X1/X4 can work in 4 Output Modes:
1. L&R only (all effects)
2. L&R (all effects) + OUT3(dry)
3. L&R (all but without reverb) + OUT3&4(dry)
4. separate 1 2 3 4 (dry)

This is according to official manual, and actually it's true, but modes 2. and 3. have software bug: you can get effects on L&R only if you "cheat" the software. See more in my topic "SW Bug in X4 OS 4.0a".
