2 questions, multiple instances, possible issues with grounding?

[Mantras]

Is it possible to run 2 or 3 instances of the Usamo VST plugin at the same time, sequencing on different channels?

I don't have grounded outlets in my home, will using the Usamo cause grounding loops between the soundcard - mixer - synth? Resulting in 50-60hz hum.

Use one plugin per physical USAMO. You can send all 16 MIDI channels into the one plugin.

MIDI does not cause ground loops if properly wired.
