As you probably read on the other thread, we have hardware limitations that make it impossible for us to increase the overall volume without introducing more compression.
It has been discussed that maybe we will provide some setting knob to balance between loud/compressed and quiet/clean sound. But we can't have higher output level with exactly the same sound color.
On the other hand, I think that this is a common issue on multitimbral synthesizers: for example, the output level is also low on the Nord Lead 2X.
