That’s what the Space does when you change presets via MIDI PCs.
So you have to change your playing a little bit, like changing presets only when nothing is going on.
Or you can activate the preset with mix knob at 0, and then with a CC send the desired mix value. That’s what I do.
Also, make sure you save the preset with the mix value at 0.
If you are not using MIDI, then your unit must be defective I think because I’ve never heard of a similar problem.
