Annoying mixer bug

I am working on creating improvised live sets that need to be a smooth as possible when transitioning between elements. Therefore, I usually would want to introduce a new instrument by slowly fading it in after writing the part for it.

Say you select a blank track and pick a preset. You then move the mixer fader to 0 so you can sequence the part without making a sound, so that when it’s done, you slowly fade it in.

The problem is that after you turn the mixer down, when you press a key there is a short pop, or click. After that, it is silent as it should be. This is very annoying as it ruins the flow.

This happens on every type of instrument.
