I'm sure we covered that in another thread 
It's all about signal path: the knobs on the step sequencer are at a different (earlier) point in the signal path than the mixer channels, plus the mixer channels can handle multiple sounds from the step sequencer - and even multiple mixer channels can handle sound from the same step sequencer sound!
Sometimes there won't be a difference, other times there will. I'd really recommend learning more about how signals are routed through a system and how the order in which things occur can affect the sound.
Whether or not there is any difference depends on whether the effects in the path are linear or non-linear - and I mean 'effect' in the looser sense of 'anything that changes the sound' rather than just plugin effects, so that would also include gain stages, clipping, summing, noise on analogue signals, etc
Example:
In a digital system, gain is linear until the level reaches 0dBFS (it clips), at which point it becomes decidedly non-linear. As long as your signal doesn't clip at any point, if you just had a series of gain/attenuation stages in your signal path, it doesn't matter which order they're in - the output signal will be the same. The same goes for EQ.
But as soon as you add a compressor, which is non-linear, the order starts to matter. The linear stages before the compressor can still go in any order without changing the sound and the linear stages after the compressor can go in any order without changing the sound. But if a linear stage is moved from before the compressor to after it (or vice versa), there may be a difference in the sound.
The volume knobs on the step sequencer in Fruity are gain stages right at the start of the signal path. It then goes through a number of stages controlled by the Channel Settings box, before being routed to a mixer channel. It then still goes through all of the plugin effects before it reaches the mixer fader, which is another gain stage. If all of the stages in between are linear and the signal doesn't clip, there (theoretically) won't be any difference between making a change with the volume knobs on the step sequencer and making a change with the mixer fader. If any of the stages in between are non-linear, then there may be a difference.
