort of preset would fit with a lot of room to spare. Mine are a lot more complex and they fit inside an FM3 without problems.
But, seriously, without hearing what sort of reverb Fractal includes, you shouldn’t try to say “high quality”. They take no prisoners, especially on the FM9. The “economy” reverb is great for live work. “Normal” is great for accompanied studio work, and above that you are into “I can’t tell the difference”.
