jaslan, thank you for your response.
I am referring to the Windows software called dspMixFX. I understand, that this software allows to enable and configure DSP effects in the UR unit for real time use. It makes sense, that I should be able to move my UR unit between multiple computers and control real time DSP effects from any computer while playing live music. But that means I need to have that Widows software dspMixFX installed on every computer I connect my UR unit to, otherwise I lose the ability to control these live effects (e.g. adjust compression or EQ during live performance).
But I read somewhere, that this dspMixFX Windows software has to be activated (I assumed with the local software eLicenser, not USB one).
I see in your signature, that you are using UR44, which also has hardware DSP effects . Are you using dspMixFX Windows software to control these effects? Did this software require activation, when you first installed it on Windows?
