This is the cord for velocity sensitiivity, set by default to 24% in every voice. It seems to work pretty well for synths and bass and the like, but I'm finding it too subtle for drums. I end up using percentages more like 48% or 60% or something for my drums, or else I find note velocity values from ~20-127 are all pretty similar.
Has anyone else noticed this, or am I just not subtle enought to hear this correctly on drums?
