Vortex Sound Research

I’ve been using a 1/8” male trs to dual 1/8 female ts (headphone splitter) in the mod matrix of my microbrute mainly in the lfo input to split the signal to other parts of the matrix to extend the possibilities of modulation of the brute since I basically got it till few months back when I finally bought a few different splitters for modular synths and euro racks and such... my question is have I been damaging the synth running a 1/8th trs into a mono source for so long?.... any feedback would be appreciated- cheers
